1401 Software

• Dick Weaver gave me a tape with 15 programs on it. These include an "object" deck for Autocoder distribution, several 1401 utilities, and a 1401 simulator written in AL for the System\360.
• I have found Autocoder, and written an Autocoder of my own.
• Paul Pierce (http://www.piercefuller.com) found Two-tape Autocoder. I haven't figured out how to make this run. It's easy to extract the "cards" from the "listing" -- they all begin with &. Then you might need to do some translation to get the special characters into the range that your favorite simulator uses. When you run it, phase 1 will load itself onto tape 1 and load phase 2 (using R 40). Phase 2 will load itself onto tape 1, and load again (using R 40). Phase 2 ends with EX SYSTEM and then END SYSTEM, so phase 2 loads itself onto tape 1 again, and then again uses R 40. But now the read area has been clobbered (by the /167080 generated by END SYSTEM). Please contact me if you remember (or figure out) how to make it work.
• Autocoder generated different boot loaders for different size machines. Here are a few more that I invented.
• Jack Bresenham sent me code to drive a CalComp plotter attached via an RPQ to a 1407 console typewriter. It shows the four directional commands. I don't know what the "pen up" and "pen down" commands were. Do you?
• IBM provided a core dump routine. Here's a modified one from the IBM 1401 General Program Library. I've added some annotations, disassembled it, re-assembled the disassembly, etc. The file dump.txt is a transcription of the document 1.4.124 from the 1401 General Program Library. Everything else was derived from that.
• Paul Pierce found the diagnostics tape. He also has a scanned-in copy of the diagnostics manual.
• Paul Pierce has Fortran v3m0 and Fortran v3m4.
• I've disassembled some of the decks that CHM got from Arnold, and reverse engineered and re-written some of those. These are (for now) all mixed together in one directory. The files beginning "d1401tp" are the diagnostic tape from Pierce; the others are mine. Each diagnostic is in a separate directory beginning with a digit. I haven't done much with the ones that have letters in their identifiers. They're not in the manual that Arnold sent to CHM, and their code is sometimes inscrutable. Programs in new-* are new diagnostic regimes I have written. The Fortran directory contains a deck disassembler, written in Fortran 95. The g95 compiler can compile it.
• Ralph Reinke gave Paul Pierce a dump routine from Germany.
• Ralph Reinke gave Paul Pierce Two versions of SPS. I haven't made a nice web for this. All that's here are a gnuzip-compressed tar file and a .zip file.
• Dick Weaver gave me a Tape-to-printer one-card program.

Please contact me if you have any more IBM 1401 software.

I'm still interested to find Cobol, Sort 6, Sort 7, RPG, Fargo, any of the utilities, any of the comtributed programs, ....
