I supposed I should make my mark in the official manner...
Hi, I'm Richard, I'm down in Portsmouth and there are far too many keyboards in my house.
I have an Acorn Econet of 4 machines (2 Model Bs, 1 Master 128 and an A3020 Fileserver). The Clock Box, terminators, cables and T-pieces are all home-made

The Master 128 has a 3Mhz 65C02 Turbo Co-Processor fitted, as well as a 180Mb IDE Hard drive and Music 500 Synthesizer.
I also have a home-made ZX Spectrum 48K, an Acorn Electron, an A4000 Archimedes, an A3000 (with no PSU), Risc PC 700, Commodore Amiga A500+ (standard issue), Sega Master System, Sega Megadrive, Super Nintendo, Game Boy.
My more peculiar systems include two SGI Indys with 200 and 250Mhz MIPS R4600 CPUs, A 64-bit MIPSEL 1U Rackmount Cobalt RaQ 2, Sun SparcStation 2, Sun SparcStation IPX, 2 Mac LC475s, a Mac Performa 6330.
My "regular" systems are a G4 Mac tower, two PCs (one Win XP, One Ubuntu Linux), and a P166 DOS Box.
I have a fascination with old systems and the electronics thereof. I have plans to build a 128K ZX Spectrum laptop from scratch, an Acorn Atom (eventually) and an ethernet interface for the BBC Micro.
I can offer to repair ill systems as long as people are willing to pay postage and wait until I have some spare time. My specialties are Acorn systems and ZX 80/81/Spectrums.
I'll also bringing *stuff* to the open day on May 31st

Cheers
-- Richard
