How Old is Your Total Station?

I have a 1986 GTS-3B. It still works, but getting long in the tooth, so it's been retired to a warm spot by the fire.

I have about a 1986-7 gts 3-c.
My my, that was a dream tool.

Leica TCR305 and a TCR 307 from turn of the century.. Both have unreadable displays that are unavailable from Leica. Both occaisionally jump angles, usually in multiples of 35 minutes. One has a frame that's all corroded and blistering. I admit, they have been ridden hard and put away wet sometimes.
Also a 1105 bought used here that's away, hopefully for repairs.
