Motorola 68060 FPGA replacement module (idea)

[mongo]

Indeed, and I've been very excited about that. It's basically what I imagine for this discussion, only with a 68000 plug on the bottom rather than 040/060. It's not exactly shaped like a 68000, it has level shifting to be 5V safe, has power and memory onboard. But very much the same idea. He's working with the TG68, which has had some issues to work out to fit onto a standard 68000 bus. I'd really like to see the Suska 68000 code in there instead, as I think it would more readily fit the standard bus than the TG68. (Though I understand that further work on TG68 core is improving that as well, in addition to enhancing to 020 compatibility)

TobiFlex had the TG68 core running on an A500 about 3 years ago.

Lot's more chips to source, route, solder, and debug. I prefer just one FPGA and done with it.

You can get one of Xlinx's Zynq-7000 devices, which is basically an FPGA with a dual core ARM Cortex-A9 all in one chip.

edit - these are way too expensive!  You are still better off with a $50 x86 CPU.

The XC7Z010 is $63.75 in single quantities.

sounds even better perhaps, a x86 cpu module for fpgaarcade?? there would be no doubt about interface, and the original amigas might stay what they are, which is what im fine with.

Better to just do a FPGA on a PCI card and put it in a PC.

The 040 has less FPU instructions, the 060 is the first to drop integer instructions.

The 030 dropped CALLM and RTM that were present in the 020.
