My first desktop was a Mesh computer. Bought in about 1994. Cant recall its price but reckon it was about £800.
The GUI was Windows version 1. I removed it to make more space.I had a Spectrum 48k - think it was £129.99. Plus Kevin Toms' Football Manager. Paid for it with my share of my dad's estate, which totaled £450 between three of us.
First desktop was an Amstrad 1512 (?). No hard drive, but I think it had two floppy (5.25") drives. It did have a GUI which seemed a load of nonsense at the time (late eighties?) when you could load everything from DOS. £650 as far as I remember which now seems ridiculous, from a computer shop on Linthorpe Road.
