SCSI-IDE-CF Experiment

[pitz <pitz.wong@gmail.com>]

I was testing a SCSI-IDE-CompactFlash setup for a different platform a
few weeks back.  On a whim, I thought I'd bring out the Apple High
Speed SCSI card to test a similar setup on a IIgs.  I used a SCSI-IDE
adapter, a cheap IDE-CF adapter, and a regular 128MB CF card.

System 6.0.1 boots fine from the first partition in my CF card -- this
was the same CF card taken from a working CFFA setup.  It will not see
the other partitions in the CF card, since I think SCSI and IDE
partitions are set up differently.  And I didn't want to re-format my
CF card because I still use it with my CFFA.

I wasn't planning on any wiring or soldering work, so I had to use an
external SCSI case to hook up the adapters.  The adapters use regular
molex connectors for power (IIRC, Henry used to sell/modify IIgs power
supplies to provide additional connectors).  The other platform (NeXT)
I was working on already had this molex connector.  The SCSI-IDE
adapter has a regular 50-pin SCSI connector.

Interestingly, the SCSI-IDE-CF setup seems to boot up slower than my
external SCSI drive (this observation may not be entirely correct,
since I only tried, and not with full certainty, to make my SCSI HD
software setup the same as the SCSI-IDE-CF software setup).  A faster
CF card might also make a difference (unfortunately, I did not try
this).
