Not with the current Q68 board, as it has no separate video RAM. But the Qzero runs Q68 SMSQ/E.
As you will see at the meeting, a Qzero with QLbase offers similar funtionality as the Q68, plus digital video out and matrix keyboard, minus ethernet.

Hi, the Qzero has become much faster in the highest graphics resolution. That is possible because the Qzero FPGA now supports the separate video RAM, which was already present on the board. In 1024x768 @ 65536 colors, the Qzero is now about factor 2.6 faster than before, according to the BogoMIPS an...

That makes the D-Sub hood more expensive than the converter Are you doing it without a carrier PCB?

Im trying to change the internal Qdos name of a QL hard drive. Use a hex editor to change the string at offset 6 in the image file. How does one do direct sector access on a Q68 QLWA virtual disk? It is probably not implemented yet. The best would be to ask Wolfgang on ql-users. Not a hardware issu...

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.
