Re: Q68 direct sector access

I dont see why Id want to do that considering the routine I just posted (above) which does exactly that. It is safe and just does the job. For users who may not know where to poke, it requires no specialist knowledge. I wasn't aware that you want a smooth solution for others, not just rename one or...

Compared to previous converters, it is still very cost effective.

Re: ntsc sinclar ql schematics ??

A little off topic, but what was the US QL keyboard layout? Was it close to UK?

Re: Qzero performance update

Hi Derek, Can Ethernet be added to QLbase, as QLbase, is an excellent addition to the Qzero. Theoretically yes, but it would be a very different board layout. Also, it would consume signals on the 40 pin GPIO header, which I want to keep as I/O for the moment. I may try and design a custom enclosure...

I'm all for QL side programming, but if all you want is to change is the volume name of a few images, why not use the hex editor on a PC?

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.

Qzero performance update

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?

Re: Q68 direct sector access

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...

Re: PiStorm

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...
