I bid £200... and have just been outbid by someone who's bought over 900 items. Though the person who's bought 4500 has been left behind...

I'm guessing the high number people are probably those who buy and try to resell at a profit.

Sometimes the old lubricant just gets too sticky and the platter gets stuck. Sometimes it's the coating itself. Sometimes I can only read them when th...

The starting assembly programming thread inspired me last night to try to extract my code for the terminal emulator I wrote in 1988/89 from the development floppy. First I had to get an image and I managed to do this via macOS using 'dd' in a terminal. That was the easy bit. Finding a useful emulato...

A long time ago, in a galaxy far, far away... I started programming on the QL using the Computer One assembler/editor/monitor suite plus the "QL Advanced User Guide" from Adder Publishing. They were both fine for the job. I know that the C1 stuff has been preserved but I don't know where y...

they hit F2 for the TV.

I've just tested one of the metal box with white lettering units from eBay and it loses 4 characters from the right-side of the screen.
