Hello, I'm trying to understand the intriguing Panasonic HHC. Does somebody have additional technical information beside the contents of the User's Manual? I'm particularlly searching for the SnapFORTH ROM image and manual, any hardware schematics, and the expansion connector pinout. I'm also trying to understand the Cassette Tape audio file format. Any information on that will be nice too. Ricardo P.S. Sorry about my limited English vocabulary and eventual (unnoticed) lack of politeness. I'm from Brazil and not English native.
