Vampire 600 more cores..
So I finally got my USB-Blaster today. Since I had core 0.1 loaded, it only has 5 MB of fast ram. Wanted to try core 1.0 which has 64MB.
Loaded it up fine, but its very unstable, as its described so no news there. What I was wondering is; is there anyone else making cores for this baby? I'd like the stability of 0.1 but with at least 8 MB memory. |

Majsta switched his interests to bitcoin instead of charging 50 euros more for each Vampire and enjoy bank account filled with cash. I would rather pay 140 euros for nice accelerator than 90 for half working crap. Idea was right but nobody will develop fast accurate core for nothing. Sorry but I don't understand working long time on the product that people want and willing to pay for it, than selling the product with minimal or no profit just to drop everything coz I need money. I wish Majsta all the best, he was always honest and kind.

It's really sad, think a lot a people would pay extra for there vampires so he could make a nice profit.

Yeah, I was wondering about his bitcoins venture. Sounded like a very bad idea =(

There are actually a few people left in the Classic scene that have the skills to finish this, in fact I was actually talking to one of them at the local Amiga meeting the other day.
I don't know all the details but apparently there are various 68k cores in different states of development that could be used. I guess the currently problems are something to do with the bus/timing logic and not the core itself? It's a real shame to leave the thing so close to finished. If this A600 board was fully developed (eg fast/compatible and stable) then an A1200 board wouldn't be far behind. |

You know, some people said making Amiga FPGA accelerators was a bad idea Just let the man do his thing, the least he'll gain is knowledge.

He prove something and AFAIR He open source thus i see no issues to fix/improve core - as i don't have A600 i was not interested in Vampire personally (as Majsta stuck on reimplementing HDD functionality from Gayle for A500 version).
Thing can be for sure improved: less cycles per instruction, deeper pipeline, cache, new instructions, higher clocks etc only FPGA resources are limitation. Perhaps some startup on Kickstarter for this? |

Don't worry, Majsta did not give up
Amiga development is only on hold until he sorts out the mining rigs. It's not like he has to participate in mining actively He'll be back at his Workbench soon enough |

Actually it's GPL so anyone with mild skill in VHDL can modify sources. For your information the file you should check is Vampire_600.vhd; there you can make it work with more RAM (so use 32bit zorro space for autoconfig) but it won't get any faster through that. Only that "unstable" core is made for speed. It's kinda sad - majsta gained quite large pre-paid beta testers to catch and resolve all bugs in softcore yet just released sources and went bitcoin mining :/

Wow, cool. I was thinking about caching within my Zorro SDRAM card, now will check out your TG68MiniSOC project

I was more wondering about this Amiga meeting you mentioned. Is it some kind of Amiga user group here in Melbourne? And if so, how can I get in touch? |

P.S. I left a message on the Apollo forum about the problems but Majsta seems to be AWOL. |
