Hello,
I need some help about the board Model 5400, ASSY00060-13 REV T urgently. Can you send me
some technical documents(if you have any) about this board. Do you have any information
about that if I can get an extra board from the producer or not ?

Not many posts from Turkey on this list, so welcome!
Can you tell us who made the board, what piece of equipment it's from
and what it does?
Cheers,
Chuck

Hmm. Possibly an OMTI 5400 disk/tape/floppy to SCSI bridge board? If so, Al's
got a scan of the manual up on Bitsavers:
http://www.bitsavers.org/pdf/sms/OMTI_5x00.pdf
... from what I remember the hard disk portion of the controllers is
compatible across the whole range - so if you just need to drive a hard disk
with it, then any OMTI board will do (it doesn't have to be a 5400). Lots of
systems used to use these boards (and so are a possible source of spares), but
I doubt they've been produced for quite a few years :-)

Definitely not compatible throughout the whole range, if that's what
this is. Some of these were RLL 2,7 drive interfaces. I've got two.

Hmm, I'd forgotten they did RLL ones too - were they the 7xxx series? I'm
pretty sure all 5xxx boards are interchangeable anyway (subject to them
providing the required interfaces), and I *think* they're supposed to be
compatible with an earlier non-5xxx board.
I've had various systems using the 5xxx boards, but I don't think I've ever
run across any of the others fitted to anything.

I think some of the 7xxx ones were used by at least one third-party
vendor in hard disks for the early Macs. At least I recall the tech
support guy at SMS saying "Oh, you've got the Mac PROMs". I did a
design using one of these that interfaced an MFM drive to the Atari
ST's ACSI port. Worked pretty well, but I despised the shoddy
construction of the ST.
