A friend I work with donated the following book to my collection today:
VIC-20 Interfacing Blue Book, by V.J. Georgiou
Anyone seen this before? It is an incredibly neat book on hardware
projects for the VIC-20, including such things as Liquid Level Sensor,
ram expansion cards, eprom programmer for micromon, ring detector and
lots more. It is overall a superb text. If you would like more info,
let me know. I'm not interested in getting rid of the book but would be
willing to share via scans or photocopies. ;)
Cheers,
Dan
