But it's half-ASP.

OS/360 and OS/VS2 had native spooling services. The ASP and HASP services
were allegedly more efficient.

RJE was a native OS/360 facility. Both ASP and HASP did their own remote
batch processing without using any of the RJE code. Contast this to input,
where both ASP and HASP had to use the Reader Interpreter as a subroutine.

NJE came later.

I don't believe that the name was ever "Attached Support Processing";
AFAIK it started out as "Attached Support Processor" and later changed to
Asymmetric whatever.

I believe that ASP eventually supported MFT II, which shared a lot of
Scheduler code with OS/360 MVT.

I believe that APS had DSP's for reading and writing tape. The OS/360 and
SVS R/I was needed for reading any job, not just from tape.
>Main processor: The Global processor.
Other way around; there was a single support processor and multiple main
processors.
