Were two PCB layouts? Earlier one had a jumper "JU8 CLK" near the center
osc. The later card does not have this osc and no JU8.

Hmm, the box shows even an earlier version with through-hole PALs and
what not:

A pre-production sample? No clue...

While transporting a fully-armed attack Brittany to a live-fire range,
there were at least two Dot Clock Generators, ICS1394 [35 MHz] and
ICS1494 [85 MHz]

I'm sure there were more PCB versions...

Note the blue ZIPP sockets, U10,12,14,16

The video controller is fabbed by Toshiba.

Probably a gate array.

One half of the memory is socketed even on the later boards it seems.
(this explains the memory size jumper)

Actually, the "9151" board seems to have all DRAMs soldered in. Yet the
jumper header is still populated. Hmm...

You could get 512K with 4 sockets, or a 1MB with all positions filled
with soldered ZIPPs.

The Model 90 could come 8 sockets, 4/4, and 8 soldered.

ATI chose to interleave socket/soldered...
