I have a sparsely-populated S100 board carrying an INS2651 chip and a
50-pin header. There's little other clue as to the function of this
board. I'm guessing it's a floppy drive interface of some sort, but the
maker and model have me guessing. I've never heard of "Alloy Eng.
C.P.D.". What appears to be a model number is "DWG NO. 100055 REV. H".
Does anyone know anything helpful about this?

Alloy Engineering was mostly know for its tape backup systems. Since
the 2651 is a USART, I suspect that this is what your board was used
for--probably an early QIC system. December 1980, IEEE Computer
shows a model DS-100 controller for S-100, driving a 17.4 MB 1/4"
cartridge drive.
Is this the widget?

See the "DS-100" at the top?

This is all guesswork, but it's probably a QIC-36 interface. The
thing is still listed on media selection sales lists as taking
DC300XL tapes--very likely a Wangtek 5000E. Herb Johnson claims to
have a manual for the Alloy unit, so you might ask him about it.
Software, on the other hand, may be a bit difficult to come by.

Interesting. This card is for sale, in case anyone is interested. By the
way, where can one get DC300XL tapes nowadays? Google gets me lots of
hits for degaussers and cleaning tapes, but no media.

If the drive was indeed a 5000E, it's supposed to be able to tell the
difference between DC300XL and DC600XL media automagically and adjust
write current. So you might try a DC600XL tape if you get the thing
going--they shouldn't be hard to find.

I'd have to find a drive first, then fiddle around with getting it
working. I don't have a working S100 system.
