The Apple II monitor had a complete commented listing in the back of the
book that came with it. (for a II it was the "red book", II+'s come with
a listing too at the end of the hardware manual.)
I'm sure Rich Cini's site has the source to the KIM-1 monitor.

Well, if you've got some of the chips and want to do some wire-wrapping
or soldering, you can buy the additional chips you need and
put one together without a lot of effort. Schematics
on the web at Rich Cini's site.

I always thought that'd be a nifty machine to get a hold of and play with,
but never did, somehow. Last one I saw for sale was way up there in price,
not something I was gonna spend... Speaking of 6502s, I happen to have a whole
bunch of those, and some
6510s, and 6522s and 6526s, and perhaps even some 6551 (?) UARTs too.
Anybody have anything particularly nifty that these would be good for? I
kinda like Garth Wilson's workbench computer, and definitely don't want
to go the route that some have gone (found on the web) where multiple
floppy drives and writing a bloody dos for it and all that sort of thing
get involved. Anybody know of some simple monitor-type software that's
out there?
How adaptable is the KIM-1 monitor? IIRC it had both the keypad and
a TTY mode where it would use the UART. I used KIM-1's but never got too
much into poking around everything the monitor could do/did do. There was also
the Apple II monitor with its built-in disassembler
(and miniassembler with the right INTBASIC toolkit ROM, right?) It'll have
a lot of hooks into the Apple II video range but if those are somehow
rip-outable then it might be a start (worse comes to worse, you know that
you can use the PR# and IN# hooks for character in and out). And
also in the toolkit ROM was SWEET-16... Wow, going back a couple
of decades, that was fun back then!
I remember some magazine article dealing with Sweet-16, in Byte? Been a long
time, anyhow. That stuff built in ain't that big a deal, my thinking is
more toward doing assembly and such on some other box and downloading it.
Big question for either of these, though, is source available?
