PDP-11/44 mystery card

Hi Pontus, congrats on this acquisition. I had a quick look at the list. When looking at Expansionsl?da 2 (l?s) I frowned seeing the 11/24 CPU module there. Now, I don't now if you wrote them down in the order the modules are in the slots (like the first 11/44 CPU), but I think you better check all positions before applying power! Now, my Swedish is nill, but I think "l?s" means something like "loose" , "just a bunch of modules" put together in the expansion box, where the expansion box functions as a storage drawer. I use BA11-K boxes too as storage boxes ... never apply power! Sorry, can't be of much help here. AFAIK, the KG11-A "belongs" to serial comm cards and adds error checking on the data stream. My guess is that the M3110/3111 are modules that "seek" for a special character and generate a CRC for error checking purposes ... just a guess. - Henk.
