The NAS Equipment

This new equipment was added in 9/1981:
National Advanced System AS/9000N with 12MBytes of main memory
6 STC 9 track tape drives of density 1600/6250 bpi
4 STC disk drives for a total of 5 GBytes
1 1000 cpm reader
1 1800 lpm printer
OS: IBM VM/SP & MVS 3.8

This machine was acquired to be the primary academic machine. Academic users on the Honeywell system were migrated to this system.

I installed the first VM/SP system on this hardware.

I also developed some privileged mode software using C to allow privileged users (system programmers) to easily change from one userid to another without having to log out and then back in. This was very similar to the "muid" command under "wizz" on the Honeywell system. Walt Barnes, a University of Houston employee, developed wizz at the University of Kansas before coming to UH.

I also developed a system shell (sort of like the unix shell on U*IX) for CMS on VM that mapped the CMS file syntax to a DOS style syntax i. e. "file type disk" into "disk:file.type".

This software was installed in 9/1983:
OS: VM/SP2 release 2.1

In January, 1984, BITNET came to the University of Houston. I developed a "Query" exec to get the identity of a remote node and a "Trace Route" exec to trace the path to a remote node. The NAS9000n's BITNET node name was named UHUPVM1 for University of Houston University Park Virtual Machine #1.

OS: MVS was removed in 5/31/1984

In May of 1986, VM/SP Release 4 was installed on the NAS9000

In the fall of 1987 VM/SP 4.1 was installed on the NAS9000n

In February of 1988 the following hardware was added to UHUPVM1:: 4 7380E disk drives with 4 drives each for a total of 20 GB

In the fall of 1988 VM/SP 4.2 HPO was installed on the NAS9000n

In the fall of 1989 VM/SP 6.0 HPO was installed on the NAS9000n

In the fall of 1991, the NAS9000 was replaced with:: IBM ES/9000 model 190 with 64MBytes of main memory; 6 STC 9 track tape drives of density 1600/6250 bpi; 4 STC disk drives for a total of 5 GBytes; 1 1000 cpm reader; 1 1800 lpm printer; OS: IBM VM/HPO -CMS
