Hi list, as promised yesterday, the updated schematics of the Instant-On board are online, and they now contain a basic description of what the config CPLD is...
Hi list, Peter has just uploaded a new version of his C-One core development manual, and I have also uploaded it to the C-One website www.c64upgra.de/c-one ...
Hoi group, I just uploaded a new Chameleon (preview) core. Just as Jens already mentioned there were a few problems with the joysticks. This has been...
Hi all, Excellent work. Just tried Peter`s new core and thought I`d pass on my findings. On start-up of Chameleon core, my CRT goes into HOR: 48Khz VER 73Hz...
Hi, ... Thanx ... Correct, that are the frequencies for the 800x600 mode that the chameleon core uses. Please try the 800x600_test_v3 core from my website. If...
Hi Peter, Thanks for that. My mitsubishi is a Diamond plus73 :) Tried your test_v3 core. Result is slightly different. Picture is more compressed, Thick, black...
Hi, ... I've searched a bit, but didn't get a clear Hz rating for this monitor (some sites state 66Hz but that is rather low), but it seems limited to lowish...
Thanks for your help Peter, Much appreciated :) I`ll start looking for a new monitor. Should be able to find one relatively cheap now at car-boot sales. Roger....
Hi Peter, I just made a very interesting discovery concerning monitor sync problems I had earlier. It seems I won`t need to hunt for a new monitor after all :)...
... The device might invert Sync signals. Some monitors take the sync polarity to pre-set the PLLs. Peter, would it be possible to cycle through the four...
... Thinking of it, this should be Ctrl-Scroll-lock, so it won't be pressed accidently. The Indivision AGA flickerfixer also has the possibility to invert sync...
... Yes it is possible, but I won't do that. There is already a register in $D0xx that allows control over the sync. So like I wrote before already: in the...
... This reminds me of something I forgot to report - Peter's v3 test core works much better on my monitor if I invert the vsync signal and rebuild the core....
Hi, Thanks for that, You too. Hope my info was of some use :) I will have a much better weekend now that my sync problem has gone. Roger ... [Non-text portions...
Before I start trying to reinvent the wheel... I figured I'd ask: Has anyone looked at porting the ZET - http://zet.aluzina.org/index.php/Zet_processor core...
Hi, ... Probably not, never heard of anybody that was working on it. ... Some info is available here http://syntiac.com/c_one.html The document you searching...
Thanks... found it. Very nice doc btw. Well... guess I better get started. :) see if I can get something ready for when my board arrives in the mail. -Blair...
I had the same issue trying to go to Newboot. It turned out, after lots of hair pulling, that I needed to place additional load on the PC power supply (in...
Ok... I've gone over the Pong demo... I've had a few cracks at porting some existing code previously writen for the same FPGAs. And I'm all ready to go once I...
As the pong demo is a design for the 1k100 FPGA. There isn't much (if any) difference between BigBoot and NewBoot. You might need a updated gbridge file and...
Ok... the newbie has Pong displaying. Still under BigBoot. But it works. I'm trying to get my head around this stuff... but all of the examples seem very...
Hi, The 'issue' (problem, challenge etc) with a extender board/cyclone III design for the C-One is that you need to create and compile 3 fpga projects to be...
Hoi Group, I've compiled a new FPGA-64 version. It has swapped joystick ports and has a workaround that fixes the X/Y pot swap on the C-One PCB. Just as with...
I'm going to offer a Bounty/Reward/Bribe to you folks out there. I've been asked to demo the C-one to my co-workers who are all FPGA designers... for video...
... Sigh... if only the bounty were enough to cover the cost of a C-One, then I'd definitely buy one! ;P And port my other projects to it... Regards, --...
Ok... I'm getting a bit too confident I think. I've managed two (yes 2) working cores and I start getting ahead of myself again looking at REAL Cores. :)...
