These photos were the last I've ever taken using Kodak Tri-X film with my Rollieflex F 2.8. I was a field engineer for Link assigned to the installation and de-bugging team for this piece of equipment at the Manned Space Center south of Houston. The job required 3 months of of 12 hour days, seven days a week, to complete.
Love looking at old hardware, kind of fascinating how far we've evolved technologically in the last 50 years. My dad was a Computer engineer and programmer from the early 60's through the 70's and I used to print & feed the punch cards.
