I am told they're fairly rare -- I've got a couple of them though.
There's info on it in the Options and Adapters TechRef volume 1

It adds 6 (8 bit ISA) slots to the machine (there are 8 slots in the
expansion unit, but one is taken up by the receiver card, and you lose a
slot in the main unit for the extender card). Not all cards can go in the
expansion unit either -- IIRC graphics cards have to go in the main
system, and you have to set the DIP switches on the extender card to
indicate how much (if any) RAM is in the expansion unit rather than the
main system. Standard I/O cards can go in the expansion unit without
problems thougk
