I bought an Altera Cyclone FPGA RCQ208 development board (clone) on eBay a while ago.
To make it work, follow the instructions on the multicomp webpage: it’s just a matter of cut and pasting the desired components into the file ‘multicomputer.vhd’. Then, with Quartus, you must change the device and change the pin assignation for your particular platform.
To change the device, on Quartus’ main menu, click assignments -> device and select EP2C8Q208Q; you will have to scrap the current assignations since the pins will not be at the same place as the original project.
To change the pin assignation, on the main menu, click assignments -> pin planner.
The result is this assignation for my FPGA board:
set_location_assignment PIN_14 -to rxd1 set_location_assignment PIN_15 -to txd1 set_instance_assignment -name WEAK_PULL_UP_RESISTOR ON -to rxd1 set_instance_assignment -name WEAK_PULL_UP_RESISTOR ON -to rxd2 set_location_assignment PIN_23 -to clk set_location_assignment PIN_27 -to n_reset set_location_assignment PIN_207 -to ps2Data set_location_assignment PIN_208 -to ps2Clk set_location_assignment PIN_8 -to hSync set_location_assignment PIN_10 -to vSync set_location_assignment PIN_175 -to sdMISO set_instance_assignment -name WEAK_PULL_UP_RESISTOR ON -to sdMISO set_location_assignment PIN_173 -to sdSCLK set_location_assignment PIN_171 -to sdMOSI set_location_assignment PIN_170 -to sdCS set_location_assignment PIN_64 -to driveLED
