Interesting Interface.

Schematic can be found in the German forum:
https://forum.tlienhard.com/phpBB3/viewtopic.php?t=4628

Content of EPROM and typ of PAL (PAL16L8-4CN) can be found here, as well as a picture of one (parts) side of the PCB:

To know what it is doing and how it is doing this, we need just:

- The content of the PROM
- The configuration of the PAL

If you have an interface at hand, it would be great if you post a photo of the other (back) side.

Greetings from Mustermann
