    Now that we have actual pictures to refer to, I started placing NODEM
    and Ethernet on SCSI stuff on it.

    Foundt most of it, but the AIC-011L and the AIC 290L datasheets elude me.

    There is U10 Adaptec NODEM 419404-00A, I'm guessing it's a masked 8051
    -12. Can't confirm that.

    U14 may be the pads for a 28 pin DIP 16K EPROM for on-board Nodem system firmware (for connection of disketteless devices)

    16v x 2A = 32watts you're missing 0.5A Major

    Something isn't right with this link, wonder what "404" means...
