Re: My QL failed

That looks like minerva is running and has tried to print a ram error. And you are generating a valid video signal, my money would be on a failed address or data line somewhere around the ram (bad chip, multiplexer chip fail etc)

Re: sQLux Foibles

Interesting question is on a BBQL are the pixels always square? (also this goes for the clones). No they are not. In 512x256 QL MODE 4, I double horizontally and triple vertically for VESA standard 1024x768 on 4:3 monitor. That roughly provides the QL aspect ratio seen on CRT historically. Thanks, ...

Re: Today I Received...

For the Pi0 sQLux (based on uqlx) can run fullscreen on the console (without X11) and is pretty fast.

Unfortunately the lack of proper GL support under X11 makes it quite slow in that mode, but still can do fullscreen!

[note: I am biased as I wrote the code to do that]

Re: Writing Gotek QL Image Disks

I downloaded the latest, and was compiling for osx. I think I mailed you about it. https://github.com/SinclairQL/qltools or https://github.com/NormanDunbar/qltools are where you should be getting the source from. The current version is 2.15.6 and writes dd/hd/ed images at full size as opposed to 2....

Freenode and Libera.chat are at war with each other, and they seem to be not caring which IRC servers they wage war on :-(
