As a quick aside does anyone know of any games that rely on this behaviour to work? It would be interesting to prove it actually does something.
I tested the +3 with a DIVMMCFuture and it worked fine. Once I got it working, anyway. My DIVMMC is VERY picky on +3s. I have tried it on three of them and all are the same - there is a sweet spot where it works and many where it is ignored.
I tried my Retroleum Smart card (which normally works fine although it only loads 48K games) and it didn’t work. I desoldered the resistor and it worked again.
Has anyone tried this and found any hardware no longer works?
Moving forward I was thinking about either -
A) Not bothering with it - I have plenty of Spectrums to load stuff that won’t work on this. Although I do quite like the +3 for some reason. The video quality is superb from it.
B) Extending one side of the wire to a switch and therefore be able to switch the mod on or off. I assume to do this safely the Spectrum would have to be switched off?
Any thoughts appreciated!
