They were rather limited in computing terms, but it was easy to add custom i/o to them. There were lots of application packages, so I believe that many were used for specialist tasks. I bet both the Ship Research and the Gas Board used them with CSMP for solving differential equations. There was ECAP a circuit modelling program. It really was sold as a departmental or personal computer. > > Does that number also include the 1800? > I don't think so. According to http://ethw.org/IBM_1800 about 2,000 IBM 1800's were sold.. > --Chuck Dave
