So is there any new cores or any news on the c-one? Seems very slow. Nothing for weeks. Did something happen I do not know about? [Non-text portions of this...
... I moved, Tobias wrote a new startup (to be published this week), and Peter was busy on a different project (to be published in fall of this year). Just...
Be sure to post information about the changes over at c-one.net. From: Jens Schoenfeld Sent: Wednesday, June 04, 2008 3:56 AM To: cone_cores@yahoogroups.com ...
I made the modification on my board (the BA-Signal on Cartridge Port). Everything's fine, but I still have problems with cartridges. I couldn't find...
... This might be related to the C64 clock not being exactly the original PAL C64 clock. Fastloaders require pretty exact clocking, as emulation shows: Bero's...
Hi, If you get to the menu on the FC-III and AR cart then atleast the BA mod is done correctly. And yes Turbo loaders can be picky. So one source can be...
Would it even be possible to replicate the white noise generator with just logic? That's part of what makes the SID special. From: Chris [xc8/Bronx] Sent:...
I'm not familiar with the internals of how it was originally done in the SID, but the answer to that is a solid yes. Pseudo-random noise generators based on...

Hi Chris, Actually it is a lack of 'logic-space'. I think the last core is at 97% usage of logic gates. There is still some fpga-memory free, but that doesn't...
Hello, thanks for answering so quickly, so I just know that my mod was successful. This is, what I really wanted to know. No problem if not all things are...
... snip. So to fee up space, can we get rid of the 6510 in the fpga, and use the 6502 in the '816? and just put h/w inside the fpga that is needed to keep the...
Hi, Yes, using the 65816 will free up about 20% of the 1k100. However I'm not going in that direction as it loses compatibility with the original c64. I do all...
... Of course, but the 6581 is not ready available. I see some of them on e-bay, but I read some are defected or fake.. As I see there is a SID clone (FPGA)...
Hallo Allemaal, It has been a while since there was an update. During a long 'retro' weekend Jens, BeRo and I had the chance to torture the C-One with various...
Great news! Can I get a volunteer to put these bits up on C-One.net? From: Peter Sent: Thursday, July 24, 2008 4:09 PM To: cone_cores@yahoogroups.com Subject:...
Hallo Peter, thanks a lot for the new core. Unfortunately this version seems to break compatibilty to some vga monitors. :'( On my Eizo F56 the picture looks...
... That will be pretty much impossible, as the monitor frequency is fairly closely tied to the actual VIC timing. Since the whole computer is now slowed down...
Hi Dirk, To simulate the closer to correct clock frequencies I use different clock dividers. These break the scandoubler developed by Tobias when he initially...
Hi Peter, just tried the 0.26a and it looks much better.Nearly similar to older versions. The picture is much brighter than in version 0.26 and on the Sony it...
The server for C-One.net is physically moving to another city today. The ISP is scheduled to have service enabled when I get there, so hopefully the server...
Hi Peter, just to let you know: i had the same problem with a Belinea 17" TFT. I installed 0.26a and have now a perfect bright screen. best regards retrofreak....
Hoi, In this release a bugfix for the buslogic module that allows the MMC-Replay cartridge to be used on the C-One. You also need the BA-fix on the PCB for...
Excellent news.. Too bad that I dont have the c-one with me now, to check the new core. BTW, I have some questions about the new fpga extender, I suppose I can...
Hello Peter, great work! If you like I can free the DMA-Line in my new C-One Startupsystem. I will also use a direkt Line for the SID-Clock. The 1K100 pin163 ...
Hi Tobias, Are there any details about the fpga extender? As i read, there are 2 x 68000 on it, so i suppose its possible to "emulate" an Atari ST ? chris ... ...
Hoi Tobias, Freeing the DMA line would be great as it allows REU cartridges to function! The SID clock is not critical as it is quite slow with 1Mhz. But if ...
Hi Chris, we diskuss details on a german webpage: http://www.forum64.de/wbb3/index.php?page=Thread&threadID=25508 But I can't tell that in english. To...
Hi, I don't speak German, but by the "rough" translation of babelfish, I understand from that forum that the fpga-extender is using the only the geekport , i...
