I'm trying to put a list of parts together for the startup area. I've found most of them but I'm missing UM5 - looks like an Apple specific clock IC Y4 - presumably a crystal for the clock F3 - a fuse? Is there a complete parts list anywhere or does anyone know what these part are? I guess...

What an amazing piece of work that is!

I've been cutting my teeth on an Acorn RiscPC. So far I've had to fix the traces and replace components in the battery area, including the CMOS chip, several other ICs around the board. Still tracking down the problem of no mouse buttons...

Well I've pulled it apart and it ain't pretty. The PRAM battery has completely destroyed the battery holder contacts. It looks like it was stored on its side, which is probably good because its done the least amount of damage (but bad enough) - imagine the damage to the simms if it had been the...

No power leads but hopefully they are standard kettle leads not some Apple special. Just noticed the broken 9 key are they easy to get? No mouse either so I'll have to source one and a SCSI SD device for the hard drive.

Well here it is in all its glory. Its been in a loft for many years but how it got this dirty I'll never know. Looks more like Cinderella Design (before the fairy godmother) than Snow White! I don't know how to identify the graphics card, there doesn't seem to be any silk screen id. It looks...

Ah, sorry, I see. If the monitor isn't working I may yet need the adapter.

I have an upgraded model A (from new) with recapped PSU after it took up smoking; a Master from ebay with upgrades for SD hard drive and RPi second processor; a RiscPC running RiscOS 4 and Win95, and a basket case RiscPC that I'm trying to revive. Indeed you do. I'm in Somerset. I haven't...

I've been tinkering with computers for years, mostly Acorn machines for fun but I've never owned or even used an Apple. While trawling ebay for more Acorns I stumbled across a IIcx and monitor for sale at a very low start price and no bids with only a few hours to go. I thought I'd put in a...
