I have two noobie questions, what is the maximum clock MC68000 based cores (Atari ST, Amiga) can achieve, and second what is largest x86 CPU architecture can be fitted into fpga?
Not a direct answer, but to give you an idea the Cyclone V FPGA it uses, at 110K LE, is the largest of any board at this price. Hobby projects can't mount this FPGA chip on a board because it requires special connectors/equipment (BGA). That has been a limiting factor for many projects... MiST and other similar projects use 25K LE boards (Altera Cyclone III usually), and the Zx Uno and Arduino FPGA boards use 9K LEs (Xilinx Spartan 6 usually). So it's really great that there is a commercial board cheap enough to serve as base for the MiSTer.
This FPGA is the best we can get right now and it's likely to remain the case for a while. In terms of size it's more than four times bigger than the MiST's Cyclone III, and it also has more advanced features like better clock control, and an embedded ARM processor in the chip that can be made to interact with it. So for example, in principle it is possible to have a core using the ARM chip but of course that needs a specifically developed core for it (which does not yet exist).
The extra breathing room should be good for developers who had to spend time optimizing their cores to fit the MiST. In the end development should be fun for people to spend their free time on it, so having a good and easy to use platform is important.
Props to Sorgelig for making this and sharing it. I'm getting a board soon to try it!
