I gave my '250 away about a decade ago. The tapes tended to die much sooner
than this.

Hopefully there's one already been done out there somewhere ...
Brain rot kept me from remembering how I handled this... I
didn't... well, I have a hardware debugger called DryIce-51
or something like that. You pull your 8051, plug this in,
it has its own 8051, and IIRC it has an assembler built-in.
Handy for debugging interrupt routines, althought it's not
a true ICE, so you can't trace through machine states.
Then again, more brain rot... I had *some* kind of monitor,
because for the DS5000, I found it handier to use it than
to pull the chip and stick in the DryIce.
Found the SIMTEL 8051 stuff, at least what I downloaded.
Wasn't much. But I have a WIC-80 tape labeled to indicate
some more 8051 stuff is on it. The 486 with the Jumbo-250
seems to be dying...
