Cloning the DTV
I wonder how hard it would be. Given that the DTV seems to be finally attracting some quality productions, but is no longer sold at all (and even when it was sold, was a pain to convert into a "real computer"), it might be a cool project to create a little DTV on a mini-ITX type board.
The only questions I have are:
1. Is enough known about the DTV's internals to actually code the clone chips in VHDL/Verilog/whatever?
2. Would anyone buy such a creature if it were to become available?

Some facts of the for the 1. question :
I think the emulation of the CPU, the blitter and the DMA controller is nearly 100% accurate.
emulation speak for that. For example, the disk loader and the modplayer of DTV odyssey is very time critical.
Maybe for the video part of the DTV there are some strange tricks left.
The only way to get the emulation more accurate is to
write more special testcode or write more demos for DTV :->
for the 2. question :
A new hardware will be quite more interesting if is much more compatible with the original C64, which results in lesser compatibility for DTV software.

you can always run fpga64 ... which is *quite* accurate now (i would dare to say, more accurate than most emulators). |

That's C-One related, right?
Would be nice of there would be a DTV-alike spawn off based on the C-One. |

fpga64 runs on the c-one, yes...but it also runs on a few other boards (and porting to a different board isnt supposed to be terribly hard either)

:-P
Yeah, but the fpga source from Jeri isn't available.
I heard there was another kernal (afaik by a dutch guy) made. Maybe it's possible to use that as a base. |

Yay! We're getting somewhere ;-)
Maybe it's possible to use that as a base for a DTV clone. |

sorry, but to me that sounds incredible stupid :)
using an c64 fpga to emulate another c64fpga that kinda failed in several places but got additional features instead?
Id rather LOVE to see a proper stand-alone fpga64-board.

enthusi: like i said, the fpga64 core runs on a few other boards, you can call that "standalone" if you wish :) |
