        The plot thickens...I've just opened up the SH-204 and found
the following:

        - Atari ST 19pin input to circuit card #1 (Atari Host
Adapter, part# C026266)
        - 50pin output from above board to card #2 (Atari part#
C070733) which contains the following 3 Adaptec chips: AIC-010,
AIC-250, and AIC-300.
        - standard dual MFM cable output , plus power, to a Tandon
TM-262 hard disk.

        All of this, plus PSU, in the SH-204 shoebox case. No
Adaptec part# on the 2nd board though.
