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.

Don't pay any attention to the L&H numbers, there are other numbers on the chip, that read in ascending order. There are equivalent numbers on the roms that are already on the 1.0 roms. You need to put the new eproms in the same ascending order. I can't remember the exact pattern that resulted of the L&H numbers, but was one of the following on my 1040st. H2 H1 H0 L2 L1 L0 or H0 H1 H2 L0 L1 L2 Bill Powers ---- Digital Equipment Corp. - Advanced Service Delivery Systems - Stow MA The opinions expressed above are my own, not my employers, so there.

I looked at the top line of numbers in my 1.0 ROMS C026160-001 C026161-001 C026162-001 C026163-001 C026164-001 C026165-001 then (ignoring the H0, L0, etc.) looked at the similarly sequenced (???0 thru ???5) numbers on the 1.4's and dropped 'em one for one.
