disassemble the Western Digital WD1000 and WD1001 firmware, and the
Zendex ZX-203 firmware, I've become curious as to what other products
used the SMS300/8X300/8X305. Does anyone know of any?
My Durango 900 series machine uses one for the hard disk controller on
what is about the size of an S100 card, but a little smaller. It fits
in the expansion area just in back of the floppy drives and drives an
ST506-interface drive.
The previous model used a Shugart SA4000 external hard drive and a card
with an Intel 8291 and 8292 to implement a GPIB link. The controller
itself is full of TTL and matches the footprint of the SA4000.
Microsystems Consultant in Sunnyvale designed it.
There was a floppy controller in the Signetics Bipolar 8X300 line. It's
in the Signetics Bipolar Microcomputer databook.
