Hardware notes:
PCB named FR009D

main readable components:
HD64F2318TE25 MCU (H8S/2318 core with 256 Kbytes internal ROM)
32.00 MHz XTAL
Altera Acex EP1K10TC144-3 FPGA
Altera EPM3032ALC44-1 CPLD
2x CY7C109B SRAMs
ST3232C RS232 driver
2x 8-dip banks

Not much can be done until the MCU is somehow dumped.
