My first "PC" was a Sinclair ZX80. I got my soldering iron out.

Much later on (1986ish) my Dad bought a Commodore 64, unfortunately he plugged the power lead into the video socket, when me and my brother arrived home for Chrimbo. Dad got it repaired and it served us very well for several years.

I still have that C64 and it was repaired again a few years ago (re-capped). It now has a USB interface etc. I also have an original Quickshot II joystick and it still works fine.

My first "real" PC was a 80286 based thing. A maths co pro (80287) was a Chrimbo prezzie too and costed something like £110. It had a whole 1MB RAM and the co processor enabled me to run a dodgy copy of AutoCAD. Yes, AutoCAD used to run in 1MB of RAM! The next version needed something mad like 32MB minimum.

I have a modern mouse and mechanical keyboard, but I tried to make everything as beige as possible...
