I remember a 8080 editor/assembler book with a 4k hex/octal listing.
It was so primitive that instructions longer than 1 byte, had to be
assembled as 2 and 3 byte instructions.
Does anyone
know about this? Is it of interest to anyone? I could
either type it in, or scan the listing for someone else :-) The code
would need patching for console & tape I/O, and I don't have any
documentation on how to do this, or even how to use it, but it can't be
too difficult. Forgive me, it's been almost 30 years!
I used something like
that before I had the luxury of a diskette drive on
the MITS Altair. But I don't recall a 2-pass mode from paper tape, just a
BASIC-type editor that read the source into memory (or created it); each
statement had a line number. Assembly in place--i.e. no intermediate
binary output was the normal mode.
