Likely the sense amps can be replaced by some species of modern op-amp that can run off 5V.
A good start. What exactly is stored in core, which was later eprom?
Umm, some generators deliberately didn't have a circle. But the circle generation should be straight forward to fix if it is meant to have one.
PAL encoder separate box on all the earlier generators?
Amazing really that we bought a ZX Spectrum and I did a basic test card in BASIC for the screens we were aligning in 1982. It was never used for anything else. I left that company I'd founded in Jan 83.
Edit:
As this one was ex-BBC it probably does have a circle.
