Birdsall (jwbirdsa@picarefy.com) PART III ======== BOARDS BOARDS ====== This section covers the various circuit boards which make up or are used with Sun systems. This includes: CPU boards/motherboards; memory boards; video boards and video accelerator boards; SCSI controller boards; non-SCSI disk controller boards such as SMD and IPI controllers and boards used to connect non-SCSI disks to SCSI busses; non-SCSI tape controller boards such as those used with 9-track tapes; Ethernet boards (boards for systems where Ethernet is not integrated into the CPU/motherboard and boards providing second, third, etc. network connections for systems with integrated Ethernet) and boards for other networks such as Token-Ring and FDDI; communication boards, including serial, parallel, synchronous, and X.25 boards; floating-point and other system accelerator boards; cardcage backplanes; and boards not covered by the categories above. The first subsection is a brief listing of boards described in the rest of this section, sorted by bus type (Multibus, VME, P4, ISA, SBus, MBus, XDBus, SCSI, None, Unknown).

memory. Multibus interface. The CPU board is entirely concealed within the chassis. On one long edge, it has Multibus card-edge connectors. On the other long edge, from top to bottom, it has: a header connector for the Sun-1 parallel keyboard and mouse, eight LEDs, and a 50-pin header connector (J1) for two serial ports. The LEDs display the usual sort of test cycling at power-up. Unlike later models, they do not simply blink or cylon while the OS is running; instead, they display all sorts of patterns, possibly in response to bus activity (?). Jumper information: J200 Crystal shunt JUMPED by default Located by crystal at D1. Removed for A.T.E. testing, installed for normal operation. J400 EPROM select JUMPED by default Located by EPROMs at D10. 1-2 selects 27128 EPROMs (default) 3-4 selects 27256 EPROMs J700 Bus priority on serial arbitration UNJUMPED by default Located by bus connectors. J701 Common bus request arbiter UNJUMPED by default Located by bus connectors. If the CPU board is used in conjunction with a Multibus DMA board (such as a disk or tape controller) that does NOT support the Common Bus Request (CBRQ), the CPU board must be configured such that it gives up the Multibus after every Multibus cycle, by jumping J701. This also causes three additional wait states for each Multibus access. When this jumper is unjumped, the CPU board retains bus mastership until a lower priority master requests it by asserting CBRQ. Following a CBRQ, the CPU board yields mastership for at least one cycle. Certain machine configurations (especially those with color) will be much slower if this jumper is jumped. J702 Enables the CCLK on P1 JUMPED by default Located by bus connectors. J703 Enables the BCLK on P1 JUMPED by default Located by bus connectors. J801 Selects +5V for the parallel mouse UNJUMPED by default Located by J2 header connector. Used only in 100U configurations (?). The two serial ports on J1 are usually labelled SIO-A and SIO-B on the back of the machine and appear as /dev/ttya and /dev/ttyb under SunOS. The documented maximum output speed is 19200 bps. All ports are wired DTE and are compatible with both RS-232C and RS-423, using Zilog Z8530A dual UART chips. The pinout of J1 is: 3 TxD-A 14 DTR-A 33 DD-B 4 DB-A 15 DCD-A 34 CTS-B 5 RxD-A 22 DA-A 36 DSR-B 7 RTS-A 24 BSY-A 38 GND-B 8 DD-A 28 TxD-B 39 DTR-B 9 CTS-A 29 DB-B 40 DCD-B 11 DSR-A 30 RxD-B 47 DA-B 13 GND-A 32 RTS-B 49 BSY-B Power requirements are +5V @ 6A. 501-1051 2/120,2/170 CPU Multibus 10MHz 68010, no floating point chip, MMU, no on-board memory.

The P4 connector is in the middle right, by the divider. The IDPROM is nearer, at location U805. The keyboard fuse F1000 is near the keyboard connector at grid C2 and the Ethernet fuse F1800 is near the Ethernet connector at grid F2. Note that 501-1199 boards must be 501-1199-11 or later, and 501-1237 boards 501-1237-11 or later to use a type-4 keyboard. Note that the 501-1384 FPU2 is supported only on 501-1512/1513/ 1514/1515/1516/1517. Note that for the Ethernet autosense to operate, more than 30mA must be present on the +12V return. Note that boot ROM version 3.0 or later is required to use the P4 cgsix color framebuffer (501-1374/1505/1532) as the console.

No bus interface, but a P4 connector for a color video board or other option -- not the same as the P4 in the 3/80 or any SPARC model. From left to right, the back edge of the board has: a female DB15 keyboard/mouse connector; eight LEDs (bit 0 to the right); a switch to toggle between Normal and Diagnostics modes; a BNC thin Ethernet connector; a female DB15 AUI Ethernet connector; two female DB25 serial port connectors (ports B and A from left to right); a female D50 SCSI port connector; and a female DB9 monochrome video connector (for those models with a monochrome framebuffer). Above these are an upper row of cutouts or connectors for color video and other options. Pin 1 is usually in the upper right corner of all connectors. Unconnected pins are not listed.

On power up, it cycles through the tests in the chart above, then boots Unix. If LED 7 (10000000) lights up while the tests are being performed, it indicates that the test failed. If LED 6 (01000000) lights up with the tests are being performed, it indicates that an unexpected error (bus error, address error, unexpected interrupt, etc.) occurred during the test. When all tests are finished, LED 5 (00100000) starts blinking to indicate that the ROM monitor is running and/or Unix is booting. If you want the machine to boot normally, set the diagnostics switch to "NORM". If you want extended diagnostics when you power up the system, set the switch to the "DIAG" position. If the switch is set to "DIAG", power-on self-test messages are sent to serial port A at 9600 bps, 8 data bits, one stop bit, no parity, and XON/XOFF flow control.

This can cause a short if another device in the chain is providing termination power! The monochrome video output levels are ECL/TTL. The output can be switched between low resolution (1152 x 900 61.8KHz horizontal sync, 66Hz vertical sync) and high resolution (1600 x 1280) via a jumper in J800.

These SIMMs are part number 501-1239 and are the same kind used in IBM PC clones. Note that some users have experienced problems with three-chip SIMMs (as opposed to nine-chip SIMMs) -- see Misc Q&A #17. The amount of memory seen is controlled by part of J800. There is one jumper block and various points of interest. All locations are given with component side up and connector side toward you.

Note that the video cable must be 530-1539 or 530-1336 and the monitor must be 540-1427 Motorola revision T or later for autoselect to operate. Additional features of interest: the Ethernet fuse is in the far left corner by the 3V battery, at grid J39. The IDPROM is at location U224 (grid I20) in the leftish middle. The boot PROM is at location U300 (grid K8) on the left side in the middle. The 8530 UARTs are also on the left side, toward the near end from the boot PROM. The keyboard fuse is in the near left corner by the keyboard connector at grid K1. The P4A and P4B connectors are on the right side on either side of the middle bar. Note that boot PROM version 1.6 is required to boot from a QIC-24 tape. Boot ROM version 3.0 or later is required to use the P4 cgsix color framebuffer (501-1374/1505/1532) as the console. Power requirements are +5V @ 11/13.5A typical/max, -5.2V @ 0.3/0.5A typical/max, and +12V @ 0.3/0.5A typical/max. (The FE manual lists +5V @ 10.1A for models with framebuffers and 8.9A without, -5V @ 0.7A for models with framebuffers and 0.3A without, and doesn't list +12V at all.) 501-1206 3/2xx CPU VME See 501-1100. 501-1207 3/50 motherboard with FPU Same as 501-1075 except the 68881 is factory-installed. 501-1208 3004 "Carrera" CPU VME 4M (3/75/140/150/160/180) 16.67MHz 68020, 68881, Sun-3 MMU with eight hardware contexts, 4M of onboard memory.

Pin 1 is usually in the upper right corner of all connectors. Unconnected pins are not listed. Jumpers J2501 and J2503 relate to Ethernet. The pinout of the AUI Ethernet connector is: 2 E.COL+ 9 E.COL- 3 E.TxD+ 10 E.TxD- 5 E.RxD+ 12 E.RxD- 6 GND 13 +12V The eight LEDs are used for diagnostic purposes. If you want the machine to boot normally, set the diagnostics switch to "NORM" (labelled "BOOT" on some early versions). If you want extended diagnostics when you power up the system, set the switch to the "DIAG" position. If the switch is set to "DIAG", power-on self-test messages are sent to serial port A. The user reset button invokes a watchdog reset. The result depends on the value at address 0x17 of the EEPROM. (?)

On power up, it cycles through the tests in the chart above, then boots Unix. If LED 7 (10000000) lights up while the tests are being performed, it indicates that the test failed. If LED 6 (01000000) lights up with the tests are being performed, it indicates that an unexpected error (bus error, address error, unexpected interrupt, etc.) occurred during the test. When all tests are finished, LED 5 (00100000) starts blinking to indicate that the ROM monitor is running and/or Unix is booting. If you want the machine to boot normally, set the diagnostics switch to "NORM". If you want extended diagnostics when you power up the system, set the switch to the "DIAG" position. If the switch is set to "DIAG", power-on self-test messages are sent to serial port A at 9600 bps, 8 data bits, one stop bit, no parity, and XON/XOFF flow control.

JUMPED Additional features of interest: the boot PROMs are in a row in the far right, U3501-U3504 from left to right (3-0 respectively). The IDPROM is in the near right at location U1404. The P4 connector is nearer than the boot PROMs. The NVRAM chip is in the near left, by the divider. The keyboard fuse F3701 is in the near left and the Ethernet fuse F3200 in the near middle. Note that pin 25 of the serial ports on the 501-1381 is -5V out. Pin 25 of the serial ports on the 501-1899 is not connected. Note that the 501-1381 is not supported in the 4/470 serial numbers 136Kxxxx and greater. This chassis has two 50-pin SCSI-2 connectors on the rear EMI cover. Note that boot PROM version 3.0 or later is required to support the 501-1721 128M memory board. Boot PROM version 4.1.1 or later is required when the 501-1537(1538) VX(MVX) Visualization Accelerator is used as the console. Note that this board can use P4 cgeight framebuffer 501-1371-04 or later only. Note that SNC 1.2 for Solaris 1.1 requires 501-1381-01 or 501-1899-01. To provide circuit protection to the M+ and M- (+-12V) inputs on the UC5170 serial port liner driver, install fused shunts 150-1669 at locations J3603 and J3604. Power requirements are +5V @ 28.7A, +12V @ 0.1A, and -12V @ 0.1A. 501-1382 4/60 (SPARCstation 1) motherboard <= 501-1382-12 4M w/o FPU >= 501-1382-13 8M w/FPU >= 501-1382-14 8M w/FPU FCC-B 20MHz MB86901A or LSI L64801, Weitek 3170, Sun-4c MMU with 8 hardware contexts. 20MHz SBus, slot 3 is slave-only. From left to right, the rear edge of the board has: a 50-pin SCSI-2 connector; an Ethernet connector; two serial port connectors (ports A and B from left to right); an 8-pin-DIN keyboard/mouse connector; an audio connector; and a headphone connector. Connector pinouts and form factors are not known. Memory consists of up to sixteen 1M (501-1408) or 4M (501-1625 or 501-1739) x 9 30-pin 80 or 100ns SIMMs, in four banks. Banks must be filled in the order 0, 2, 1, 3, and SIMM types may not be mixed within banks.

Additional features of interest: the boot PROM is in the near middle at location U0837. The NVRAM/TOD/ID chip is to the left of the boot PROM at location U089. At the far edge, more or less from left to right, are the power, floppy power, floppy, LED/speaker, and two pairs of internal SCSI and disk power connectors. In the near left corner are the SCSI (U2) and Ethernet (F071) fuses, and the keyboard fuse (F082) is in the rightish near edge. All fuses are 2A, P/N 150-1174. Note that the SPARCstation 1 was first supported in SunOS 4.0.3c. Note that boards 501-1382-08 or later, or 501-1629-10 or later, and SPARC IU 100-1808-02 or later, are required for use with Sun Common LISP, AutoCAD, Cobol, and SunOS 4.1. Note that bug 1047696 in the installation of SunOS 4.1.1 and 4.1.1 Rev B causes trouble when mixing 1M and 4M SIMMs. "Install the 4MB SIMMs in bank 0 when installing miniunix." Note that the 501-1667 Load Board should be installed in systems without disk drives or SBus cards. Note that boot PROM version 2.4 requires at least SunOS 4.1.1. Power requirements with eight 1M SIMMs are +5V @ 2.5A. 501-1401 3/80 motherboard 20MHz 68030 and 68882, 68030 on-chip MMU. P4 connector for video. From left to right, the rear edge of the board has: a 50-pin SCSI-2 connector; an Ethernet connector; two serial port connectors (ports B and A from left to right, port B appears to be DB9 while A is DB25); a parallel port; and an 8-pin-DIN keyboard/mouse connector. Connector pinouts and form factors are not known. The sixteen SIMM slots are arranged in four groups of four. Electrically, there are four "banks," each of which is composed of one slot from each group: Back of machine (nearest SBus connectors) bits -------U0606------ 0 0 --------U0604------- bits 8-15 16-23 -------U0806------ 2 2 --------U0804------- -------U0703------ 1 1 --------U0701------- -------U0903------ 3 3 --------U0901------- bits -------U0605------ 0 0 --------U0603------- bits 0-7 24-31 -------U0805------ 2 2 --------U0803------- -------U0702------ 1 1 --------U0700------- -------U0902------ 3 3 --------U0900------- Front of machine (nearest disk connectors) Banks must be filled in order (0 through 3), and SIMM sizes (1M or 4M) must not be mixed with in a bank. Only 1M SIMMs (501-1408) are officially documented; 4M SIMMs can be used with boot PROM version 3.0.2 and later. There are a variety of jumpers. All locations are given with component side up and connector side toward you.

Additional features of interest: the boot PROM is in the near right, at location U0204 (grid J3 C0). The NVRAM is also in the near right, at location U0205 (grid J7 B3). The SCSI fuse F1400 (see below) is in the near left corner, beside the Ethernet fuse F1500. The keyboard fuse F0400 is in the near right corner. The power supply connector, the floppy control/data connector, and the floppy power connector are in the far left corner. Near the far edge are (from left to right) the LED/speaker connector, and two pairs of disk control/data (SCSI) and disk power connectors. The P4 connector is in the far right. Note that pin 38 of the SCSI port is fused (F1400) with a 1.5A fuse, P/N 150-1383. The Ethernet and keyboard fuses (F1500 and F0400) are 2A, P/N 150-1174. Note that 501-1401-07 and earlier boards do not meet the P4 bus specification. CPU boards 501-1401-10 and later and 501-1650 have FCC-A approval. "Use SCSI terminator 150-1537."
