Long time Amiga user, first time poster :-)
I've been having a look at FPGA information for a few months to catch up on what is going on in Amiga Vampire land.
Personally I'd love to have an Apollo Vampire Quad G5 Power Mac. Or perhaps a pretty PPC iMac Apollo Amiga. I'm sure the Vampire Amiga could suck the remaining usefulness out of that well made, but now very cheap hardware!
From what I read, you'd need to use a Cyclone family FPGA card, either III for the old or V for the new. There are plenty of those around the place. I was eying off a nice used Stratix GT card from a cloud data center till I saw that even upgrading from Cyclone III to Cyclone V has been challenging. I was thinking it could fit a lot more than just an Amiga on its 500K LE's.
Those now obsolete PowerMac's are going cheap. It would be nice to run CyberStorm and also 10 year old Mac software instead of 20 year old Mac software.
I wonder if the Apollo team may consider selling a download only version...
There may also be need for an Amiga port card which talks to the FPGA card over the PCIE or PCI bus which could act as a dongle if the Apollo team were worried about funding otherwise drying up due to our other traditional occupation of piracy ;-)
Maybe add some extra audio / video bits and make a Vampire Toaster card for utilising the NewTek stuff!
I'd imagine it would also be pretty cool to be able to do Amiga, Atari and PPC Mac graphics and sound out of one cheese grater quad PPC box.
