I remember the chicken-and-egg problem when I built a development
system for my cassette-based IMSAI, starting from a simple monitor
in ROM.  Should I first write an editor to edit source code for
an assembler, or should I first write an assembler to assemble
an editor?  I think I wound up toggling in code for a rudimentary
assembler through the front panel switches - patching in place
heavily as I debugged it - and then toggled in code into another
area of memory that would let me type the equivalent source code
for the assembler and write it to tape so I could assemble it with
the assembler that was still sitting in memory.  Then I used that
little cat command surrogate to type in source code for an editor.
It was fun to get them both working.
