D'oh! I feel stupid. Don't ask me why I read 65xx with you asked about
805x. I've been writing 805x for about 15 years, and I've never run across
one. I've though about writing one from time to time, but never got around
to it. Since I usually have a pretty tight embedded system, I use all host
side tools. If you write one, I'd be interested in looking at it.
I have seen 6502/6800 style embedded assemblers. Never used them. I have
not used
a 805x so I don't know the Instruction set for it so I don't know how
easy it would
be to write one. Most user side tools are from the early days of $1000 8
bit computers when you only had ONE computer.Here is some printable
Instruction Set Cards for many cpu's other than 805x. Also many early
computers like the PDP-8,8080 had a instruction set that let you code
directly in octal numbers.
