Need two things:
1. To replace AY-3-8912 in my Spectrum Sinclair 128K your solution
2. To make my Sinclair 48 k with more memory
1. I recommend you to use emulator 3 channel version instead of AY-3-8912, just as is, place it on PCB or breadboard and connect to ZX as AY-3-8912 according to pinout.
2. It’ll be better if you describe your model, because connection of memory expander is different on different models. If your model use ULA it is probably difficult to increase memory, because all logics is inside the ULA.
