Hi,
All those S-100 boards definitely sound interesting but here is a twist for
something I think would be highly useful for recovering data from vintage
computers using generic PCs.
How about a PCI floppy controller board? Maybe with some supplementary
logic to allow raw track reads? Possibly a BIOS to boot from? An external
floppy drive connector?
Just wondering how complicated such a thing would be. Thanks!
Hi
It would be relatively easy if you did most of the work in a DSP chip.
For the floppy end, you need a parallel port to read status and
write controls.
For reading raw data, a 7474 flipflop, an adjustable clock
and a DSP chip, such as a ADSP2118 or similar.
Then you'd need a bus interface to the PCI bus.
