It's also quite likely you popped the new roms by reversing the polarity. Might have broken one or two over the years by doing this 8-)

Rom wise, if it was me, I'd use USA roms with USA machines and keyboards, only for 100% compatibility with the machine and keyboard.

If nothing else, UK STFMs are still reasonably cheap at the moment.
I'm gonna leave the PSU unless it breaks. This Atari had never been used so everything is in amazing condition (even the box was new!)

I'll take your advice and order the US ROMS for 100% compatability.

What's your next issue?
If it ain't broke, test it to Destruction.

Happy to report that I've now successfully upgraded to TOS 1.04. Notator now loads 35 sec. faster (with no pauses that feel like crashes) and I can now copy and run the program disk without getting an error. Very relieved. Thank you all for your help! :)
