    >> its an 11 of some sort not sure witch one

Ah, OK. That's either an -11/04 or -11/34 in the top left corner, with either
an RX01 or RX02 above it. (Not enought detail in the image to say.) The rest
of it seems to all be some sort of custom medical or other specialized

(The /04 and /34 are very similar - the only difference is which processor
card(s) is/are plugged in - you can convert most -11/04's [it depends on the
specific backplane in use] to -11/34's by pulling the M7263 KD11-D -11/04
processor card, and plugging in instead the M8265 & M8266 KD11-EA -11/34A
processor cards, which still seem to be relatively prevalent.)
