Re: Memory tests

If it was just the ramfactor, slots would be high on my list but
there's also the AE GS-RAM that failed the test in the mem slot. Still
I did try it with the IIgs set to both fast and slow and two different
slots.
The IIgs is as bare as you can get. The only card in it is the one
being tested with a single floppy drive connected. It's a recent
acquisition, a IIe with the IIgs ugrade and the ROM 01 update.
