Vintage computers from times of yore…..

Temporarily Subverting the Apple Display

P738

This label started peeling off the trusty old A305 so I finished the job. Before I clean the sticky off, I decided to put it over the Apple logo. I am so going to get flamed for this….

The yellow tinge to the sticker is sadly permanent. It’s UV damage, and while I know about various methods to fix this, I am not wanting to damage the print. It will be reattached to the proper computer layer today when I’ve located the right adhesive.

Making the Old work with the New

P505

Yesterday, I took my Acorn A305 – a 25 year old computer – to another Paul who has developed a rather cunning way of getting these old machines to display correctly on a modern LCD monitor.

After some soldering (a skill I have not developed) and some detective work with some jumpers (used to various control signals to/from the video circuitry), the machine’s upgrade was completed, and we got a display on an LCD screen. I say “we” – Paul was the one doing most, if not all, of the work here.

The really clever bit is that the modification is software controlled, so no need for manual switching. The software knows what signal to send to the monitor and flips the added hardware as required. So it’s invisible to the user. Clever stuff indeed.
