FAQ Date: 24 May 1993 17:38:17 -0400 Organization: The University of North Carolina at Chapel Hill Lines: 1121 Distribution: world Message-ID: <1trf89INNr8d@carissimi.cs.unc.edu> NNTP-Posting-Host: carissimi.cs.unc.edu This is an attempt at providing a comp.sys.sun.hardware FAQ. I've compiled in many articles' worth of information which I've collected >from c.s.s.h over the years. It is by no means complete, (or guaranteed correct) however, and I'd welcome a bit of "filling in the gaps." Having said that, I also make no promises to update and regularly post this FAQ. I'll do what I have time for. I've stripped all the stuff from the included articles except for the pertinent information. No permissions were asked for. (If you post it to the net without a copyright, it's fair game!) Last update: 5/24/93 Where to find other information: -Check out the comp.sys.sun.admin FAQ Sections: 1. Pinouts 2.

Used the original Stanford-designed video board. Uses a parallel microswitch keyboard and parallel mouse 100 Used design similar to original SUN (Stanford University Network) CPU, version 1.5 CPU could take larger RAMS. Pre-dates Sun's 4.2 port (ran Unisoft V7) (68010 CPU instead of SUN's 68000) 10Mhz. 100u "Brain transplant" for 100 series. Replaces CPU and memory card with first-generation Sun2 CPU and memory boards so original customers could run SunOS V1. (Still has parallel kb/mouse intf so old kbds would work.) 170 Rack-mounted server. Slightly different chassis design than 2/170's Sun 2's 2/120 Multibus-based 68010 10Mhz. First machines that had desk-side chassis Serial Microswitch keyboard, Mouse Systems Optical mouse. 8Mb memory max. Cards are CPU, 1 or 4 meg memory board, ethernet board, SCSI board, 640 * 480 color board, monochrome video board, SMD controller, tape controller, 16 port serial mux (ALM-1) Two variants of video board, one generated TTL-level video, on ECL. Later video boards ("2prime") could generate either levels. Early 19" mono monitors (philips or moniterm) could be switched as well. 2/170 Rack-mounted Multibus chassis server 2/50 VME Sun2 style CPU 2 slot chassis. Optional SCSI board (model name is SCSI-2; 2'nd SCSI design.. first was for 2/1xx's) sat on mem expansion board in 2nd slot. CPU board had 1,2,or 4 megs mem, 10Mhz 68010 CPU, ethernet, two serial ports. Memory expansion boards are 1,2 or 4 megs as well. The (type-2) keyboard and mouse attached via an adapter that accepted 2 modular plugs and attached to the DB15 port. 2/160 First machine to use 12 slot desk-side VME chassis. Many have CPU upgrades to 3/160's. Had 4 fan cooling tray instead of 6 in later machines, thus cooling problems with lots of cards. Also only had 4 P2 memory connectors bussed instead of 6. SunOS 4.0.3 was the last release with Sun2 support 2/1xx's with a monochrome display can only have 7megs max, since the frame buffer appears in the 8th meg Sun 3's 3/160 First 68020 based Sun machine. Uses "Carrera" CPU, which is used in lots of other Sun3 variants. 4Mb on-board memory. Sun's mem expansion goes on 4 Meg memory expansion boards; third parties had up to 32 megs on one card. SCSI was optional. One variant of the memory card held the 6u VME SCSI board, other version sat in slot7 of the backplane and ran the SCSI out the back of the backplane to the internal disc/tape. CPU has 2 serial, ethernet, kbd ports. 3/75 2 slot desktop chassis, optional SCSI sits in 2nd slot on mem exp bd. 3/140 3 slot chassis 3/150 6 slot chassis 3/180 12 slot rack-mount chassis 3/110 similar to Carerra CPU, but has 8 bit color frame buffer on board and uses 1meg rams for 4meg on-cpu memory. 3 slot VME chassis. Code-named "Prism". 3/50 15.7MHz cpu, cycle-stealing monochome frame buffer. 4mb mem max (3rd party mem expansions boards were sold, though) No bus. On board SCSI. Code-named "Model 25". 3/60 20Mhz 020 cpu, VRAM monochome frame buffer. optional color frame buffer (could run mono and color from same board) on special P4 connector. No bus. On board SCSI. SIMM memory up to 24mb (100ns * 9 SIMMS). High (1600*1100) or low (1152*870) resolution mono selectable by jumper. "GX" frame buffer also was avail. Code-named "Ferrari". 3/60LE A limited version of the 3/60 with no on-board framebuffer. It also is limited to 12MB of RAM (4MB of 256KB SIMMs and 8MB of 1MB SIMMs). 3/260 3/280 25MHz 68020. 2 serial ports, enet, kb on CPU. High resolution mono only. No CPU board memory (space taken up with a cache). Memory boards in 8 meg increments. "Sun4" 32meg boards work (at least for the first 32 megs, never had more than one to try 64...) Memory boards from earlier machines cannot be used. First Sun with an off-chip cache; 64KB, write-back, direct-mapped, virtually-indexed and virtually-tagged, with 16-byte lines. For the above Sun 3's, the (type 3) keyboard plugged directly in to the DB15 connector. The (type 3) mouse plugged into a modular jack on the keyboard. 3/80 68030 CPU. Similar packaging to SparcStation 1. The 030 machines were actively marketed, since Sun had decided to drop the Sun3 line soon after the machines were announced. The 3/80 has a 68030 running at 20 Mhz and a 68882 at 20 or 40 Mhz, parallel printer port, SCSI port, 15 pin Ethernet, 3.5 inch 1.44 meg floppy drive, P4 video bus connector, room for 16 megs of SIMM ram. No onboard framebuffer. Code-named "Hydra". The 3/80 came with a type-4 keyboard & mouse, plugged together and into the machine with a small DIN plug. 3/470 3/480 Uses a 68030 and 68882 at 33Mhz, and has a P4 slot. These are fairly rare. Code-named "Pegasus". SunOS 4.1.1 was the last release with Sun3 Support Sun 4's 4/260 4/280 First SPARC CPU board; can replace the CPU in 3/260's or 3/280's. Similar cache to 3/2xx. Code-named "Sunrise". 4/110 First desk-top SPARC. CPU doesn't support VME bus master cards, so DMA disc and tape boards won't work with it. Really intended as single- board machine. Has on board SCSI, 2 serial ports, enet, kbd. "P4" frame buffer could be monochrome or color. Used "static column RAM" rather than a conventional cache. Code-named "Cobra". 4/330 4/370 4/390 Faster, has on-board SCSI, more serial ports, and accepts SIMMS. Similar cache to 4/2xx, only write-through. Code-named "Stingray". 4/4xx Write-back rather than write-through cache, 64 MMU contexts, 3-level rather than 2-level Sun-style MMU, 33 MHz CPU chips. Code-name "Sunray" (which was also the code name for the 7C601 CPU). Sparcstations: SS1 (4/60): code-name "Campus" or "Campus-1". SS1+ (4/65): code-name "Campus B". SLC (4/20): code-name "Off-Campus". IPC (4/40): code-name "Phoenix". SS2 (4/75): code-name "Calvin". ELC (4/25): code-name "Node Warrior", as I remember. IPX (4/50): code-name "Hobbes". The SparcStation 1, 1+, and 2 all have similar "small pizza-box" packaging. (The SS2 case is slightly larger and has more ventilation, i.e. fans). All have 3 S-Bus slots. The IPC and IPX have the "lunch box" packaging. Both have 2 S-Bus slots. The IPC has a built-in mono framebuffer. The IPX has a GX-accelerated color framebuffer. The SLC and ELC have the "it's all in the monitor" packaging. Both have 0 S-Bus slots. Both are also very quiet - no fans! The monitor is 17" monochrome. The SS1, 1+, 2, SLC(?), & IPC all use X9 30-pin SIMMs [speed?]. The ELC and IPX use X33 SIMMs. Other Sparcs: Sun-4E: SPARCengine 1E, basically an SS1 (or maybe SS1+, I'm not sure what the clock rate is) with a VME interface and 8K rather than 4K pages; sold as a VME board. Code name "Polaris". Sun-4m: SPARCsystem 6xxMP: first Mbus-based machine, 40 MHz Cypress/ROSS Mbus modules later upgraded to 40 MHz TI SuperSPARC modules. Sbus and VMEbus; code-name "Galaxy". SPARCstation 10 (which is a Sun-4m): Mbus-based, TI SuperSPARC modules, no VMEbus; code-name "Campus-2". SPARCclassic, SPARCstation LX: Sun-4m, but no Mbus.

If you have v3.2 or later of the boot proms you can install 40MB. Install 4M x 80ns SIMMS in the low order memory slots (1+5, 3+7) and 1M x 80ns SIMMS in the remaining slots, for a total of 8 ea. 4 MB and 8 ea. 1 MB SIMMS = 40 MB. If you have earlier versions of the proms you are stuck at 16 MB unless you can get a Sun F/E to upgrade them. ---------------------------------------------------------------------- Keyboard info: What do the DIP switches underneath the Type 4 and 5 keyboards do? There are several different layouts for the Type 4 and Type 5 keyboards, for different countries, as well as for the Magical Land of UNIX :-) (the Type 5 has, in addition to the various national layouts, a "UNIX layout" which puts Control and Esc, at least, where God intended them to be :-) :-) :-)). So that the OS/window system can correctly set up its tables for mapping raw keystation codes to key "identifiers", the keyboard can be sent a command asking what layout it has; it will send back a reply indicating the "layout code" for its layout. The KIOCLAYOUT "ioctl" (see KB(4M) in the SunOS 4.1[.x] documentation or "kb(7)" in the SunOS 5.x documentation) can be used by a program to cause the command to be sent to the keyboard and its result obtained. The keyboard layout is specified by 6 of the 8 DIP switches, on a Type 4, as I remember (I think it's also 6 of 8 on the Type 5). The DIP switch on the other end of the switch pack, on a Type 4, can be set to cause the microprocessor in the keyboard to report that it is a Type 3 keyboard, for the benefit of old PROMs or old OSes that don't know about Type 4 keyboards; that switch may do that on a Type 5 as well. Type 5's report that they're Type 4's; they're just set to have different layout codes. To see what the layout code is for a given layout, check out the files in "/usr/share/lib/keytables"; a file with the name "layout_XX" is for a keyboard with a layout code of hex XX. On a Type 4, as I remember from the keyboard spec, the one remaining switch does nothing; dunno what it does on a Type 5. On the Type 4, as I remember, if you have the bottom row of the keyboard toward you and the keys pointing down, the leftmost switch is the "Type 3 vs. Type 4" switch, and the 6 on the right are the layout switches; dunno which switches are which on the Type 5. (NOTE: the UNIX-layout keyboard doesn't have its own layout code; instead, I suspect the switch-to-keystation translation map in its microprocessor is different from that for other Type 5's, so that it looks to the software like, I think, a US-layout keyboard.) ---------------------------------------------------------------------- [please add more (relevant, frequently-asked) questions.] From mueller@cs.unc.edu Wed Sep 8 14:43:38 1993 Path: vulcan.iss.bnr.com!msc.edu!umn.edu!news-feed-2.peachnet.edu!concert!borg.cs.unc.edu!not-for-mail From: mueller@cs.unc.edu (Carl Mueller) Newsgroups: comp.sys.sun.hardware Subject: comp.sys.sun.hardware unoffical FAQ Date: 7 Sep 1993 23:26:23 -0400 Organization: The University of North Carolina at Chapel Hill Lines: 1279 Distribution: world Message-ID: <26jjcvINNokb@hatteras.cs.unc.edu> NNTP-Posting-Host: hatteras.cs.unc.edu This is an attempt at providing a comp.sys.sun.hardware FAQ.

Used the original Stanford-designed video board. Uses a parallel microswitch keyboard and parallel mouse 100 Used design similar to original SUN (Stanford University Network) CPU, version 1.5 CPU could take larger RAMS. Pre-dates Sun's 4.2 port (ran Unisoft V7) (68010 CPU instead of SUN's 68000) 10Mhz. 100u "Brain transplant" for 100 series. Replaces CPU and memory card with first-generation Sun2 CPU and memory boards so original customers could run SunOS V1. (Still has parallel kb/mouse intf so old kbds would work.) 170 Rack-mounted server. Slightly different chassis design than 2/170's Sun 2's 2/120 Multibus-based 68010 10Mhz. First machines that had desk-side chassis Serial Microswitch keyboard, Mouse Systems Optical mouse. 8Mb memory max. Cards are CPU, 1 or 4 meg memory board, ethernet board, SCSI board, 640 * 480 color board, monochrome video board, SMD controller, tape controller, 16 port serial mux (ALM-1) Two variants of video board, one generated TTL-level video, on ECL. Later video boards ("2prime") could generate either levels. Early 19" mono monitors (philips or moniterm) could be switched as well. 2/170 Rack-mounted Multibus chassis server 2/50 VME Sun2 style CPU 2 slot chassis. Optional SCSI board (model name is SCSI-2; 2'nd SCSI design.. first was for 2/1xx's) sat on mem expansion board in 2nd slot. CPU board had 1,2,or 4 megs mem, 10Mhz 68010 CPU, ethernet, two serial ports. Memory expansion boards are 1,2 or 4 megs as well. The (type-2) keyboard and mouse attached via an adapter that accepted 2 modular plugs and attached to the DB15 port. 2/160 First machine to use 12 slot desk-side VME chassis. Many have CPU upgrades to 3/160's. Had 4 fan cooling tray instead of 6 in later machines, thus cooling problems with lots of cards. Also only had 4 P2 memory connectors bussed instead of 6. SunOS 4.0.3 was the last release with Sun2 support 2/1xx's with a monochrome display can only have 7megs max, since the frame buffer appears in the 8th meg Sun 3's 3/160 First 68020 based Sun machine. Uses "Carrera" CPU, which is used in lots of other Sun3 variants. 4Mb on-board memory. Sun's mem expansion goes on 4 Meg memory expansion boards; third parties had up to 32 megs on one card. SCSI was optional. One variant of the memory card held the 6u VME SCSI board, other version sat in slot7 of the backplane and ran the SCSI out the back of the backplane to the internal disc/tape. CPU has 2 serial, ethernet, kbd ports. 3/75 2 slot desktop chassis, optional SCSI sits in 2nd slot on mem exp bd. 3/140 3 slot chassis 3/150 6 slot chassis 3/180 12 slot rack-mount chassis 3/110 similar to Carerra CPU, but has 8 bit color frame buffer on board and uses 1meg rams for 4meg on-cpu memory. 3 slot VME chassis. Code-named "Prism". 3/50 15.7MHz cpu, cycle-stealing monochome frame buffer. 4mb mem max (3rd party mem expansions boards were sold, though) No bus. On board SCSI. Code-named "Model 25". 3/60 20Mhz 020 cpu, VRAM monochome frame buffer. optional color frame buffer (could run mono and color from same board) on special P4 connector. No bus. On board SCSI. SIMM memory up to 24mb (100ns * 9 SIMMS). High (1600*1100) or low (1152*870) resolution mono selectable by jumper. "GX" frame buffer also was avail. Code-named "Ferrari". 3/60LE A limited version of the 3/60 with no on-board framebuffer. It also is limited to 12MB of RAM (4MB of 256KB SIMMs and 8MB of 1MB SIMMs). 3/260 3/280 25MHz 68020. 2 serial ports, enet, kb on CPU. High resolution mono only. No CPU board memory (space taken up with a cache). Memory boards in 8 meg increments. "Sun4" 32meg boards work (at least for the first 32 megs, never had more than one to try 64...) Memory boards from earlier machines cannot be used. First Sun with an off-chip cache; 64KB, write-back, direct-mapped, virtually-indexed and virtually-tagged, with 16-byte lines. For the above Sun 3's, the (type 3) keyboard plugged directly in to the DB15 connector. The (type 3) mouse plugged into a modular jack on the keyboard. 3/80 68030 CPU. Similar packaging to SparcStation 1. The 030 machines were not actively marketed, since Sun had decided to drop the Sun3 line soon after the machines were announced. The 3/80 has a 68030 running at 20 Mhz and a 68882 at 20 or 40 Mhz, parallel printer port, SCSI port, 15 pin Ethernet, 3.5 inch 1.44 meg floppy drive, P4 video bus connector, room for 16 megs of SIMM ram. No onboard framebuffer. Code-named "Hydra". The 3/80 came with a type-4 keyboard & mouse, plugged together and into the machine with a small DIN plug. 3/470 3/480 Uses a 68030 and 68882 at 33Mhz, and has a P4 slot. These are fairly rare. Code-named "Pegasus". SunOS 4.1.1U1 was the last release with Sun3 Support Sun 4's 4/260 4/280 First SPARC CPU board; can replace the CPU in 3/260's or 3/280's. Similar cache to 3/2xx. Code-named "Sunrise". 4/110 First desk-top SPARC. CPU doesn't support VME bus master cards, so DMA disc and tape boards won't work with it. Really intended as single- board machine. Has on board SCSI, 2 serial ports, enet, kbd. "P4" frame buffer could be monochrome or color. Used "static column RAM" rather than a conventional cache. Code-named "Cobra". 4/330 4/370 4/390 Faster, has on-board SCSI, more serial ports, and accepts SIMMS. Similar cache to 4/2xx, only write-through. Code-named "Stingray". 4/4xx Write-back rather than write-through cache, 64 MMU contexts, 3-level rather than 2-level Sun-style MMU, 33 MHz CPU chips. Code-name "Sunray" (which was also the code name for the 7C601 CPU). Sparcstations: SS1 (4/60): code-name "Campus" or "Campus-1". SS1+ (4/65): code-name "Campus B". SLC (4/20): code-name "Off-Campus". IPC (4/40): code-name "Phoenix". SS2 (4/75): code-name "Calvin". ELC (4/25): code-name "Node Warrior", as I remember. IPX (4/50): code-name "Hobbes". The SparcStation 1, 1+, and 2 all have similar "small pizza-box" packaging. (The SS2 case is slightly larger and has more ventilation, i.e. fans). All have 3 S-Bus slots. Their clock speeds are 20, 25, and 40 Mhz, respectively. The IPC and IPX have the "lunch box" packaging. Both have 2 S-Bus slots. The IPC has a built-in mono framebuffer. The IPX has a GX-accelerated color framebuffer. The IPC is 25 Mhz, the IPX is 40. The SLC and ELC have the "it's all in the monitor" packaging. Both have 0 S-Bus slots. Both are also very quiet - no fans! The monitor is 17" monochrome. The SLC is 20 Mhz, the ELC 33. The SS1, 1+, 2 & IPC all use X9 30-pin SIMMs [speed?]. The SLC, ELC and IPX use X33 SIMMs. Other Sparcs: Sun-4E: SPARCengine 1E, basically an SS1 (or maybe SS1+, I'm not sure what the clock rate is) with a VME interface and 8K rather than 4K pages; sold as a VME board. Has 1 SBus slot. Code name "Polaris". Sun-4m: SPARCsystem 6xxMP: first Mbus-based machine, 40 MHz Cypress/ROSS Mbus modules later upgraded to 40 MHz TI SuperSPARC modules. Sbus and VMEbus; code-name "Galaxy". SPARCstation 10 (which is a Sun-4m): Mbus-based, TI SuperSPARC modules, no VMEbus; code-name "Campus-2". SPARCclassic, SPARCstation LX: Sun-4m, but no Mbus. TI microSPARC chip, Sbus; code-name "Sunergy". Sun-4d: SPARCcenter 2000: XDbus rather than Mbus, multiple SBuses, no VMEbus, TI SuperSPARC modules. Code-name "Dragon". The SPARCcenter 2000 has *dual* XDbuses. 4 SBus slots, 512 MB memory, and two CPU modules per motherboard. 20 motherboards max. Uses 2 MB cache on the CPU modules; 1 MB per XDbus. 50 MHz CPU. SPARCcenter 1000: Single XDbus design, curious L-shaped motherboards. Three SBus slots, on-board FSBE, 512 MB, 2 CPU modules per motherboard. 4 motherboards total, or a disk tray with 4 535 MB 1" high 3.5" disks. 50 MHz CPU. Codename was "Scorpion" (a small dragon :-) Sun-386i: 386i/150 Used Intel 386 processor at 20 MHz (?). No cache. Bus was what is today known as ISA. Code-named "Roadrunner". 386i/250 Faster model. 25 MHz, 64 kB cache (?). The frame buffer for these was *not* on the ISA bus. ----------------------------------- More Sun CPU info: Sun3 Configurations 3/150 3/50 3/60 3/80 3/160 __________________________________________________________________________ PROCESSOR CPU MC68020 MC68020 MC68030 MC68020 CPU (clock) 15 20 20 16.67 FPC MC68881 MC68881 MC68882 MC68881 MMU Sun-3 Sun-3 68030 on-chip Sun-3 Virtual Mem 256Mb 256Mb 4Gb 256Mb Hard.

[please fill in details on older monitors] Monitors in general come in two flavors: ECL or analog (video-level). All color monitors are analog, as are newer monochrome monitors. Older monochrome monitors (pre-Sparcstation) were ECL. ---------------------------------------------------------------------- Section 5: Misc. questions Can I put 4MB SIMMs in a 3/80? If you have v3.02 or later of the boot proms you can install 40MB. Install 4M x 80ns SIMMS in the low order memory slots (1+5, 3+7) and 1M x 80ns SIMMS in the remaining slots, for a total of 8 ea. 4 MB and 8 ea. 1 MB SIMMS = 40 MB. If you have earlier versions of the proms you are stuck at 16 MB unless you can get a Sun F/E to upgrade them. Rom v3.0.2 has known problems with booting from QIC-150 tape drives. ---------------------------------------------------------------------- Keyboard info: What do the DIP switches underneath the Type 4 and 5 keyboards do? There are several different layouts for the Type 4 and Type 5 keyboards, for different countries, as well as for the Magical Land of UNIX :-) (the Type 5 has, in addition to the various national layouts, a "UNIX layout" which puts Control and Esc, at least, where God intended them to be :-) :-) :-)). So that the OS/window system can correctly set up its tables for mapping raw keystation codes to key "identifiers", the keyboard can be sent a command asking what layout it has; it will send back a reply indicating the "layout code" for its layout. The KIOCLAYOUT "ioctl" (see KB(4M) in the SunOS 4.1[.x] documentation or "kb(7)" in the SunOS 5.x documentation) can be used by a program to cause the command to be sent to the keyboard and its result obtained. The keyboard layout is specified by 6 of the 8 DIP switches, on a Type 4, as I remember (I think it's also 6 of 8 on the Type 5). The DIP switch on the other end of the switch pack, on a Type 4, can be set to cause the microprocessor in the keyboard to report that it is a Type 3 keyboard, for the benefit of old PROMs or old OSes that don't know about Type 4 keyboards; that switch may do that on a Type 5 as well. Type 5's report that they're Type 4's; they're just set to have different layout codes. To see what the layout code is for a given layout, check out the files in "/usr/share/lib/keytables"; a file with the name "layout_XX" is for a keyboard with a layout code of hex XX. On a Type 4, as I remember from the keyboard spec, the one remaining switch does nothing; dunno what it does on a Type 5. On the Type 4, as I remember, if you have the bottom row of the keyboard toward you and the keys pointing down, the leftmost switch is the "Type 3 vs. Type 4" switch, and the 6 on the right are the layout switches; dunno which switches are which on the Type 5. (NOTE: the UNIX-layout keyboard doesn't have its own layout code; instead, I suspect the switch-to-keystation translation map in its microprocessor is different from that for other Type 5's, so that it looks to the software like, I think, a US-layout keyboard.) ---------------------------------------------------------------------- Philips monochrome monitor repair: Components likely to fail: the flyback transformer - this was available from SUN, or from Dyn Service Network in San Jose, CA for about $65 to $85 capacitor C-209 (replace with 10uf tantulum, 35-50v) capacitor C-207 (rep. w. temperature-stable 1000pf (.001ufd) capacitor) All the following capacitors have failed at one time or another on various monitors: C205 C412 C209 C401 C315 C318 C421 (increase voltage rating to 63V) R215,R216 470 ohm vitreous coated wirewound resistors run very hot and have split. They get very delicate and may fail if bumped. ---------------------------------------------------------------------- Toasted serial ports on 3/60s: There are two rs-232 UARTS on the motherboard. One for the keyboard/mouse and one for the two serial ports. On my machine these turned out to be Zilog Z85C008PSC chips. These chips are socketed, and occupy U400 and U401. However, the chips more likely to be fried are the driver chips. These chips are right behind the serial ports on the motherboard, and are labeled in the following way on the bottom of the motherboard: U409 (26LS29) U411 (26LS29) U406 (26LS32) U413 (26LS32) U407 (26LS32) If replacing these chips doesn't help matters, the capacitors near these chips (U412) are also prone to failure. Additionally, there is a resistor pack for each port (R401 & R402) that can be suspect. ---------------------------------------------------------------------- [please add more (relevant, frequently-asked) questions.] ---------------------------------------------------------------------- Section X: For more info... The definitive published information on Sun hardware is the Sun Field Engineer (FE) Handbook, SunExpress part number FE-HNBD-1. SunExpress lists it at $500.00 (US). Call 1-800-USE-SUNX. If this 800 number does not work for you, you are probably outside the area that SunExpress is allowed to sell into, and you should contact your local Sun rep instead.
