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:


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.
