I am using a Currys 'Medion Microstar' tower desk pc with an AMD 'Athlon 2000' processor, from 2001. Upgraded the memory from 256Mbytes to 1GB; original DVDRom knackered up and was replaced with an LG RW dvd drive. Original Samsung CRT monitor was just too clumsy - now got a Philips LCD screen.
Until 18 months ago, I had a BBC 'Model B' from 1983. It was an 'issue 7' motherboard, 6502 processor, 32kb of ram, audio cassette drive, 5¼" floppy disk drives, 9 pin dot-matrix (Brother clone) printer, 24 pin dot-matrix Epson printer, Philips colour monitor, teletext adapter, video capture add-on, speech synthesis, and internal sideways ROM board. Because it was taking up space and as I was due to move house, it got the big heave-ho.
