The Sinclair QL Forum

Remember that it would have to have a custom PCB which adds multiplexing onto an 8 bit bus. As mentioned earlier, I meant a redesigned QL PiStorm board. Which would of course have an 8 bit bus. Not something using the Amiga PCB. But a smaller form factor isn't needed for the initial prototype. That...

Has anyone considered ColdFire? (I know Nasta has..) That the very first chip in the Coldfire line but no actual Coldfire CPU. It is a 68EC40 CPU with multiplexed bus. Nice chip, but not if you want to be much faster than a 68060. Some variants can reportedly be overclocked to 300MHz. You lose a lo...

There are several options which fit, the nicest being a board for the CM4.

PiStorm might have quite a bit more relevance on the Amiga that brings a lot of custom chipware that's so deeply embedded in the system that you will definitely want to preserve so it still stays "an Amiga". The QL, well not so much. I think that is the essential difference. Also the Amig...

Stupid question, but how is an emulated processor on a real QL going to be better than an emulated processor in sQLux or similar? Since the emulated Io is superior to genuine IO in every way, couldn't we just make a QL-fitting carrier board for a CM4 for the QL case? Had a similar thought: Effectiv...

Please keep us updated. But remember PiStorm ist not PiStorm. We need to look at the EMU68 emulation, Musashi is too slow.

Good luck with the display... they seem to use varying panels.
By the way, I noticed the QL-typical white/red transitions looked sharper from VGA signal than from HDMI.

Buffee is some super vapourware, its been going a decade and no-one has seen anything! Thanks for speaking more frankly than me. ;) Apollo core AFAIK does not implement TAS instruction, and I think QL software was apparently fond of that instruction! Thanks for the info. And that's most likely not ...

Thanks. I looked into that years ago. Debugging for QL purposes would require an unknown amout of paid support. Like PiStorm, nobody seems to have tested it with QDOS Classic on Amiga, so it's unknown if it can execute demanding QL code correctly.

If you are fortunate enough to have an old flat screen monitor with a 1024x768 resolution and 4:3 aspect ratio you are OK I bought mine brandnew. Similar to this: https://www.amazon.de/JaiHo-Bildschirm-1024x768-Computer-Videoplayer/dp/B07DC9WX3V [...] or to the Q68 which is nice but very slow at hi...
