Pointer about NASA computer and launch facilities http://www-pao.ksc.nasa.gov/kscpao/facilities/lps.htm http://www.hq.nasa.gov/office/pao/History/computers/Ch4-6.html http://spaceflight.nasa.gov/shuttle/archives/sts-70/shutref/sts-av.html#sts- dps-gpc The computers are called the GPC's. I seem to remember that each shuttle carries a phone book sized volume of the known software bugs/limitations. Many of the problems would require software rewrite which would require recertification so they are left alone. One know bug was/is that the input consoles share a common keyboard buffer, if two persons type simultaneously then you end up with a mixture. There is an ACM article in September 1984 that covers the GPC computers. Mike mmcfadden(a)cmh.edu
