Is there enough documentstIn about what is in the original chips to figure out how to clone them?


Most of it's in Tim's head and they basically only work because of observed behavior, not technical specifications. The RAM for example runs WAY out of spec, but after experiments it proved to work in practice.

That's why there was never a PAL version. It would have been almost as much work to remake it in PAL timings as making the original NTSC version in the first place. It's not just an adjustment like most people assumed.

I'm sure the source for all the programmable chips is still around, but this was way before Verilog. I think the whole Flyer (including programmable chips and DSPs) is in the OpenVT distribution although I could be mistaken.

I think it would be easier with the fast FPGAs available today. You could focus on what needs to be done rather than finding a hack that makes the timing line up.

I'm sure it's possible, but it would be a major undertaking and would it be useful anymore?

If it's for preservation I'd start with the software. The cards are as easily available as any Amiga device ever made and (inexplicably) rarely seem to fail.

At least the software could live on with new features and on newer platforms.

In my opinion, the Toaster/Flyer was one of the best creations made for the Amiga. I know that much of the processing was done on the Toaster card but the Amiga did give it a long life.
My system still runs flawlessly after all these years but truthfully I hardly ever use it any more other than to show people what the Amiga was capable of.

I still use a Newtek product called Speed Edit for my current HD video editing on a PC but it is not a live switcher so that part for me is lost.


If you are looking for live switching, we still sell a huge number of TriCasters. It's a decedent of the Video Toaster.

It's similar to the complete Amiga/Toaster systems that we sold back in the day, a turnkey system as opposed to a card and software.
