Re: Saturn 128k Problems

Steve:

I don't know for _sure_, but I've noticed the very same thing when running
the Saturn 128K test program(s) on my IIe.

I've attributed the failure to my having an accelerator in the test machine,
but it may instead, as you suggest, have been because the program was
designed for and is specific to a ][ or ][+.

I've run the tests with both a genuine Saturn card and also a clone, and
have _never_ passed.

RoboCAD, as you've discovered, still runs fine. Go figure.
