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

wouldn't a coprocessor to to all the I/O make more sense, especially if it could do hardware debug of your cpu/memory ?

That would go in the FPGA. I don't know of any practical way to interface old chips to DDR3 and PCIe without an FPGA. Pretty much any existing soft CPU core you'd like could be used for a "service processor". I'd probably use a RISC-V, because the tools for that are in reasonably good shape now,. Xilinx even provides a MicroBlaze V core and tools in their software.

@brouhaha @bitsavers LPDDR3 perhaps?

Whatever kind of DDR3 is supported by the FPGA MIG.
