Re: ROM

The pinouts for all the ROMs are the same, you can find them on page 10 of the Plus/4 Service Manual in the Publications section

And 27128 EPROMs can be used as replacements (one of my Plus/4s has had the Kernal ROM replaced with a 27128)

ROM

Hi there,

Can anyone point me to a source which describes the pinouts of the 3+1 ROM's? (in fact all the ROM's would be cool)

And can you tell me if these are suitable replacements for them?

Cheers.
