At CERN my experiment, ALEPH, made heavy use of VAXen.
We used 730s and 780s for data acquisition at beam lines.
Down in the experimental cavern the DAQ was FASTBUS but there were VAXen down there too.
For analysis as I remember VAXen clustered together really easily, with a maximum limit of 128 machines. So we had at least two clusters in the CERN server hall.
In the latter days there were Alpha servers in the mix too.
I was like a dog with two tails when I got my very own FALCO terminal. This did amber screen DEC VT220 emulation, but then with a hotkey did Tektronix emulation. So you could develop colour graphics programs and see the results on the same terminal!
I was rather an expert at GKS if there is any call for those skills!
Do you think NASA will give me a job then?
