KXT-11 was the t-11 cpu, duart (2 dl lines), PIOs ram and prom on one dual 
width card.  It was designed as a bus master.

KXT-11+ was also T-11, quad width with peripherals on board but could work 
as both bus master and bus slave.

KXJ-11 was the later versionusing the J-11 cpu.

The were intended to replace lsi-11/03 and /2 cpus for embedded operation.
They with proper memory would run Rt-11 and could be used for a self 
development system.  At one time I had one in a BA11-va (showbox) with
a RXV21 and MXV11 and it was a very good 32k RT-11 system.

I also reassembled a MDS-11A a Vt100 with a PDP-11 qbus inside as a 
desktop development system for PDP-11.
