Devon, 1973 Siemens 4004*APL
In 1972/73 I lead a team from I.P. Sharp Associates working in Heidelberg Germany to develop an APL system for Siemens. The Siemens hardware was very similar to the IBM 360 (same base instruction set) but had extensions that faciliated timesharing and virtural memory. The operating system was BSV 4004 and was quite different from the IBM offerings at the time. The Siemens machine was very closely related to the RCA Spectra series. The Siemens 4004*APL system was discussed in my paper at the 1973 APL conference in Copenhagen. Siemens APL was relatively successful in Germany and over the years grew to about 50 mainframe installations. /Eric ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
