    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...

    Yep, I understand that, but why populate the 512K/1M jumper if all chips
    are soldered in on the "9151" sample? Welp, it may come handy if there's
    a defect in the top 512K...
