I think the Cobol Compiler came from the company we contracted with to 
do languages for us @Microdata.  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.
