It turns out one doesn't need the fancy cab-kit to connect up to an 11/23+'s
console. The headers on the card are completely compatible with standard
DLV11-J connectors, and a DLV11-J cable can be used to connect up to an
11/23+ card. (One has to select the desired baud rate with the DIP switches
on the card, of course.) I have verified this by trying it, and it worked.
The cabkits merely allow one to select the baud rate at the console connector
(via a clock generator on the cabkit, and the 'external clock' input on the
serial interface). This implies that one should be able to plug a cabkit into
an appropriately configured DLV11-J (external serial clock select), and
select the baud rate via the switch on the cabkit. I haven't tried that,
though.
If anyone is looking for the real cabkit for the M8189 PDP-11/23+ JT
Computer currently has some listed on eBay for $45. There were 5
listed, 2 sold last week:

CK-KDF11-BA M8189 CABKIT INCLUDES PANEL AND CABLES
I finally got around to buying a CK-KDJ11-D cabkit for the M7554
KDJ11-D directly from their website (
www.jtcomputer.com ) a week ago.
I've had good results buying a few things from them.
