Mainly for my own amusement, here is a list of some of the computer equipment I have owned over the years.
All these have now been donated to the Retro Computer Museum, where I hope they will continue to give enjoyment.
My first computer! If you can call it that. Hex keypad input, 9 seven segment led output display. Didn't do anything when switched on until you entered a program, one byte at a time. I was used to the idea of machine level instructions from my day job, but not being able to run a program or even load one from a cassette tape (3 characters per second max.) until you'd entered a loader program, was just too much like hard work. This soon got relegated to the loft.
Wikipedia has some information and links to enthusiasts.

This is a model 2001-8 from 1977, with a small scientific keyboard and built-in cassette player for program loading. A real improvement, but still slow. Diskette drives were available, but too expensive for me. Later versions had full sized keyboards for business users.
The best program on this machine was "Space Invaders", an almost identical game to that available in pubs at the time.

Acquired for a work project, but soon kept for home computing. One of the best machines there have been. Despite using the same 6502 processor chip as the PET, the addition of specialized I/O chips removed pressure from the processor, and it flew by comparison.
