Welcome to Inglevale, California!

Inglevale is where Tom Jennings' select documents live.

Documents I wrote, accidentally or on purpose

Really old software I wrote

1970s. My first computer was a SWTPC (Southwest Technical Products Corporation) (wikipedia). I borrowed an ASR-33 from work then later somehow bought an Ollivetti RE-318 terminal, a lovely thing. Both had paper tape (10 char/sec). I bought an old Pertec? 7-track magtape drive (only) from American Used Computer in Boston or Cambridge MA, built a simple controller and wrote code for a tape file system. It actually worked, in spite of myself.

I could not afford the SWTPC assembler so I wrote macros for the Data General RDOS assembler for the Nova 1200 computer to do it. It punched binary to tape in some format and I wrote a 6800 assembly binary loader to read the tapes. This is that code and macros.

This code survived the ages, when newer code did not, because it was printed out in paper and hand written in a notebook.
