Rapport PCjr expansion chassis

The PCjr in question with the expanded memory is only counting
up to 128 when it POSTs, so I am pretty sure that the expanded
memory isn't getting any power at all. If the memory would
appear during the POST, my life would be wonderful. My other
extended PCjrs POST past 128KB.

So are there any Rapport Drive II owners out there that want
to tell me what the external power supply looks like? Does
it output the same as the PCjr power brick, or is it a different
beast?

The Rapport looks like a pretty neat device. The standard
PCjr diskette controller can only support one drive. They
use the standard controller, but they "borrow" some of the
lines on the floppy cable and run it through some additional
logic to add two drive support. It also looks like it has
a parallel port and a clock/calendar on it. It's also got
a switch labelled "PC/PCjr" - it either disables all of the
addon crap, or it adds a feature that I'm unaware of. Any
guesses?
