- The SpecDrum software is not a game. This is a list for games only;
- There are incompatibilities between the +3/+2A and some older peripherals due to a slightly different design of the multi-purpose edge connector - some of the signals are not placed where they were on the previous models. This might be the case.
I've got the SpecDrum hardware and +2 and keen to maybe see if I can debug this/get it working. Do you have any more info on the signal issue? Anywhere I can look/read?
Seems like tis a rabbit hole I fancy going down to get this working on the +2 so any help appreciated. Thanks

It uses the unregulated 9 volt line, which isn't present on the +2A/+3. +9v was connected to upper pin 4 on the 48/128/+2 edge connector.
Appreciate you moving the thread, apologies. Thank you for the schematic, this helps.
So if i've understood this right, the +2 does have the 9v on lower pin 4 of the expansion slot, so that would power the TL084 right?
What seems to be happening is that it does load but zero input from the keyboard is possible, which gives the illusion that is has crashed.
I think maybe it's better to start a new thread as this could more firmware than hardware. cheers
