Atari 520STM TOS 1.4 and 4MB ram upgrade.
Posted: 21 Nov 2023 02:22
Hi guys,
Looking to get some direction before I place an order in Exxos's store. I would like to upgrade my A520STM with the following:
SQUARE PIN CONNECTOR STRIP - 2 pieces [0158]
ST/F/M 6 CHIP TOS 1.04 USA [0124]
STM 4MB RAM UPGRADE [0240]
I am using a local installer to do this for me, as it's beyond my soldering skills.
Does the above look right to have all components needed to upgrade TOS to 1.4 and ram to 4MB?
TOS 1.4 should be a drop-in replacement, right? Or does this require additional modification in order to work?
Attached is a picture of my actual motherboard.
