- Spartan is a, build it yourself, SCSI interface for the Amiga 500
- or Amiga 1000 which was featured recently in the AC TECH magazine,
- Vol.2, Num.1, 1992. My only association with it is that I built
- one and am very happy with it.

-
- Included in the article was a disk containing a low level formater,
- device driver, sample mountlists, and other info. All those files are
- included in the archive.
-
-
- In addition, I have included two other files which are replacements for
- the low level format and test programs. Those original programs would
- not work correctly on my system. My versions are slightly modified in
- that a delay is inserted immediatley after the scsi SEL signal is
- de-asserted. Those new files are in the directory named NewSformat.

- The design is not auto config or auto boot. It is known to work with
- Seagate, Quantum, Maxtor, Adaptec, Sysquest, and probably most others
- (These are the ones I've been told do work). I had trouble with a
- 90 meg Fujitsu drive that is firmware configured for Macintosh. Someone
- else apparently had trouble with a Rodyne drive. (My Maxtor works
- fine)
-
- I ordered the bd and 5380 chip from the designer and bought the rest of
- the parts through digi-key. Total cost was just under $50.

- The text of the article is not in the uploaded files. I would suggest
- asking Paul Harker to email you the ascii portion or get the magazine
- if you can. Failing that, I will mail a photocopy if you send a self
- addressed stamped envelope to me.

-
- There are reported problems with copying large files across partitions on
- some IBM type drives using an Adaptek adapter. When this happens, the
- drive has to be reformatted. I would suggest using only one partition
- with these drives.
