I just found this on the web. It is from SHARE 79 from August 1992. Nice
explanation of JES2 and HASP.

HASP (Houston Automatic Spooling Priority) -
(Houston Automatic Spooling Program) -
First introduced: OS/360.
Optional. IBM for NASA. Approx 1967.
Effectively replaced many of the functions
of OS Readers, Writers and Initiators,
although those components still existed.
OS RDRs: Still needed for reading jobs on tape.
OS WTRs: Still needed for writing SYSOUT to tape.
OS Initiators: Still needed for initiating jobs.
Jobs were submitted by HASP to the OS Init.
Used compression when writing spooled output.
Also had RJE facility (Remote Job Entry)
and NJE facility (Network Job Entry).
Later renamed "Houston Automatic Spooling
Program".
Evolved into JES2.
ASP (Asymmetric Multiprocessing System) -
(Attached Support Processing) -
First introduced: OS/MVT.
Optional. Not for MFT.
Derivative of DCS (Direct Coupled Systems) for
IBM 7090/7040 computers (1962...), prior to S/360.
Written by the same IBM group which wrote DCS
(IBM Los Angeles, Westwood).
Precursor of JES3.
Effectively replaced many of the functions
of OS Readers, Writers and Initiators,
although those components still existed.
OS RDRs: Still needed for reading jobs on tape.
OS WTRs: Still needed for writing SYSOUT to tape.
OS Initiators: Still needed for initiating jobs.
Jobs were submitted by ASP to the OS Initiator.
Created a loosely-coupled, single-system
image via channel-to-channel communication
between computers, and a shared Spool.
Also had RJP facility (Remote Job Processing).
With RJP, jobs could be routed to other
remote systems for execution, and the SYSOUT could
be returned to the local system for printing.
Main processor: The Global processor.
Other local processors: Local processors.
Name changed to "Attached Support Processing"
at some point.
Evolved into JES3.
