Re: Anouncement for the 40th Anniversary of the Sinclair QL in Dormagen (Germany)
Special thanks to organiser Detlef, to Urs for the history lesson and to Peter for the way forward and his last minute update of my Q68, despite some uncooperative Chinese hardware. Hi Bob, I hope your Q68 continued to work. That Chinese JTAG adaptor is in the recycling bin now. At home I have the ...

Re: Anouncement for the 40th Anniversary of the Sinclair QL in Dormagen (Germany)
Hi Prof, many thanks for coming, it was a great meeting! I think it is realistic that most of us would come again next year. • Could or do any of Peter’s current line of FPGA based offerings support a letter box style LCD panel of 400 x 1280 / 1920? Ideally, the panel would allow a VGA or HDMI input...

Re: A small QL
I may f wasted money on the Tang Nano 20K, but at the time the idea of learning Verilog seemed a good idea. Maybe the Lattice approach might of been a better idea. Hi Derek, please do not get me wrong. Nothing speaks against the GoWin chip to learn Verilog. My question was more about the advantage ...

Re: A small QL
Also see it for 61 € at Amazon and the GoWin chip on it seems already obsolete.Derek_Stewart wrote: ↑Thu May 16, 2024 10:10 pm The Tang Nano 20K development board, cost me £29, but the price has dropped to just above £23.
While the Q68 was designed in 2008 and the Lattice FPGA is still available.

Re: A small QL
I don't understand the hype around those chinese GoWin FPGAs. If I look at authorized distributors, they have already become more expensive than the Lattice chips used on QIMSI and Qzero. The Amazon prices for a Tang Primer 25K and the required extra modules are more expensive than a QIMSI Gold - so...

Re: A small QL
I don't sell my work, it is just hobby. Stephan has the permission to build the Qzero, that's enough.
No. Only my QLbase and QL-SD hardware designs are open source.

Re: A small QL
Well, let's first find out if Peter's qzero and latest work is open source or proprietary? QLbase will be open source, and can serve as example on how to use the Qzero on a different mainboard. The Qzero hardware is non profit, closed source. At the moment it lacks documentation and is only release...
Re: Sick Q68
With a big warning in the manual, if a user wants to try at his own risk, I find such an experimental feature acceptable.Derek_Stewart wrote: ↑Sun May 12, 2024 11:17 am Whiles the faster SD Card access for the Q68 was a good idea, the feature has caused all sort of problems.
But never should this be default on the SMSQ/E website.

Re: Double buffering?
Even if Peter says there isn't, here is a working example of how you can make the second screen usable in QDOS machine code programs. I didn't say there isn't. Just that I can not remember - which is a difference over 50 ;) I wonder how much room your procedure would leave for the actual code and d...
