Owen,
I was afraid you might ask:-) Unfortunately, I gave my brother the
instructions along with the computer and he is now in San Fransico. I
still have a copy of "Schematics and Expansion Specifiactions",
June 9, 1986 with a few notes but nothing that could be considered
instructions. There is a reference to Amazing Computing Vol 2 iss1 but
that may be the piggy backed RAM or the Kickstart RAM hack. As I recall I did
use an article for refence;-)
The jist was to modify the input/output of the DAUGCAUS and DAUGEN PALs
used to control the kickstart RAM. I recall there was article with specs
for to program modified PALs(PAL equations).
It is a moderate amout of work for 256K. Especially now:-)
I'll leave a note with my brother to see if he has unpacked, and can
find my instructions. I never thought anyone else would "try it at home".
If he can't find them I can give you info from my notes but… there is
no guarentee 1)It would work 2)The computer would work. RISKY!!!
