The world's best—probably only—IBM 701 emulator!
New with version 1.06 (Mac): 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.
New with version 1.10 (Windows): 1.06 changes, plus PL/0 compiler
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.
You can download the emulator for free (MacOS and Windows) by clicking the button above.
You'll also need the Principles of Operation Type 701 and Associated Equipment.
