[TI-H] Re: building a TI92plus module
Yep. That's the file I meant!
I also agree if u say to have a circuit diagram of the plus module :-)
Should be possible to emulate that "orbit" chip anyway.
Why not putting a SRAM/FLASH/uPC on the plus+ module
and control the _WE pin of the flash with the uPC?
So the calc will think it's an original one.
Maybe also a PAL is enough to do so but I'm not so familar.
If it helps i could desolder the Flash and read it completely
with an external programmer device...
The instruciuton code in that module is it MC68k code or other?
not so difficult to reassemble the first 64k and maybe also patching it
so the TI boots up without the orbit chip :-)
