I'd be interested. what does it require to run?
Allison
Wonderfull Allison, thanks! There's a win-32 console binary (it's small)
for 95/98/NT or a single .cpp source file that shouldn't be too hard to
recompile anywhere else.
Dump machine code in with the m! command (for ex: " m! 0 1525c4" will dump
INC (r5); DEC (r5); NOP into 'ram' starting at address 0 (A write cursor
allows continuations in entry, another "m! c4c4c4" will write 3 NOP's
starting a address 3 using the above example) and then three 't' commands
will single-step execute the instructions (or a single "t 3" would have
too). 'r' dumps registers at any point. and "m? address [count]" looks
at
memory.
Thanks for the help!

I'll add a nice GUI to it
and
clean up the
code that I'm muddling around with.

Ugh - I spent some time writing a 1802 simulator
and wanted to get Tiny Basic going on it. I just went
That was poor planning. ;)
though my manuals and I have the Basic manual, but
have
seemed to lost the hex dump for the Basic Interpreter itself.
Well if someone else doesn't drop a box of stuff on you I have
Quest TB for the 1802 somewhere safe. I can zap a copy of
the dump. But you can't have the paper tape!

Good runs under W95/nt then, have that running.
M!... Ah UT4. have manual.
Wheres Bin/CPP for it?
Last emulator for 1802 I'd played with was z80 based, even on a 4mhz z80
it was faster than 1802. I wonder where I put that.

I'm working a version of it and hope to have Linux
ported to my elf tonight. It's that dang 1802 memory
management that is holding me up ;^)

Was this for CP/M? I'd love to see a copy of this.

Memory management? It's a flat 64kb space.

It was z80 binary that ran on most anything as it carried it's own IO
but I got it as a binary, it was on one of the sites out there many
millions of years ago. There was also an article in Byte (or maybe KB)
back then for an 8080 emulator for 1802.
What made the 8080 one interesting was X,P,T, D, DF and register stack
were displayed like in the RCA manuals in emulated time. So the need for
IO was no there.
