There were many others. In particular, I did a lot of work on DX-85M.
True, but the Cross Assembler still would be FORTRAN.
The only hand
coded machine would have been the APPLE I.
There were plenty of assemblers around, some even native. Heck, I wrote
both an 8008 and an 8080 cross-assembler (in FORTRAN, naturally). It's
not rocket science. One friend of mine wrote his assembler as macros
for a mainframe assembler. That, at once, gave him all of the advanced
facilities of the host assembler. Wish I'd thought of that...
Only now I have money to play with small computers
(FPGA 8 bit
design) not in the late 70's. I suspect the high cost of hardware
left little money left for software was true for every one back
then.
Do you have any idea of the software offerings from, say, Intel? They
were considerable.
