I did wonder about that port. I thought despite the funny warning about not using it, maybe it supplies +5V on some of the pins like the Amiga used to. Could be a risk of burning something if you hotplug. Perhaps more than likely only intended for the vendor to use.

Thanks p2-mate. That seems to be exactly the system I have and it even seems to document the jumpers. I’ll have to have a play when I get home and see if there’s anything else I can get out of it. Without the hard disk working all I get is a m68k debugger/ OS/9 makes a lot of sense for an embedded system too.

Wow such great sleuthing!

Looks like it maybe this machine http://kws-computer.de/ftp/Delta/Homepage/pdf/pro30.pdf

https://web.archive.org/web/19981201194423/http://www.kws-computer.de/systeme.html says they usually used os/9 on m68k systems.

Amazing absolutely nothing specifically turns up at all. Even the UTZOO archive has 0 hits.

I suspect it’s an embedded controller for some kind of car parking scheme. It’s the best I could find on it.

The lack of SN’s and product parts makes me believe that it’s a custom OEM solution that isn’t off the rack to normal users. I do enjoy the port that specifically says to not plug anything into it.

Here’s some pics.

I’ll take some pictures and post them shortly. In Kiel apparently and I suspect it was used in embedded system as the company Designa seem to specialise in automated systems. But I can’t find anything out about it. It “reminds” me of an Amiga but it obviously isn’t. It’s an EC030 @ 40Mhz and has a PGA socket for what I would assume to be an FPU (68881/2) which isn’t populated. So no MMU and from memory I think early SUN’s used their own MMUs and not Motorola chips. It has a floppy controller, SCSI 1 controller and a whole bunch of serial I/O. It also appears to have a PCMCIA socket. Unfortunately although the SCSI drive spins up, it hangs every SCSI bus I’ve connected it to so I suspect the drive’s controller board is faulty even if the mechanics are OK.

Take pictures! I can’t find anything about this system. What city in Germany? Maybe it’s an East German SUN-3 clone?

I’m positive it’s going to be interesting!

On another tangent I’m currently hacking on another SUN-2 emulator! I’ve been taming it a little for Win32, and I have it running on i386&ARM!
