The OS technically is BASIC. I have no floppy/datasette devices yet so I cannot save, but I can save on my other computers and retype the valuable code. This BASIC isn't very basic crap, I said a pun on a serious forum, but it apparently lets you use the 3 SID voices, sprites, and.... Anything the 38911 BASIC bytes can hold, really. Anybody have and sauce source code or ideas.... Or anything relevant to old CPUs? I'm probably getting a 51/4 inch diskette reader sometime.
