Back when I first got my IMSAI 8080, I bought 3 books from Scelbi, for monitor, editor and assembler, which were essentially source code and both octal & hex listings. I had to manually toggle in the octal for the monitor and then save to cassette, just to get things going. I later did the same with their "SCELBAL" BASIC interpreter, but since I had the monitory running then, I was able to type, rather than toggle in the octal listing. Later on, I had the editor and assembler working, so I could then type in the source code. I also built that computer from a box full of parts. Back then, you really knew your computer inside, out. :-)
I heard of those things. Once I built a 1 bit adder module (with carry in/out) with relays, just for fun. That's the deeper I got to the bones. Software with switches... No! :-) -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
