What kind of processor is used in the TI-85. It is not a Zilog Z80,
since it is made by Toshiba. But it is at least compatible to a
certain degree to the Z80. Does the TI-85 processor support the full
instruction set of the Z80? Does it support any instructions that aren't
in the Z80 instruction set?
Also what is the word size of this processor? 8-bit?
>From what I can recall the Z80 had memory refresh
circuitry built into it, now it would be silly for TI to put dynamic
ram in a calculator. So is it implemented on this processor? Is
there an R register? Is it safe to use it for other uses?
