Reading this brought a smile to my face:
Motivation: for Making LoseThos:
1986: I had a book called, "Mapping the Commodore 64," when I was a teenager and it told what
every memory location did. I hooked-up Radio Shack photo-transistors to my paddle-port and
relays to another port.
I think I spent more time with my trusty copy of Mapping the Commodore 64
than I have with any other book I've owned with the possible exception of Lord of the Rings
. That book, plus a subscription to TPUG's marvelous Transactor
magazine, and I was ready to do anything with my C64. Boy could you put that little "box of chips" to a lot of different uses. My biggie was a program I wrote (in FORTH supplemented with some assembly code) that let you use an inexpensive Casio keyboard to play musical notes directly through the SID chip. I later adapted it so that you could also input them into the Kawasaki Synthesizer
program for playback.
Glad to see the spirit and passion are still alive. You have to admire anyone with the desire to build a small but usable OS from scratch for no other reason that the pure fum of doing so. Brings back memories it does.
