Unused power of c64 config
Hi,
I always wonder why nobody ever released something that will require four 1541 drives to run (5x 6502 running in parallel). Serial bus is of course slow but if You have large computations to do time to transfer data shouldn't be a problem. You can also use parallel cable instead of serial and then calculations/transfer ratio is very good:)

Perhaps not exactly what you're looking for but close:

hmm, I want to see demo running on a STANDARD c64 configuration, which is 1x c64 + 4x 1541;) whithout any network. |

I'd actually want to see a demo, game or tool running networked over a drive. 4X 1541 demos would be cool aswell, but would for starters not beat 6 SID-voices (1X8580, 1X6581R4). 2 C64's are probably more common than 4X 1541's amongst the audience too. |

2f: that was done a few times already :) |

I'd gladly test a 4-drive setup, no problem setting that up right here :P
Would be a nice experiment. |

I know there have been some games testing out this kind of 1541 networking solution (I saw KF and one of the Oneway-guys doing it at a Floppy, amongst other things) but I haven't seen a demo or a 6 SID-voice synchronization, or even a tool utilizing it. If you know of something like this, please let me know. |

Double uses 2 c64s, the sid is 6 voices I think, but there's no real sync (press key at the same time on both c64s) |

Same with Multi-Scape Demo which should be run on 4 c64's simultaneously, no real sync here either though. |

All those examples are not what I wanted:) I want a power of 5x 6502 on one screen (I don't care about 2 SIDs:)) So, who will do such "world first"?:) H2SO4? Groham? Krossbow?:) |

imho if the stock setup is not enough for you then you should watch demos on amigas/pcs. |

I figure that might limit the potiential audience too much. One 64 and a drive is what most probably everyone can come up with. 2 drives maybe, but then it's getting harder. The excess drives are usually stacked away in the attic for future replacement. ;-) |

Oswald: Pffff, stock setup is C64 without drive. Why don't use full power of stock C64 with 4 drive's instead of 1? PC demos are boring. What is Amiga?;)
Steppe: Today everyone has PC with emu so the audience is not a problem, also I think that party organizers should allow configuration proposed by me. |

@Mr.Ice: I really suggest you do it if you're so interested in it. ;D I mean, u ARE a coder and communication over the IEC bus is NOT rocket science. Do it! |

@burglar: dont you remember what demo it was that was released on one of the x parties? they used two c64s which where synced via IEC ... i had a quick look at csdb but couldnt find it :/
i also remember something from JCH, which was probably released at TP. no details either =)
and there were a few more, some synced via IEC and some synced via userport, and also one or two used a joystick port connection. |

FD-Tools V1.05 hasn't got a large audience too, but that didn't keep the creator from making it... |

I expect hardware makers to make software to facilitate their product to be useful. |

Hmm, I wonder if there wasn't some Mandelbrotset-Creation-Utility released by some German Mag (64er, Magic Disk?) in the late 80ies that used at least 2 floppies to do calculations for a mandelbrot set...
Unfortunatly I do not remember the name. Wouldn't help that much, cause it will not be here on CSDB as it was no real scene release (Grp: correct me if I got the rules wrong ;))

C64 + 2x1581 is almost as likely combination as C64 + 4x1541 and gives you double drive memory with half the transfer hassle. But why use only couple of drives when you can easily* connect 31? That would give you ~63 MHz and 312 KB.
(* You may have to get rid of some pull-up resistors to allow driving IEC lines down, but if you are ready to use parallel cable then small modifications like this should be ok. Even better would be using burst mod to use 60-70% of transfer time for something else.) |
