I am curious if anybody has documentation on the MIKUL 6809-5 PLC boards? It is an EXORbus based processor card (like the Motorola EXORset, MEK6800D2, or MEK6802D5) made by TL industries as an industrial furnace controller. It is fairly unique for a PLC because it has an MC6847 Video Display Generator (like the CoCo, MC-10, and Tano Dragon). I had some luck getting it to boot with the firmware that came with a MIKUL 6218 memory board, but I could use some more info on the memory map, etc., so I don't have to reverse engineer it before trying to port software to it.
