RLV12 placement in H9278-A question

As you've probably read in a previous reply, it doesn't really matter what type of slot it goes into, as long as you're not interrupting the path of a 2-board set. i.e., don't try to put it in between the boards of an RLV11. Now that I think about it, I guess it's a little moot, since you're in an 9278-A backplane, which only has 3 CD slots. The only way you could even use a 2-board CD-interconnect (such as the RLV11) is with a single-board CPU with on-board memory, such as an 11/53 or 11/93. Otherwise, your first two CD slots would already be full. ;-) One thing that has always made me a little paranoid about the RLV12 is the heatsink for the TO-5 transistor. It's very tall, and it sits VERY close to the boards above it. Be careful if you install the RLV12 underneath any dual boards. A little bit of warpage, and. . .
