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?
Any of you guys have advice on how to get a grip on the weirdnesses of these
chips, when what I'm used to is 8080/8085/z80 assembler?
