I thought only the TI-58/59 could print mnemonics for keycodes on the PC-100A printer when listing a program.

I have an SR-52 Aviation library manual (1976) that is in a larger format and three hole punched (as opposed to the earlier smaller spiral bound ones) that has program listings that are copies of printer output (dot matrix as opposed to typeset) that show mnemonics.

Was this a later feature of the SR-52/PC-100A? Or maybe some in-house hardware that TI used to make the listings? Perhaps something they developed when working on the upcoming TI-58/59 printer mnemonics?

The PC-100 (no letter) had a switch in the battery storage compartment for SR-52/Other The "Other" being the TI-58/59. I'm not sure about the A. I know the switch was removed from the C version which didn't support the SR-52.

Hi Tom,

The PC-100A Had a 3 position switch (OTHER, SR56, and SR52).
Listing a program from an SR-52 with the switch set appropriately only shows line numbers and keycodes.

I haven't tried the 'other' setting with a 52 in place though. Maybe that's it.

There was a TI-59 program called "SR-52 Program Listing". You can find examples of such SR-52 listings with keycode mnemonics produced by a TI-59/PC-100A in PPX-V1N6 page 5 and PPX-V2N2 page 4. These newletters are available on Datamath.

Amazing! Thanks for the solution.

... but I bet it's damn tedious to key all that into a 59 just to get a listing with mnemonics.
