April 2011 - A complete re-design of the web site and I also have my old URL www.walkerworks.co.uk back after it has been out in the wilderness for seven years! (another story..)

May 2010 - Added 8 Bit Acorn Webring.
April 2009 - Removed contact email address and replaced it with a Feedback Form.
February 2007 - Having looked at all the changes in content and hosting that
has occurred over the past ten years I feel it is time to do a bit of a tidy up. The
first items are the URL and site name. My attempt at a bit of humour with the URL
seems a bit feeble now so I have corrected the spelling with a new URL www.bygonebytes.co.uk. The old name 'Online
Computer Museum' does not describe the content (probably never has!) so the site
from now on will simply be known as 'Bygonebytes'.
There are a few 'features' that no longer work, the hit counter, web ring and the Guest Book has vanished so these will either be fixed or removed.
I have noted that a lot of the pictures aren't up to todays standard, the site was originally build in the time of low bandwidth (14.4K/28.8K modems) so file sizes had to be kept small. Where possible I'll update.
I have also tweeked a few of the text colours.
Added Electron User cover pictures, Instructions for Pace Independent Floppy DD power supply, Marconi Trackerball, Uvipac EPROM Programmer and WE Solderless Sideways Rom Board, Slogger Price list from 1989 and the Z80 Fuction key strip.
Added the Z80 2nd processor software manuals, Fileplan and Memoplan, also some old adverts for BBC Peripherals.

Amiga 1200/Zoom 14.4K modem entitled 'Mort's Abode'. For some reason the
pages are still active although I cannot get access to update them now.
(About a week after I wrote this (April 2001) they disappeared.)
