For fun I have knocked up an interface to connect a 2732 EPROM to my Apple-1. It all works fine, can see what I have programmed into it on the monitor and have loaded the A1 assembler into rom and that runs perfectly :)
Now, apple basic sits at E000 which would be easy to change the select line for that bank of ram to make the eprom sit there instead.
I suppose I have a couple of questions, does anyone have a binary or Intel Hex copy of Apple basic and would it work ? (I have no idea if it just uses the 4K ram from E000 to store the program or if it uses it for data at all)
