While surfing the net, I found the website (https://erhardsigrist.ch/68000-2/) of Erhard Sigrist (aka Cluedo), who was part of a small Swiss swapper group called "SUPERRIDERS COPYSERVICE". Members were Cluedo, Psycho and Headracer.

They sent a service disk to their contacts (https://erhardsigrist.ch/wp-content/uploads/2018/05/SR_ServiceDisk_1.zip), containing a list of available software, a picture show and the "Fight Demo" (all in monochrome).

Are they and their service disk worth being added to demozoo?

We are not pre-selecting or judging any prods. We document history. So YES! Thanks for the find.
