Hi All The Release 3 of the IBM 650 computer simulator is available from the Computer History Simulation Project (SIMH) site: https://github.com/simh/simh
This release comes with FORTANSIT, the first FORTRAN port. According to Bob Bemer (https://www.bobbemer.com/FTRANSIT.HTM) : FORTRAN (704) 1957 June FORTRANSIT (650) 1957 August (just 2 months later) FORTRAN (705) 1958 September As Fortran I for IBM 704 is lost, FORTANSIT becomes the oldest working Fortran compiler available on SimH. In the sw/fortransit directory there are several source programs examples and the necessary scripts to run then. This is a summary of what's new * New Hardware support: o IBM 653 Storage Unit: provides machine opcodes for Floating Point, Immediate Access Storage (IAS), Three Index registers, Cards Punch-read synchronizers 2 and 3. * New Software included: o FORTRANSIT: version II (S), plus run time PACKAGE with standard Fortran functions. o Reorganized sw directory, separating each language in its own folder. Each one Includes a 00_readme.txt file with restoration notes and comments. * New features: o Support for SOAP opcode mnemonics in addition to regular IBM mnemonics o FAST / REALTIME CPU options o PROP pseudo register o CARDDECK ECHOLAST command to display last n read cards that are in the simulated input take hopper Any comments/suggestions are very welcome.
