Does the world need a new single-board computer design with an MC68060 CPU?
I'm thinking about 4GB of DDR3 DRAM, one serial port, one M.2 slot for an NVMe SSD, and one Ethernet port (probably 1Gbps). Not intended to be software-compatible with any existing board or system.

Same question, but various 32-bit RISC processors? MC88110? Am29000/Am29050 (pin compatible)? Intel 80960KA/KB/MC/XA? TI TMS34020?

@brouhaha I’m still seriously thinking about building a FPGA ‘040 Classic Mac board that takes “modern” DDR3 RAM, USB keyboard, NVMe SSD, etc. and hopefully can be clocked well above what a 68k could ever achieve.

If somebody wants to implement an interesting CPU in a FPGA, I have a complete netlist for the Rational R1000 "Ada" computer...

@phloggen @jpm
That does seem like an interesting project. Do you have a complete Rational software distribution to run on the machine?
I had a friend who worked at Rational back then, and I always wanted to play with the machine, but never had the opportunity.

Yes, we have a set of diskimages of a running system, and also a software emulation which works:

But it would be so neat to be able to build a 1:10 fpga+rpi driven scale model for desk-top use :-)
