My first true compy was a Schneider Joyce. It had Mallard Basic and Wordstar on a floppy iirc, and the printer connected via a very proprietary plug to the main unit which housed both the CPU and the green monochrome monitor (I am talking 1980's here - Schneider the German company later sold out to or merged with Amstrad the British).
Before that, I owned a second-hand Sinclair ZX-81 with a memory extention thingy that added 16 Kb (as in a whopping 16384 bytes) to the on-board 4 Kb RAM (4096 bytes). The display was a small 6" black-and white TV I could lay my hands on (Russian Shiljalis, still have it. Runs on 12 Volt car battery, and also on a 220 Volt adapter. Manual includes detailed circuit diagram, for reasons unbeknownst to me).
And way before that, as a high-school student I used to spend some of my free time in the local Capi-Lux store, where they had an TI-41C on display. Or perhaps it was an 11C. It was the first programmable calculator I have ever interacted with. Stopping there after school, I would input the code from the manual (50 or so lines, with a calculator-style keyboard, nothing qwuerty-like in sight) to play "Moonlander". The objective of the game was to iteratively input fuel burn rates in such a way that at the end of your fuel, your elevation would be zero and your speed as well.
Heck, in 1973 I was the first in my class to own a digital watch! It had a LED display. Go figure.
