Regarding Nasa's Tidbinbilla Tracking station, someone suggested to me they might have had MODCOMPs https://en.wikipedia.org/wiki/MODCOMP Cheers, uncle rubl =========== From: Wesley Parish <wobblygong(a)gmail.com> To: Computer Old Farts Followers <coff(a)tuhs.org> Cc: Bcc: Date: Tue, 4 Feb 2020 14:25:25 +1300 Subject: Re: [COFF] How much Fortran? My thoughts exactly. I was once lucky enough to visit the NASA's Tidbinbilla Tracking Station in the ACT just a few miles out of Canberra c. 1976 or 77, and they had some sizeable minicomputers in their computer room. (How many I don't know.) I imagine they would've been used to record the transmissions on tape and do some preliminary processing, before sending the tapes to NASA HQ in the States for storage and further analysis. I think what NASA did with their early probes would've made Real Programmers (TM) sit up and gasp. :) Does anyone on this list know anyone who worked at a tracking station during the 60s and 70s? They might be able to help fill in the details. Wesley Parish
