Almost on topic - Cassette I/O

Howdy to a fellow Canuck no doubt digging the long underwear out of the closet in preparation for winter...

Might have something for ya; was just having one last look through some old Byte mags pulling out Cromemco ads before tossing 'em, and in July '76 there is a construction article for a fast cassette interface. Can scan it for ya if you're interested. Might also be able to find some others, was a popular project in those days. Can also ship you a Burroughs L series digital cassette drive (with some docs) if you're up to the challenge of interfacing it :) Also have tech info on some old computers (e.g. RS M100, AIM65) using cassette I/O.

See on your web site you're also looking for PPT stuff; might even have something for ya in that department (Toronto area, though).

While on the subject, anybody interested in an SwTPc AC-30 cassette interface? Just happen to have one; in fact, the reason I remembered that issue of Byte is 'cause the AC-30 is advertised on the inside front cover.

Subject: Almost on topic - Cassette I/O

I am building a FPGA ( Field programmable gate array ) computer
in the style of the early computers that had a front panel and
TTY for I/O. While I don't have have a front panel working the
Hardware serial bootstrap does work on my prototype. Since I
have a few LOGIC cells left in my FPGA to play with I was
thinking adding a cassette interface. Does anybody know of
schematics on the web that I can get ideas from.

Now with schematics.
