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:
https://www.sinclairzxworld.com/viewtop ... f=8&t=3831
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
