Hi,
Ive been following this, and maybe I can help. Im a professional PCB
layout guy in my day job. With a schematic and a reasonable resolution
jpeg of both sides (I doubt there was mych multylayer back then) I could
reconstruct the design fairly quickly. Nobody is really going to want to
go down the road of taking a picture and turning it into a gerber, it just
wont work. Id just input the schematic, duplicate the ref des for all
parts, to get the netlist, eyeball the jpeg for placement and throw it at
the autorouter.
Whats on your top 10 list?
(S-100)
CPU card
Dazzler
Byte Blaster
Async card
disk controller card
I could knock those out in a week or two.
Randy

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!
