https://peertube.v1.root42.de/videos/watch/651b50cd-7e12-4d5a-a56b-eecc5470ed17 I have acquired a Sinclair ZX81 from 1981. It is a Z80 based machine with e measly 1KiB of RAM, and arguably the worst keyboard ever. It has only RF video out, so you need a very old TV for that. We will do a composite A/V mod to have more and better options of video output, and it will require a new membrane keyboard, as those usually fail after all these decades.
