I have a 2.0V TI-81 that I'd like to dump the ROM from. How do I dump it? I have Unity loaded.
I also plan on getting some other ROM versions of TI-81s soon (maybe some undumped versions [in my fantasy world of boundless budgets
]), and I'd like to dump those too; I'd prefer a dumping method that works across ROM versions.
FloppusMaximus used an OCR approach in this thread:

The tools he posted appear to be lost. I have a copy, if someone can point me to a place I can upload it. Warning: it's no picnic.
Hi - ROM V2.0V has allready been dumped.
Are you looking for a copy or do you just want to try it yourself?
As we don't have a link port, the method uses video + OCR.
It's available here:
http://tiplanet.org/modules/archives/downloads/dump81.pdf
Dumped versions are:
- 1.1K
- 1.5K
- 1.6K
- 1.8K
- V2.0V
V2.00 dumping is in progress.
Undumped known versions are:
- 1.0
- 1.1
- 1.6V
It would be great if you could help us
