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?
