501-1381
4/4xx CPU VME
33MHz CY7C601, TI8847 (?), MMU with 64 hardware contexts. VME bus interface.
P4 connector.
From left to right, with component side up and connector edge toward you
(normal top edge at left), the rear edge of the board has: two serial
connectors (ports A and B from left to right (top/bottom)); a keyboard
connector; an Ethernet connector; a switch to toggle between Normal and
Diagnostic modes; eight LEDs (bit 0 to th left/top); and a reset switch.
There are a variety of jumper blocks. Locations below are given with
component side up and connector edge toward you.

Used for ATE. JUMPED
J0201 (single jumper in middle near edge)
Used for ATE. JUMPED
J0300 (block in near right corner, pin 1 nearest)
1-2 jump if FPC is present JUMPED
3-4 unjumped if FPC is present UNJUMPED
5-6 avoid a trap when I-flush instruction executed JUMPED
7-8 FPC chaining (only if FPC present) UNJUMPED
J0705 (10-pin block in far right)

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.
