9-Track 1/2" Tape Drive Recommendations?

There was an outfit here in Orange County, Ca that was a den of oddballs 
who actually like to write compilers and were good at that was called 
CSPI.  In the 78-79 timeframe, Microdata bought a compiler for Cobol and 
Fortran from them with a really big check and helped them along the path 
of becoming a viable company.

They then had a fellow as a contracter, Mas Okano, who also contracted 
for Olivetti for a long time and for CSPI maintain it as the Express 
system was sold to Olivetti and transferring into one of their main 
systems.  I think Mas was there till the mid 90s, but CSPI went out of 
the picture.

Anyway, one of the things that Express was competing with were DEC 
systems and they benchmarked both the Fortran and the Cobol and outran 
DEC.  Express was still a miserable failure for them, and they of course 
only made the one system design and never enhanced it.  Someone with 
better knowledge about DEC can guess the 11 and OS.

Anyway another thing they had to do was pass this test, and I suspect it 
is the one that Chuck refers to.

CSPI was bought up by or morphed into one of the outfits which sold 
Cobol compilers for the PC, but I don't know which one.  If one looks on 
bitsavers at the front of the Microdata Express Cobol internal spec, it 
was prepared by CSPI, California Software Products, Inc.

Unfortunatly, it is really just the compiler spec, and doesn't have what 
I know were in other documents, the requirements for the spec.

It is a good writeup of the internals of a compiler if anyone is 
interested.  I believe both Fortran and Cobol used the technique of 
compiling to the intermediate target MOM then on to machine code, 
enabling them to sell the compiler to other vendors.  Microdata paid for 
the first one though in 79

I also think they had the tests and ran them for Microdata and submitted 
the results as the tests were very involved.
