You can run a PicoRV32 on a dirt cheap Altera EP2C5 Cyclone 2 board. I have the RioRand® EP2C5T144 Altera Cyclone II FPGA Mini Development Board ($23 on Amazon

You can run a PicoRV32 on a dirt cheap Altera EP2C5 Cyclone 2 board. I have the RioRand® EP2C5T144 Altera Cyclone II FPGA Mini Development Board ($23 on Amazon). You'll also need a clone of a USB blaster JTAG cable, which goes for $10 or less.
