I've
had a few of the Adaptec boards, including one mounted in
an Atari SH-204 hard disk, converting from the ST's interface to the
MFM
drive mounted in the enclosure.
Hm, very interesting! I wonder what model they used? Like I said
before,
most of the early SCSI boards from Adaptec (and most of the other mfr's
as well at that time) were only partial SCSI implementations.
Ah, well, mebbe I stuck my foot in my mouth-- the ST did have a SCSI
interface, didn't it? Or was it yet another whacko custom thingie . .
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.
