I have just learned of the sad and premature passing of Archer Maclean, who was one of the 80s generation of individual UK games programmers who became household names. Archer was responsible for Dropzone on the Atari 800 and for International Karate on the C64, among other things. There is a...

Probably a question for Daver2, whose fine work this test firmware is. I'm involved in a PET thread on another forum, the owner has a Tynemouth Software ROM / RAM gizmo sourced from TFW8B. It looks like the Gizmo has some version of Pettester available as an option but its behaviour on the...

Sorry if this is not the right place but I don't see any specific sub-forum for questions about the website itself. In a recent post I attached three photos, two taken in landscape mode and one taken in portrait mode. When viewed on the camera itself (A Canon IXUS series compact) and on a...

I'm surprised nobody seems to have mentioned this reboot of the C64 in mini form, see here: https://thec64.com/ I never had a 64, here in the UK you were usually in either the Commodore or Sinclair camp, or possibly had an Amstrad CPC unless your parents had a bit of money and then you might...

The subject of rainbow coloured ribbon cable or 'Spectra-Strip' came up in another thread in this forum. One of the reasons I prefer it over grey cable is the fact that the colours used in rainbow cable correspond to the colours used in the resistor colour code, so the first wire is black=0...

I've tried, but I can't seem to find a list of the file formats and permitted parameters for each file format for attachments to forum messages. I'm asking this because I've just tried to attach a .WAV file (ZX81 program file audio) to a post and the entry for the selected file was EXed out as...
