C64 Reloaded ? (in Hardware)
Someone else noticed that 1st April entry at c64.sk about a new C64 in actual Hardware made by individual computers ?
Thought about an April joke, but then i saw this :

Anyone up for this ? :) |

For me it looks like pointless, no real advantages over original one. I would have wanted to see buffered sid noise mods and extra sid socket for stereo tunes. Devias sid mod looks way more interesting that this product in that area.
There seems to be extra components near video output so there might be some advantages over original design in video output quality.
Also I'm concerned about 9vac line for userport as theres just +12v dc going in.
So, my question is why? Explanation about broken pcb's is just silly :D |

what grue said about sid. i'd love to see a board with optimized sid sound quality, just like all those improvements lemming and devia incorporated in this. or maybe even included to be able to switch between 2 sids.
optimized video output is very nice though.
is this gets 100% compatible without flaws or compromises this might be interesting. |

Why not some clips so it's easy to add a heatsink (with springclips) to the sid/vic? :-)
these things i mean :

all voltages are there. i am curious though: what is it that you will use at the userport that needs it? :)

"To celebrate this, Individual Computers has prepared a limited production run of a new C-64 motherboard."

being 100% compatible is pretty much the only "must have" for this product. it is also why jens is very reluctant in doing any significant changes to the original circuit.
(i have updated that wiki page a bit if anyone cares :)) |

Is the 9VAC a true sine wave, or a crappy square one?
I might be interested in a board, but only if support for a second SID is added and the VSP-fix actually works. |

Quoting Groepaz(i have updated that wiki page a bit if anyone cares :))
Absolutely, please keep us updated. Details on the hardware VSP fix would be interesting too. |

According to Jens:
Quote:Der VSP-Bug ist ein address-hold-time-violation bug. Der Fix ist nichts weiter als die Stabilisierung der Adressen rund um die fallende Flanke von RAS.
The VSP bug is an address-hold-time-violation bug. The fix is just stabilizing the address bus around the falling edge of the RAS signal.
According to him it's not feasible to add that fix to an existing C64, as you would have to socket the RAM chips and also get some signals from the VIC. Nothing that would be an easily installable kit. |

i cant answer that (will ask), my guess is "not exactly sine, but not exactly square either" due to the circuit used to generate it. you are making me curios again though: what is it that you want to use that requires a perfect sine? :) |
