I’d like to try reading some values from a sega game console expansion port. It’s a M68000 CPU and the system runs at 5v. Could I use the AU or CU Alchity boards, or a some other FPGA to watch for specific values on the address and data bus on the expansion slot. Is this possible with this FPGA? Is there some other better suited FPGA?

As far as we are able to tell, Alchitry boards are not 5 volt tolerant.

You might want to double check on the [[Alchitry forum](https://forum.alchitry.com/) to see, they should be able to tell you for sure over there. :-)]([https://forum.alchitry.com/](https://forum.alchitry.com/))
