Yes, I know that for quite some time. This guy contacted me (more than 2 years ago, IIRC) but he hasn't been interested in sharing/selling the ROM, so I didn't really understand the exact purpose of his mail. Since 2008 I am into other things anyway, and don't have time to bother with TI-59 ROM dumping & emulation ...

Apparently TI doesn't allow him to publish the ROM listing, a bit on the very wacky side, as the listing is, due to the expiry of the patent, in the public domain anyway.

It would be possible (probably) to extract it from his emulator if you trace the microcode and strip out all the non-interesting parts, but the trace & debug files very quickly balloon up to triple-digit megabyte sizes...

For what it's worth, do you still have a version of your TI-95 emulator that relies completely on external files for the ROM contents? Stephen Reid (one of the principal architects of that machine) has recently joined the TI-59 mailing list and sells the RPD-95 in Apple's App Store (in tiny quantities, around 50 so far). I would like to see if I can update some of the ROM code with my own code, but your latest versions have everything built-in, which makes this if not impossible, then at least very hard.
