Intel MDS units

I just picked up a couple of Intel MDS units last week and now I'm not quite sure what to do with them. I have an MDS-225 with an MDS-230 keyboard. The unit is dated 7/80. I also have an MDS-120 with an MDS-120 keyboard. This unit also includes an ICE 86A BB Intellec module which is attached. I have no documentation to go with these items and as far as I can tell, they were taken out of operation many years ago and just stored. I have no way of verifying if they are working or not. Is there a market for these units? They are pretty heavy. I can strip them myself if need be, but if there is someone who can put these to good use, I'd rather see them go there. Any ideas, thoughts will be appreciated. Bill Machacek Colo. Springs, CO
