My first contact with computing was a contemporary of the ZX80, the Grundy Newbrain (https://en.m.wikipedia.org/wiki/Grundy_NewBrain), which my father used to repair. Primarily targetting the business market, it was a pretty powerful 'computer in a keyboard' like the Sinclairs, running a Zilog Z80 with 32KB(!) RAM in the base model, that could be expanded by adding another 64KB, which came in a box about the same size as the computer, and attached via a ribbon cable in the back. Another similar unit housed a disc controller and CP/M ROM, and daisy-chained off the other units using the same ribbon cable bus, allowing up to two 5.25" floppy drives to be attached. I had these three units stacked one on top of the other and it was like programming a shoe box.
A notable feature of one model was a 16-character vacuum fluorescent display built into the main unit, so you could in theory use it entirely without a separate screen, but more practically it was separately addressable and therefore presumably intended for displaying ancillary information.
Being a kid at the time I was very interested in gaming and I was lucky to have had quite a few including a great PacMan clone; one of the best was Peat: https://youtu.be/oGGjVMNTJlQ - water the plants, deal with the pests, harvest the carrots... fun times :-)
