I was wondering if you could build a handheld computer with both a Z80 and a M68K so it could play both 83/84 and 89 calc games.
Could you do this? And if so, how?

Yes, you could.  No one sane would make it though -- it would have a *very* limited market and the prototyping costs/development would be hell.

I wouldn't want to sell it...
I just thought it would be a really fun project. How could I do it? How could I connect the processors to the screen and keyboard and stuff? Could it have a TI Basic interpreter? To what extent could I pursue this?

It would be... interesting to try sharing the hardware between the processors (for example, what resolution would the LCD have?) I think it would be much easier to make a generic handheld computer and write TI emulators for it Tongue

You could do it by buying the nessicary parts and clicking/soldering them together.  And you could make a BASIC parser.  Why all the work though?  It will cost you *a lot* and will be more work than necessarily needed.

It would by definition have a TI-Basic interpreter if it's running TI operating systems (which is pretty much required for playing games)

It would be cheaper to wait for chronomex to finish z680k, his z80 emulator that runs on the 68k calcs. Wink

I suppose it wouldn't be impossible, but I don't know that I'd consider it a "fun" project. It would definitely be simpler (and quicker) to just buy an 89 (or a V200, but sadly they are more expensive).

You could build it with a processor that was backwards comptaible with the z80 or m68k that the calcs use. Then just write an emulate for the other processor. I'm not sure how easy it would be for one to emulate the other though.

Would you want to have some sort of a game-pad in stead of the whole keyboard then? Either way, you'd better start with an 89 or 200 as base and just emulate 84 and 83 on'm.

If you want to make an actual "pure gaming" device, however, with and actual gamepad and all, you'd have to make sure that you can find enough games or edit games to work with only a d-pad, and a few additional buttons. That's the sad thing about TI-games, most games have somewhat similar controls (arrows + 2nd and Alpha), but not all of them do.

I have been thinking of such thing as well, basically a calc with just the buttons that are actually needed for games. For a case you could look into 3D printing services, furthermore I couldn't help with this.

There is!

Edit: I could as well just contribute to this discussion. It's cheaper to make a calculator in an FPGA.
