[comp.sys.m6809] Coco III Memory

umrobbin@ccu.umanitoba.ca (12/19/90)

Hi!

My brother has a stock 128k CocoIII, and wants to upgrade to 512k.
I understand that details of this were once published in Rainbow.

Could someone point me to the issue or to an electronic source of this
information?

Thanks,
Steve (umrobbin@ccu.umanitoba.ca)
