50Mhz isn't close to enuff.
For me it needs to be at least 500 Mhz as a bare minimum for a new run. And have MMU + FPU.
If we sit around and do nothing we will get 500Mhz FPGA 060s in 4 years without any kickstarter.
If you want a 50Mhz 060 you can buy those right now. No need for a kickstarter.
If you want a 100Mhz 060 you can buy those right now.
Kickstarter is to make new things that don't already exist.
Another possibility is a bounty or kickstarter to make an ARM JIT to run Motorola bytecodes. You should be able to get 300Mhz 060 speed (without MMU) on a wide variety of cheap ARM cpus.
There is no 68060 JIT for iphones because Steve Jobs personally banned it.
But everyone is allowed to code 68060 JIT for ARM cpus for 10 other devices.
There are multiple 1.0+ Ghz ARM cpu computers (usually with 2-4 cores) in the $99.00 range typically with 1GB+ of RAM.
Or you can buy a top-of-the-line smartphone from Samsung or HTC or Motorola and get a 1.6Ghz to 1.8Ghz ARM cpu with 2 or 4 cores + 2GB RAM and uses hardly any electricity. They are much cheaper and more energy efficient than silly intel processors. But those smartphones have expensive 1080P or 720P screens built in so they cost around $600.00. But $600.00 for a 300Mhz 060 sounds like a damn good deal when I see ppl selling 80Mhz 060 cards with 64MB of ram for the same price!
If you are serious about a kickstarter you really need to find someone who can and WILL code an ARM JIT and focus on that. It is 1000x less risky and cheaper and more achievable than trying to get some lame cpu company to fab new high speed 68060s.
I have been trying to brainwash Mrs. Beanbag into coding it for us but I have not been successful yet. There are various ppl who could do it. Matt Hey, Rachy, whoever wrote the JIT for MorphOS, + a dozen other ppl.
I will pay $300.00 for someone to code a working FREE OPENSOURCE JIT that works on ARM. As proof it must be built into UAE and shown to work or optionally it must be built into a cheap arm computer and shown to run Amiga software. This is so if UAE source code is too hard to understand, then there is another way. For example, you could make it run on Raspberry Pi. But I am more a fan of the better ARM chips in the other competing computers such as Ouya, or any of a zillion other computers in the $99.00 to $250.00 price range. I prefer Cortex A9 atm. But if you don't like that then ok I won't discriminate against Rpi.
My offer expires in 1 year. But I reserve the right to extend it. I can't leave my bounties open ended forever and ever or I might get hit with a whole bunch of bounties all at the same time and not have enuff cash to pay them all at once. So I hafta keep things limited to something that I can GUARANTEED pay. I know $300.00 is nothing for all the hours of work you hafta put into the project. I'm sorry. I am dying and have little money.
If I was rich I would pay $3000.00 or $30000.00 to get things moving. Grrr! I want something to get done but I have little power :*(
