RE: TI-74 TI-95 8x32K banked RAM/FLASH cart soon, ROM images needed
I meant to write a longer reply yesterday, but got distracted etc etc.

So a few months back, I was reading through the TI PPC Notes Newsletter and on page 10 of the final issue (V14N5) was a notice from Robert Prins on the status of his utilities cartridge project for the TI-95. I've attached a copy of that page to this post. With the newsletter folding, and the tech world shifting away from programmable pocket calculators, it evidently seemed prudent to call it early and offer the programs and source, since producing a physical cartridge likely didn't seem worthwhile, if possible at all.

Intrigued, I found his email and sent him a message asking if he was still in possession of those resources. And he replied with a "yes"! Unfortunately, he also seemed to get distracted, and I never did end up receiving much, although he did recommend I look up the TMS7000 datasheets from TI, which are at bitsavers: https://bitsavers.org/components/ti/TMS7000/

I'm cripplingly terrified of seeming impolite or burdensome, so I've not yet tried following up again. We're all quirky in our own ways, perhaps? If anyone would like to try to succeed where I failed, you can message me for his email address.

PS: The plot thickens a bit regarding hrastprogrammer's TI-95 emulator and its associated files. The zip file containing the images of the cartridge ROMs has one file named PRINS.car that appears for all the world to be his utility cartridge. Though I'm at a loss what most of the routines are or what their parameters are, etc.

PPS: It probably goes without saying that I'm also really interested in this project. I can't contribute much expertise, but I'd really like to be counted as a prospective purchaser of the final products. Good luck with everything!
