It works just fine... I configured my H11 box with an 11/53+ (KDJ11-D)
processor.

I suggest you get an MXV11-B board. This has some memory, two serial
lines and the boot code all on board. Then you'll need some sort of
disk interface, like RQDX3 (and a couple of disks). You'll need to
find a leprechaun box (external desk-top mounting box for RD series
disks, the kind which go with the RQDX3).
