The world's best—probably only—IBM 701 emulator!
New with version 1.06: assembler masked WORD and HWORD constants to 12-bits—fixed to mask to 18-bits;
WORD and HWORD now take constant as octal if it starts with a zero; new examples sqrt.a and sense_switches.a.
The 701, introduced in 1953, was IBM's first commercially-available computer.
Unlike other computer emulators, the 701 emulator has a fully-functional front panel and
a complete set of I/O components (card reader/punch, drums, tapes, and a printer).
All 33 instructions are implemented.
To make programming more convenient than it was in 1953, I've added a couple of things that aren't part
of the 701 itself:
a log that shows the instructions and registers in real-time,
and an assembler that automatically punches a card deck and loads it into the card reader.
(The assembler doesn't run on the 701.)
Full details are in the PDF which I'll be adding to during Summer 2013;
I'll post progress reports on my blog.
You can download the emulator for free (MacOS only for now; Windows on the way) by clicking the button above.
You'll also need the Principles of Operation Type 701 and Associated Equipment.
