I forgot to mention that in the load of stuff i picked up yesterday were several Terminal Units. 1 ea IRL FSK-500 1 ea Hal ST-6 1 ea Dovetron MPC-1000 and one identified as being from Midnight Engineering back in Illinois. Know nothing more about these. I've not even plugged them in to see if they light up yet. I certainly don't need them with all that i have. Larry W0OGH
