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...

Re: Qzero performance update
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...

Re: QL Pico VGA
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...
Re: PiStorm
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...
Re: PiStorm
There are several options which fit, the nicest being a board for the CM4.stephen_usher wrote: ↑Tue Apr 16, 2024 12:58 pm The Pi would always be too tall to fit inside the BBQL except within the expansion slot.
