[cctalk] ADDS Viewpoint keyboard & serial terminals

I have an ADDS Viewpoint serial terminal that has a bad keyboard. Does anyone have a compatible key board to spare? Also, I'm planning to have 2 different 4 user systems up and running at VCF Midwest and I only have 2 working serial terminals (VT220 & VT330+) does anyone (preferably in the Chicago area) have a terminal or two they are looking for a good home for on the super cheap?  I don't want to have to use 6 laptops if I can avoid it.
