@Loriano

I will talk to you before the final board design will be completed. We should design it in an enclosure-friendly way.

That sounds promising, I can't wait to start working on the next gen Minimig ;-)

What exactly is the limiting speed factor of the hardfile implementation? We just finished an internal version of the Minimig core for the C-One with harddrive support, working on a real harddrive (in my case, on a DeLock IDE flash module). Without optimization, our performance is 545k per second (see pictures on www.c64upgra.de/c-one ) - a good 20% faster than what's shown in the Youtube video.

There might be room for improvement as we speed up the CPU, but I don't expect much more, as the CPU is just a plain, 68000, sharing the bus with the chipset and another 68000 CPU.

Minimig on the C-One now has 11 megs of ram and a harddrive. An RTC might be an idea now :-)

Bloody hell!  That's good news!  I certainly don't mind using one of my spare 2.5" IDE hard drives on my C-One if it works!  Only a couple more days until I get home and then I can finally mount that C-One in a case and start testing it.  :-)

RTC would be nice, but I'll tell you want would really get me going... being able to access those clockports.  If you could manage that then the C-One Minimig could have a Subway USB device attached.

RTG via a PCI graphics card would be the ultimate wet dream.   :-)

Are you still beta-testing that core with hard drive support or has it been released?

Cheers,

Edit:  I just found your post on Yahoo quoted on Minimig.net and I'll be happy to wait for your CF support like you suggest, rather than risk my C-One board to any reflashing or soldering.
