Those calcs seem very limited. They probably have only th ebare minimum to support mathprint.
I dont think it is possible to program on this calc. Reason 1: No [prgm] keyReason 2: No [alpha] keyReason 3: No catalogReason 4: MathPrint ()

They probably have only th ebare minimum to support mathprint.With 128Kb of ROM (like the TI-82 or TI-85), with a 4-bits CPU (like the HP-48), and with a dot-matrix LCD like all graphic calculators, I don't think those calcs are limited.They have a very interesting hardware.The CPU has 64 registers.You've got 4Kb of DataRAM, 1Kb of WorkRAM and 2Kb of DisplayRAM.The RAM might be small, but just think to what has been achieved with the TI-81...

The TI-80 is not fully dumped yet (let's say 97%), but the missing bytes are very hard to get.Anyway, it is using a 16-bits proprietary cpu from Toshiba (T6M53A).

How did you get another 30%?
