They were called CSPI, something like California Software Products, Inc., in Orange County, CA. We payed them about 40,000 apiece for a product called Microdata Express to write support compilers for Cobol and Fortran.? Intended to be competitive with the Dec PDP11, and actually was faster.? We wrote our own OS, I was an architect with another guy of a lot of the OS. Anyway they threw in a microcode compiler / assembler for the Microdata 3200, and also did a rework of the EPL system language tool which the system was coded in.? It originally was derived from McKeeman's XPL project. He and his group were at UCLA, and contracted on the OS. (digressing a bit). I heard that the 370 emulator company merged with, or was bought up by the compiler operation, and the result became MicroFocus.? The first compiler I think ran on the PC or the AT, and with the addition of the 370 emulator, it became a tool to migrate things off the mainframe, or allow support of distributed parts of application systems on PCs.? Or that was what they wanted it to be. thanks Jim
