My mini TV has arrived and with a bit of fine-tuning we're in business:
However, the quality is pretty poor. I can only get a clear display if I stand up to the right of the machine and hold onto the UHF cable, which it makes it pretty hard to key stuff in 8-( The Sony TV remote makes a great monitor riser though.
Better news on the saving/loading front though. You can see
what looks like an uncased RAM pack on the rear of the ZX81. I really couldn't face the prospect of using a retro tape recorder so managed to source a ZXpand unit. This is a great piece of kit, containing a 32K RAM expansion and an SD card reader. With a 512Mb card in there I probably couldn't ever find (let alone write) enough code to fill it.
I was concerned at first that it wasn't going to work but it turned out that the expansion connector contacts were corroded and needed a gentle clean up before it would boot up.
Saving my test code took about a second and loading a simple game took about the same so this is going to make life much easier.
Better think of something to code now...
