Atari 2600 with 4 games. Though I got so good at pole position , it wasn't what score I could get, but how many times I could loop back to zero.after 3 or 4 loops.. It became a bit pointless. I wanted to write my own games at the time.
Some school mates had other machines. One guy had a spectrum, used to take a couple hours to get a game to load. Liked the machine but tapes were just annoying.
A guy had a C64, great sound for the time, but got annoyed following the manual to create a sprite which was a hot air balloon which was corrupted.
One had a Amiga 500. While graphics and sound were generally good, I just couldnt "get into it".
At school there was mostly old BBC machines which just seemed annoying and slow. I dont think i ever won suburban fox

We had a 286 PC at some point. Used to play micromachines during registration

but never really liked the PC. Plus those RM nimbus machines and the smile menu, a bit of fun, but always seemed limited in what they could do.
During computer classes we used to have to do stuff with turtle / logo or whatever its called. Used to take 5 seconds to do the exercise. So what's a bored kid supposed to do for 2 hours... More effects, more colours, more getting told off not doing the exercises

I found a security hole in the school network which another kid took credit for
In the end I saved like mad for a Atari ST discovery pack, floppy drive, so no tapes. A "good" selection of games and also came with many utils and STOS. STOS is where I started out but often I got annoyed at the lack of capacity of 720k floppies. I used extended formats for a long time.
At some point I got a TUS 1.44 floppy kit, which as a poor school kid wasn't easy to buy. But I was never convinced it worked right. But mostly I got annoyed of having to load the driver from floppy all the time., I needed a better solution...the rest is history as they say.
Some years passed and I saved up for a falcon when I started fulltime work and could actually afford one!
Edit:
Forgot to mention I did have a PC as well

was a 286sx25 IIRC. DOS machine. Built mostly from "junk" from the guys I used to work with. Playing doom for hours each night was great. Hunting for the matrox graphics cards and dealing with IRQ conflicts and the rest
Mostly I wanted to run easypc PCB software as it was what we used during my technical training days. We etched our own boards and printed with a plotter. Later I wanted to get online so a bought a cheap PC from a guy from work with win3.11 on it to get on the internet. It didn't last long, and win95 was put on it not long after. Which lead me into the BSOD years
