501-8064
4/E (SPARCengine 1) CPU VME 16M w/Weitek
VME bus interface, 6U form factor. One SBus slot.
From left to right with component side up and connector side nearest you
(normal top edge at left), the rear edge of the board has: a 50-pin SCSI-2
connector; an Ethernet connector; a keyboard/mouse connector; a serial port
connector (port B, apparently DB9); eight LEDs (bit 0 to the left/top); a
reset switch; and another serial port connector (port A, apparently DB9).
Connector pinouts and form factors are unknown.
There are a variety of jumper blocks. All locations are given with component
side up and connector side toward you.
J0301 (single jumper in middle)
Jump to enable 20MHz clock. JUMPED
J0801 (3-pin jumper in far middle)
1-2 Use 4M parity memory JUMPED
2-3 Disable 4M parity memory
J1701 (single jumper in middle far edge)
Jump if CPU is installed in VME slot 1. JUMPED
Additional features of interest: the boot PROM is on a daughtercard in the
near left. The keyboard fuse F1101 and Ethernet fuse F0901 are near the
keyboard connector and are not field replaceable. The SBus connector is
along the far edge, by one of the VME connectors.
Note that boot PROM version 1.4 does not support SunOS 4.1e, but versions 1.5
and 1.6 do.
Note that boot PROM version 1.6 and daughtercard 500-8013-05 are installed on
CPU 501-8035-12. This daughtercard is required if a customer-supplied PROM
is used with the 1.6 boot PROM; customer-supplied PROMs will not function on
daughter cards 500-8013-04 or below, even if 1.6 boot PROMs are installed.
Power requirements are +5V @ 5A, +12V @ 0.1A, and -12V @ 0.1A.
