I was looking into the idea of using on board RAM in an FPGA, but even with the basic QL display resolution, the amount of block ram you need means using quite a large FPGA in relative terms. And if you want higher resolutions, it just ramps up. Thinking about the way the video is produced in the 83...

Anyone know what the great man is doing now?

Happy Birthday Sir Clive - if you have retired i hope you are enjoying it. I have enjoyed several of your products, but my favourites are still the QL and the Z88, although the black watch get's an honourable mention

Given that some fans will just attack each other even if they are not playing, it could be any time. I am going for day 2 (15th June) - just have a feeling...

Happy Birthday Jan - have a good one

This makes more sense now on the switch side of things. The switch enable will trigger that lower of the 3 comparator's (there are 4 in the 339 package), and that in turn will switch Q6 on, allowing the SW pin to rise towards +12V, it would normally be dragged to 0.6V by the bias resistor to -12V a...

Loving the old 'bench ammeter'

all the best with the clean up. Hope you are able to salvage the majority of the material.
