Does anyone on this ns know if the ROM in the TI-85/86 is a seperate
part or integrated into the processor? The trend nowadays is to put as
much as possible onto one IC.
I agree it would be nice but.....
The usual reasons against a replacable ROM are, (1) extra cost and
(2) reduced reliability. I know the extra cost is small but in designing
a product you have many such trade-offs that can add up to a significant
cost. As regards reliability, every extra connection adds to the fail
rate and sockets are worse than solder.

been there, done that, understand their design decisions.
