These days everyone in the club has one or more PCs. In the early days of the club, computers were few and far between. Hardware was very much more varied, with most equipment being supplied in kit form. Here are some of the machines club members have built and owned.

Acorn Archimedes An advanced machine for its day, though expensive.
Amstrad CPC464 Andy's software house got one of the very first prototypes of this machine, and was the first company other than Amstrad to demonstrate software running on it. The ZX81/Spectrum chess program and other games were ported to the Amstrad for its Hippodrome launch.
BBC A and B,
There were several BBC machines in the club, one of which had the Torch CP/M co-processor box.
Commodore 64 Another machine for which Andy's software house developed games.
Nascom Rod's Nascom was housed in a stylish wooden case. It was going to be fitted with brass candlestick-holders, but I think events overtook it and that never happened.
Osborne Express A very neat portable computer, running CP/M on twin floppy drives, with an 80x25 CRT all housed in a neat plastic case.

This was a substantial improvement on the original Osborne as it had higher capacity floppy disks and a clear, full resolution display. 

Andy still has this machine.

PSI Comp 80
A Z80 based kit design published in Wireless World in the early eighties. The supplied system software was awesomely atrocious, but at least replacing it gave Phil some early programming practice.
Rasberry Pi Most of the machines listed here are from the "early days", but a couple of members have this modern hobbyists equivalent.
Scrumpi Andy's very first computer kit. National SC/MP processor and 256 bytes of SRAM.
Sinclair Mk 14 Simon's first machine.
Sinclair Spectrum Andy still has one of these, including Interface 1, a microdrive and dozens of games tapes.
Triton Andy's second computer kit. Started out life as an 8080 with 2Kb of EPROM and 4Kb of SRAM. Ended up as a Z80 with 48Kb of SRAM and running CP/M on twin 114Kb floppy disks.
UK 101 Bob built this from a kit supplied by Chris 'Spangles' Curry, and it still works. Heavily modified with additional RAM, switchable operating ROMs, 4100 b.p.s. cassette interface, enhanced video and 100 b.p.s. printer interface it made him the man he is today.
VIC 20 Another of Simon's machines.
VME rack An Eltec 68020 VME system, running OS9. This is still sitting under the desk at Andy's office.
ZX81 Andy developed a chess program for this machine, using the Triton, which subsequently was sold by Sinclair.
