Hi all, I think this is probably an appropriate list to ask. I've been considering new ways of storage for my c64. I want it to be very compatible to a 1541 -...
... Cool idea. For those of us who already own a C-One, using it as a 1541 emulator for a real C64 would make an interesting gadget for sure. It already has...
Hi David, I've not seen any 1541 in FPGA project, only software solutions. A good start would be taking the 6510 core from my fpga64 project and the VIAs from...
... One line of the IEC bus needs to be bi-directional, but Jeri made it one direction only. A few weeks ago, she came up with the CPLD update, but I decided...
Hi all.. I ve read all the messages about 154 emulator.. anyway, are there any news regarding the fpga pci board (Jens?) ? So far I know it will give more...
Hallo David, ... On itself it sounds cool but I have been workong on a real 1541 with a IDE interface. The problem is not the interface nor accessing it but...
... [snip] Hi Ruud, First off, I love your page. I saw it a couple of weeks ago, and your hardware projects inspired me to think about these things. Well, the...
Hello, are there some more informations about development-status (version-history, future-list) or bug-reports? I've added some disc-images (.d64) on my...
... That's a known bug in the FAT routines of the C-One system flash. Just copy all the files to your hjarddrive, re-format the CF card and copy all files...
... solves it. And solving the problem at the root? http://sourceforge.net/projects/c1boot/ seems to be dead since 2004. I think the idea was good. Maybe I can...
Moderator, if this is not appropriate for this list, please delete and direct me to the proper place for this sort of question. Now, I'm modding the current...
... The 65816 is on the same address and data bus as the memory and lots of other parts of the C-One mainboard, therefore it will most probably not run at full...
Hi, A little problem with the C-One is that the 65816 is sharing the bus signals with the 128K SRAM. So for enabling the 65816 it would be easier if the SDRAM...
... Well, once I'm done modding, the core won't have much compatibility anyway. I'll have a try at using the SDRAM then. ... Ooh, I hadn't considered that....
Hi, nice to hear about such a thing. The pinouts should all be in the schematics of the C-One, which you can find under www.c64upgra.de. Expanding the color...
Hi All, Currently I'm working towards a new release of fpga64. As I don't have access to a (reliable) working c64 at the moment so I ask the group. (yeah I...
Hi, Somebody asked me for the program to test this. This one does the trick: 10 FOR I = 0 TO 255 20 POKE 56331, I 25 X = PEEK(56328) 30 PRINT I, PEEK(56331) 40...
Hi, Anyone have ported FPGA64 to others boards? I have one Altera DE1, and one Xport 2.0 + Gameboy Advance, but I am not engineer and just started playing with...
Thanx Chris, could you please run one other test for me? 10 poke 56331, 0 : print peek(56328) : print peek(56331) 20 poke 56331, 18 : print peek(56328) : print...
... I ported an earlier release to the Altium Nanoboard NB-1. I've been meaning to update to the latest version and port it to my latest hardware... Regards, ...
Hi All, I've made a new release of my PAL/NTSC C64 core called FPGA64. It's version 0.19 released on 20070508. Lots of CIA related fixes. release notes: ...
Hi All, I've made a new release of my PAL/NTSC C64 core called FPGA64. It's version 0.20 released on 20070512. Because the CIA timers are correctly working in...
Dear all, isn't it possible to use some space in the upper area of the 128k RAM for the color ram? I think, the upper 64k are only used as ROM area, right? ...
Hi Andre, ... There is about 40k free in the SRAM. Putting the color ram there takes 1 extra memory cycle so the VIC-II code needs to be changed so it allowes...
Hi, You may know this CF filesystem bug : when you add some files, they are not appear on the file-selector (mainly on the CPC core). I remember that Jens...
