I cobbled together a breadboard of TTL (mostly
latches/counters and
muxes) which, with suitable software support on the host, lets me
read ROMs via a parallel port. [...]
That would be of interest to me.
Okay, I'll see if I can't put together a schematic.
On ftp.rodents.montreal.qc.ca there's a directory
/mouse/misc/schematics/ that contains, among other things,
parport-rom-reader.pbm and parport-rom-reader.txt (the former is the
schematic proper; the latter, accompanying text).
If you'd like it but can't handle PBM files, let me know what you can
handle and I'll see what I can do.
