ZX81 composite output

Recently I decided to dust off my old ZX81, the very machine that I learned programming on some 30+ years ago. It’s getting kind of difficult to find a TV that works with it, especially as I have the 1st ULA version that didn’t do the sync signals correctly. So I decided to “invest” (it’s… Read More »

QL-SD teaser

The QL-SD driver seems to be finished (note that it currently doesn’t work with the MiST FPGA board, but there are no more known problems with either the original QL hardware or the MiSTer FPGA machine). Now the boring part has begun, which means hours of reading tax related stuff (selling stuff internationally is hard!),… Read More »

QL-SD update

Just a slight update before I go on holiday for a week. The design of the MDV adapter board has been finalized and I already have the PCBs here: The board can be built into four different configurations of which I will probably offer two: Single slot drive using a ready-made daughter board soldered onto… Read More »

Cueshell – The definitive file manager for the QL

24 years ago Albin Hessler released his file manager Cueshell into the world. It was and still is one of the most advanced programs for the Pointer Environment ever written, featuring a Multiple Document Interface (smaller directory windows within the larger application window) and drag&drop file management. Managing large directory trees became incredibly easy and… Read More »

QL-SD news

(Summary at the end if you’re not interested in the details) Some people know that I’ve been working for quite some time on making the QL-SD work with the late Stuart Honeyball’s masterpieces, the GoldCard and the SuperGoldCard. And I seem to have succeeded, but the way to success took a lot more time than… Read More »

Debugging Minerva

Martyn Hill recently discovered a bug in later versions of Minerva, but couldn’t quite pin it down. I thought it might be nice to write up a little tutorial about how I try to tackle these kind of problems. The most important thing of course is being able to reproduce the problem, which was the… Read More »

QMovie v2.00

In my last post I lied that regarding the QMovie player “I’m done here”. OK, to my defense, even I didn’t know that I’m not done yet. So today I present to you QMovie v2.0: The details and downloads are on a dedicated QMovie page.

QMovie SMSQ/E movie player

This has been superseded by QMovie v2 QMovie is a quick&dirty full colour movie player including sound for QPC. I really didn’t have the time to write this, but sometimes an idea latches itself into my head and I can’t let go until I have done something about it. So the target for this was… Read More »

Wrapping stdcall functions in Node FFI

A colleague of mine needed help wrapping some C DLLs for NodeJS. He’s using the Node FFI API for the wrapping, which unfortunately is a little light on documentation. The problem was that by default Node FFI wraps cdecl functions and there is no mention of stdcall anywhere. In fact the consensus on the net… Read More »
