What type of +2 ?

are you looking for the 128k +2 that came in the (grey) chassis or the +2A/B that came in the black chassis.

The reason I ask is that they are substantially different.

The former 128k +2 (Grey) has only 32K ROM and a ULA, the latter has a 64K ROM and a hybrid ASIC.

Memory contention model is also different between the two. because of this - without a lot of fussing about the latter wont load early games like JetPac as the ROM is different

Apologies, I forgot to specify! It's the grey model. I'll update the description!. Thanks

What is wrong with your current board? Maybe someone here can help with that?
