updating my 1040STFM NTSC

[Pixelplaygaming]

Hello,

I would like to upgrade my 1040 so I can make use of it. Currently I have a ACSI2STM and TOS 1.02 US and alot of programs do not function properly with this old firmware. I would like to keep both the TOS 1.02 & 1.04. they are 2 chips Hi Lo 28pins. I also would like to get 4mb installed too. What are my best options on Exxos shop?

I prefer this for the 4MB upgrade: 4MB upgrade

As for the ROMs it's not so easy to get 2 chip sets, however 6 chip sets are perfectly valid as both were used by Atari.

However if you want to have both 1.02 and 1.04 then I'd suggest a ROM switcher like this: TOS switcher
