RE: Portable Plus - Additional RAM
Hi Dave,
until now I only made a copy of the BASIC ROM. I guess I would have to learn something about the correct ROM format, just burning an .exe - file won't be enough, correct?
Or is that easy?
And I would be restricted to 128 kB per EPROM-pair when using 512kBit EPROMs; I know there have been special 1Mbit Eproms in 28 pin housings according to an ad in the Portable Paper, but of course I have never seen such a thing.
But of course this solution is much better than nothing.

What is your favorite ROM configuration for the PP?
