"Rajko M."
You mean in Fortran IV times ? ;-)
I learned FORTRAN II just before FORTAN IV was released on an IBM 7044.
Worked with a 4K DEC PDP 8. Had to enter binary for the RIM loader to
load in paper tape. The original Burger King point of sale (Manex) was
developed in the early 1970s. Very tight 100% assembler code with no
external storage. It relied on core memory for persistence if power
went down. The modem did not have any UARTS, we would send a bit, go
into a timing loop for 1200 bps, send the next bit until 8 bits + start
and stop were sent. We even had to program the hammer strikes on the
printer drum.. Those days were fun.
