So I have a Texas Instruments TI-82 graphing calculator I picked up at the 'thrift a few months ago as a spare. I decided to crack it open today to see what was inside. I knew most TI graphing calculators had a z80, but I thought they were tied up in custom silicon. Lo and behold, there was a bog-standard z80 sitting there with its entire bus exposed. This is just begging to be hacked. Would something like

Thanks Alice.

TI-82 has 32KB of memory. If you want to put a new OS on there, it's going to have to be bespoke.

>>2508That's a lot more than most consumer z80 systems.

>>2533Great, but portability requires a lot of expensive abstractions.
