Now loading. Time for a cuppa while that finishes...So for the big test. Pressing keys on the keyboard let me move around the menu so that was working. I was able to browse the SD card so I knew that the card slot was OK. I’d got a tape image of Jet Set Willy 2+ (I think a separate article will be needed for that) and I could hear the tape loading so the audio circuit was functioning too. And several minutes later I had a game!
But don’t take my word for it: check out the video below. I’ll try and do a better recording when I have a better setup (and cars aren’t driving by outside).
