I have tracked down the author of the SFX Sound Expander design. Here's an email she wrote about the history of the SFX series products.

Nobody had done a sound card for PC until then (certainly Apple et al) - 1987, but if anyone want to correct me that is fine. I checked with the original company Richard Watts Associates where I was contracted to last year to verify this. Feeel free to pass this email on.

He's interested in the area himself and was wondering if you know who designed this cartridge: http://www.funet.fi/pub/cbm/schematics/cartridges/c64/sfx/sfx-sch.gif Other relevant links: http://www.floodgap.com/retrobits/ckb/secret/sfx.html http://www.floodgap.com/retrobits/ckb/secret/cbm-sfx-better.jpg http://www.floodgap.com/retrobits/ckb/secret/cbm-sfx-int-better.jpg Thanks, James -- This email was forwarded via the University of Cambridge alumni email system Visit http://cantab.net/ to update your forwarding details Message was sent through the cbm-hackers mailing list
