Got MIKBUG up and running on the EP2C5-DB card which implements Grant's original Multicomp hardware design (defines which pins of the FPGA go to which I/O in a "standardized" way).  The GitHub code is here.  Running with external SRAM (32KB used out of the 128KB SRAM part). 

A jumper on J8 provides port selection between the Serial port (on J5) and the VDU (VGA output and PS/2 input). Installing the jumper to the adjacent ground pin routes I/O to the Serial port. Removing the jumper routes I/O to the VDU. In the picture below the Serial port is wired to an external FTDI card.
