Revision of the board doesn't matter, its the 70789 part which is important.AtariFox wrote: 13 Aug 2019 10:59 Does that work on the D1 revision board? or DI , I cant tell if it's a one or an i
Correct.AtariFox wrote: 13 Aug 2019 10:59 So I'd need the STFM KIT DUAL TOS & UBE BETA (NO ROM) [0131] and a TOS104 / TOS102 ROM ENGLISH [0042] from exxos's store?

If your replacing 2 chip TOS with the dualtos board, then its pretty much plug and play.
Brilliant. I've gone and put the order through. Mentions something about an UBE board, but, i dunno what that is. but thanks youexxos wrote: 13 Aug 2019 22:31If your replacing 2 chip TOS with the dualtos board, then its pretty much plug and play.

It allows you to change the TOS version with the reset switch instead of jumpers.. Though the rest circuit in the ST isn't very stable and needs fixing.. so I would just start out using jumpers initially.AtariFox wrote: 13 Aug 2019 22:44 Mentions something about an UBE board, but, i dunno what that is. but thanks you
Yeah height is a issue because of the pins like you say. Hacking of some kind is pretty much normal with these machines. Though generally I suggest soldering the boards in as the ST sockets are 30 years old and not great these days. There wouldn't be a issue with height then.AtariFox wrote: 15 Aug 2019 21:57 Basically it touches the last strip of pins on the top where it slats down just by the board fold.
A bit of persuasion with the hammer and some needle nose pliers has alleviated it a bit, so it will sit on it without touching the pins.
Without me doing this it would not fit, zero clearance completely and would press really hard against the top of the shielding. It looks a bit jank, but, it fits on now.
