Hi guys,
The USB floppy reader project is back on track as of about an hour
ago. I've found a distributor who has a couple of Altera FPGAs in
stock, and although it'll take a few days for them to arrive from
Belgium, they were quite happy to sell me just five of them. For
anyone that wants to look up the datasheet, they're Altera Cyclone II
devices, p/n EP2C8T144C8N. Cost was ?11.58 +VAT.
I wish I had one of these right now. Someone who has UniPlus Unix for
the Lisa dug up his disks for it and is attempting to make images of
them. They are copy-protected, but worse yet, they've been stored in a
non-climate controlled garage, and some of them are unreadable.
If it would be possible to add a way to grab the analog waves (digitized
to 8 bits?), in addition to the pulse-gap mode, it would help a bit too
in terms of data recovery for weaker disk areas.
This would have come in very handy for the UniPlus disks... I'd
certainly buy one of these if fully built right now for $75.
