4/3xx CPU VME 8M

 25MHz CY7C601, TI8847, Sun-4 MMU with 16 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: a SCSI-2
  connector; an Ethernet connector; four serial ports (D, C, B, and A from left
  to right (top/bottom)), of which A seems to be DB25 and B-D DB9; a keyboard
  connector; eight LEDs (bit 0 to the left/top); and a switch to toggle between
  Diagnostic and Normal modes.

  component side up and connector edge toward you.

 Memory is in the form of up to eight 1M or 4M x 9 30-pin SIMMs in two banks in
  the far right, U1300-U1307 from nearest to farthest.  The nearer four are
  bank 0, bytes 0-3, and the farther four are bank 1, bytes 0-3. Nearby jumper
  J1900 controls whether the SIMMs are 1M or 4M.  The 1M SIMMs are 501-1408,
  501-1466 (same as 4/1xx), 501-1544, 501-1565, and 501-1697. The 4M SIMMs are
  501-1682 and 501-1739.  4M SIMMs are "not supported on the Sun-4/330 CPU" and
  require boot PROM version 3.0.3 or later.

 Additional features of interest: the boot PROMs are in a group in the near
  left, with U2101, U2103, U2102, and U2100 in that order clockwise from the
  far left.  The IDPROM is in the near right corner at location U2202.  The
  time-of-day/NVRAM chip is in the middle of the left edge, at location U2200.
  There is a large jumper bock J2000 in the far left (internal SCSI
  connector?).  The P4 connector is by the SIMMs, just nearer.  The SCSI fuse
  F3200 and Ethernet fuse F3100 are by the SCSI and Ethernet connectors
  respectively.  The keyboard fuse F0300 is by the LEDs.  All three fuses are
  150-1174, 2A.

 Note that the CPU is permanently set for type-2 Ethernet transceivers.

 Note that 501-1316-04 and later is required to use the ISP-80 or FDDI
  controllers, and to run LISP software.  Also, 501-1316-03 or later is
  required to use the cg5 framebuffer.

 Note that boot PROM version 3.0 or later is required to boot from the 60M
  quarter-inch tape drive in the Mass Storage Subsystem.  Boot PROM version
  3.0.1 or later is required to boot from a tape drive on a secpmd SCSI
  controller.  Boot PROM version 3.0.3 or later is required to use 4M SIMMs.
  Boot PROM version 4.1.1 or later is required when the 501-1537(1538) VX(MVX)
  Visualization Accelerator is used as the console.

 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 J2302,
  J2303, J2502, and J2503.

 Power requirements are +5V @ 17.5A, +12V @ 0.2A, and -12V @ 0.2A.
