ZX80 in 1980 modified so it had white txt on black screen rather than the black on white.
Commodore 64 with disk drive
then BBC B and the cassette tape was faster than the disk drive on the commodore 64.
At college I was working with a mixture of AIM 65s and a Cromenco System 3 with 8" floppy disks and at night school it was BBC Micros in a network.
Then the Commodore Amiga 500
at that point I built my first PC a 286 with a 50MB HDD
Then a 386SX with a 387 co-processor and that takes me up to about 1992
I went AMD for a while with the first Athlon 64 in 2003 and I have used a 64 bit operating system ever since
Now I am using an Intel i7 965 which was the highest spec CPU I could get 10 years ago, it has been showing it's age for a while especially with it's 24GB memory limit and the motherboard's lack of support for dual GPU cards but it still runs most of what I throw at it, the motherboard can be flaky and the power button circuit no longer works so I have to use the power button that is built into the MB
