[QuadList] QuadList Digest, Vol 19, Issue 11

The Sony BVH-1000A  and the BVH-1100 and 1100A in the table top configuration were packaged so that the two card cages were on the back behind the transport. These were hinged on one side so that, if you took the side panels, handles, etc. off, you could swing the electronics chassis around to be beside the transport for maintenance.  Sony had a kit available which put rack ears on the electronic chassis and provided a series of extender cables so you could mount the electronics off the transport.  You also had to take the feet, etc., off the bottom.  Most people chose to do this and to mount the transport in the top of a rack, with the electronics and the BVT-1000 or BVT-2000 below that, similar to the pictures from NBC.  You could also get a kit and mount the control panel off the machine or mount an accessory secondary remote panel somewhere else. This used the Sony CCJ-10 cable, also used with their portable U-matic gear. Sony used a proprietary serial bus control system that wasn't simple to improvise with a panel and some pushbottons.
    They also offered some stand alone repackaged mountings if you didn't want to rack mount the machine.  One of these was the "Tea Cart," which was shown in a picture on this group recently. This was a roll-around rack, about four feet tall, on which you placed the transport assembly, with the electronics mounted below.  This then parked inside a housing which contained a picture monitor, speaker system, and WFM and V-scope.  There was also a side by side console that took up about as much floor space as a VR-1200. I never had my hands on one of these, but I have been all over the others.  The RCA versions of these machines also had most of these mounting options available.  The the 1000 and 1100 were relatively clumsy no matter how you packaged them and the later Sony machines the BVH-2000 and BVH-3000, etc. styled more after the Ampex VPR form factor were much more practical to work with and on . . .

> I think that Sony did offer a 1100A with the electronics available to be mounted in a different place. I think that you have one of those machines. The machines were not that easy to troubleshoot with the constant going from behind to front if they were in a set of racks. They got smarter with their later series of machines. 
 
I offer: 
 
NBC did this with their BVH-1000's, starting in 1978:

The electronics chassis were moved from the back of each machine to in front and below it by installing extra-length cable harnesses.
