The remaining stock of QL-VGA was sold in under 24 hours on SellMyRetro (wow) and I’m asked quite often for more. The thing is, all cables for QL-VGA were hand-made and making cables isn’t exactly my favorite way to spend my day. I inquired some cable companies for professionally made cables and the prices are… Read More »
I introduced a bug in QD version B.05 that when the window was configured too high to fit on the screen (either by configuration or by command line parameter) QD will corrupt the memory. Curiously the feature of per-extension highlight handling was the culprit, a very unexpected side effect, so thanks a lot to Per… Read More »
A heap of dung I’ve been working hard behind the scenes to release a new version of the QL-SD ROM driver. The starting point was that Urs König asked me about a mysterious heap corruption with QL-SD when using his QL/E distribution under Minerva. And mysterious it was, after stripping down QL/E’s monster boot file… Read More »
This weekend the German ZX meeting was supposed to happen, but for some pandemic reason it didn’t. Which is very unfortunate because not only did I produce a batch of QL-VGAs for it, I also had a secret product in development that I wanted to reveal there: QL-SD ROM. Please note that everything I write… Read More »

I’m not an electronics guy by trade, so this is some tough order for me. The first PCB I ordered looked gorgeous, but it was already obsolete… Read More »
The QL and its non-standard video interface has always been a problem, even more so since the introduction of LCD monitors. Since I got my QL out of storage a few years ago I’ve been looking for a solution. I bought all kinds of Chinese video converters, the GBS8220 for example produced a very unstable… Read More »
Prompted by a customer request I have extended my QL-SD demo file with a few free QL games, 20 in total, including some that were never available for free before but for which I have the rights to release (basically the Jochen Merz catalog, thanks Jochen!). I went to great length to try to make… Read More »
I have released the QJump versions of QMON here.
I’ve released a new version of Minerva, get it here.
The last few days I’ve spent way too much time analyzing the (Super)GoldCard boot ROM. The sources supplied along with SMSQ/E are only sparsely commented disassembly that was basically impossible to read. It irked me to no end that I didn’t understand the code and finally I did something about it. The process had a… Read More »
