Hello. Couple of years ago while looking for B&O test equipment, I came across this very mysterious unit (bought here on Beoworld, shipped from US in 2018). It has the red serial number label which I've read means it was owned/used by B&O themselves, and/or being a prototype/pre-production unit. It's branded as "BeoCIM", which I am not sure what it stands for. Simulator? Searching the name brings up absolutely nothing. The front panel has a number of I/O ports: Login to view image On the rear is just an IEC mains input and a serial port (of which I have not been able to get anything out, although my testing was only brief). There are two EPROMs inside, I've dumped the contents. The only readable string I could see was "1.21 22-apr-98 MSH" which matches the firmware version sticker on the front panel. The seller provided me with this insight about the unit:

The unit came from our offices in Chicago (I work for B&O) when we moved to a new location almost 10 years ago. We were going to throw it away since no one is testing anything analog any longer, but I stopped that thinking maybe we would need to use it still one day. We'll that day has come and gone and no one needs/wants it any longer. I figured someone who is collecting or repairing old kit would want it vs. feeding it to the trash compactor. I am not sure on weather or not it runs on special SW, but that would be fair to assume. I guess you'll know once you connect into the port. The unit is about 21-1/2" long and weighs a little over 14 lbs not in packing box. The machine is 220v as was most all of our test equipment when we had the facilities as B&O were not going to waste money converting the natural 220v equipment to 110v. I put the sticker on the unit so no one would forget that the unit is a 220v. Unfortunately, my knowledge on that product ends at what it is. When it was in a working environment it was on lab desks in a rack with scopes etc. I don't recall something needing to be master connected to the unit, but I honestly have no idea. I know it was primarily used in the AvantCRT/AV9000/MX/BSys1 days.

Our best guess was that this might be something do with testing TV chassis' during production, but it's just a guess. Couple more pics from the inside: Login to view image Login to view image Login to view image I can't imagine these were made in huge numbers, but for that it seems quite well-built. The case appears to be a generic off-the-shelf plastic case. I'd be most grateful to hear if anyone can shed any light on what these units are and how and where they were used. This has been sitting on my shelf for years now and I am hoping to have another go at cracking it's mystery at some point, but so far I've come up with nothing.
