SIMTEL (was Re: Source code for 805x line-by-line assembler?)

I found a number of hits there from GOOGLE, but found, also, that they were
apparently out of date and inaccessible.

A traditional macro-assembler is a wonderful tool, but probably inappropriate
for inclusion in a debug monitor intended to reside in the processor's
on-board ROM.

I'm wanting to stuff a debugger with line-by-line assembly/disassembly
capability comparable to MSDOS' DEBUG or, at least, CP/M's DDT, to coreside
with a relatively powerful debugger in the on-board FLASH in an 89C420. This
part can run the debugger from its internal ROM, yet, by means of a little SFR
trickery, run application code in a full 64K code space map in external
memory, together with a full (almost) 64K external data RAM map as well. I
find that notion appealing. That way I don't have to make last-minute tweaks
tethered to a PC, but, rather, can operate in native mode.
