[Coco] Re: Nitros9 and the 86 GIME again

Charlie,

The machine does have a version on SIMM memory in it. Didn't boot. I don't
run '86 GIMEs in any of my machines. I thought I had more of them but only
had two of them that I could find. For good reasons, some of them we know.
Tandy released a newer version of this chip. Knowing Tandy and how little
they liked to spend money, it must have REALLY been a NEEDED reason.
