I picked up TOS 4.1 today -- had to drive to Phoenix (I live in Tucson
and we have no ATARI dealer) to get it.
I was wondering if anyone can help me with the correct placement of
the TOS 1.4 chips?
I tried two different iterations:
A. L0
L1
L2
H0
H1
H2
B. L0
H0
L1
H1
L2
H2
These configurations are in a 520 ST that's been upgraded to 1M via
piggyback.
My TOS 1.0 was in the following configuration:
--------0
--------1
--------2
--------3
--------4
--------5
Can't remember the numbers in front, but you get the idea.
In either configuration the screen (mono) stays dark and nothing
happens. Was just going to try a few more configs but thought I
would ask first and save the wear and tear on the pins ;-).
Thanks for the help.
