I had taken two credit hr intro to Fortran/Computers. At the end of
semester was hired to rewrite 1401 MPIO in 360 assembler for 360/30
(64kbyte memory and 2311s). Univ was getting 360/67 for tss/360
replacing 709/1401 (709 tape->tape, 1401 unit record frontend) and got
360/30 temporarily replacing 1401 pending arrival of 360/67.

The univ. shutdown the datacenter on weekends and I would have the place
dedicated. They gave a bunch of hardware and software manuals and I got
to design and implement my own monitor, device drivers, interrupt
handlers, storage management, error recovery, etc ... and within a few
weeks I had a 2000 card assembler program. I didn't know about rep
cards, so learned to read TXT deck cards, duplicate cards, and
multi-punch hex patches.

Univ. 360/67 arrived within year of taking intro class and I was hired
fulltime responsible for OS/360 (768kbte memory and 2314s; TSS/360 not
coming to production, so ran as 360/65). 709 did student fortran in less
than second. 360/67 (as 360/65) os/360 (MFT9.5) took over a minute, I
install HASP cutting time in half. MFT11, I start redoing SYSGEN STAGE2
to carefully place datasets and PDS members to optimize arm seek and
(PDS directory) multi-track search, cutting another 2/3rds to
12.9secs. OS/360 never got better than 709 until I install Univ Waterloo
WATFOR; as 360/65, WATFOR clocked at 20,000 statements/min (333
statements/sec), student fortran tended to run 30-60 statements.

Then IBM CSC came out to install (virtual machine, precursor to vm370)
CP/67 (3rd after CSC itself and MIT Lincoln Labs) and I mostly get to
play with it during my weekend 48hr window. I then spend a few months
rewriting pathlengths for running OS/360 in virtual machine. Source was
in OS/360 files which had to be modified, assembled, mark txt deck and
merge it into a tray of txt decks (that was CP67 executable). BPS loader
IPL the tray of TXT decks which then writes core image to disk, for
ipl'ing the system.

Bare machine test ran 322secs ... initially 856secs (CP67 CPU
534secs). After a few months I had CP67 CPU down from 534secs to
113secs. I then start rewriting the dispatcher/scheduler , (dynamic
adaptive resource manager/default fair share scheduling policy), paging,
adding ordered seek queuing (from FIFO) and mutli-page transfer channel
programs (from FIFO and optimized for transfers/revolution, getting 2301
paging drum from 70-80 4k transfers/sec to channel transfer peak of
270). Six months after univ initial CP/67 install, CSC was giving one
week class in LA. I arrive on Sunday afternoon and asked to teach the
class, it turns out that the people that were going to teach it had
resigned the Friday before to join one of the 60s CSC CP67 online
commercial spin-offs (one offered Mathematica RAMIS, when RAMIS was also
offered to TYMSHARE, they did Nomad, then some former Mathematica do
FOCUS at Information Builders)

Before I graduate, I'm hired fulltime into small group in Boeing CFO
office to help with formation of Boeing Computer Services (consolidate
all dataprocessing into independent business unit). I think Renton,
largest datacenter in the world, 360/65s arriving faster than they could
be installed, boxes constantly staged in hallways around machine room
(did have lone 360/75, when doing classified work; black rope around
area, guards at corners, heavy black felt covering console lights and
visible 1403 printer areas). Lots of politics between Renton director
and CFO, who only had a 360/30 up at Boeing Field for payroll, although
they enlarge the room to install 360/67 for me to play with when I
wasn't doing other stuff. I had mid-level management badge so could park
in lots closer to the bldgs.

747-3 was flying skies of Seattle getting FAA flt certification. Tours
of mock-up of 747 cabin just south of Boeing field would claim 747s
carried so many passengers, they would never be serviced with fewer than
four jetways. Both Boeing and IBM told stories about 360 announcement
day, Boeing submitted an order making the IBM marketing rep, highest
paid IBM employee that year. Sales were still straight commission; IBM
shifts to quota the following year.

At Boeing I modified CP67 to support portions as pageable
kernel. Problem was adding more CSECTs (dividing pageable kernel into 4k
segments). Problem was I ran into BPS loader had 255 csect limit ...
and I was constantly doing hacks to keep the pageable kernel within 255
limit.

When I graduated, I joined CSC (instead of staying with Boeing CFO) and
one of my hobbies was enhanced production operating systems for internal
datacenters (one of the first was the branch office online
sales&marketing support HONE was one of the 1st & long time customers).

CSC had several card drawer cabinets up on the 9th flr attic ... and
prowling through them found source for BPS loader, and modified it to
double the maximem csects ... greatly simplifying pageable kernel
(wasn't released to customers, but picked up for VM370 follow-on).

Co-worker was responsible for CP67-based scientific centers wide-area
network. He had three "PUNCH" statements at front of the network
assembler source ... that punched hex for a 3card loader. This morphs
into the internal corporate network (larger than arpanet/internet from
the beginning until sometime mid/late 80s, about the time it was forced
to convert to SNA/VTAM).

Some of the MIT CTSS/7094 had gone to the 5th flr to do MULTICS and
others went to the scientific center on the 4th flr and done virtual
machines, networking, invented GML 1969 (morphs into SGML a decade
later, after another decade morphs into HTML at CERN), etc

Looking at what they were doing for MULTICS on the 5th flr, I created
page-mapped filesystem for CP67/CMS ... want to be able to just map
virtual memory addresses to pages on disk (w/o having to preload them
for the loader could modify the addresses) and support location
independent R/O shared (executable) files ... which I later migrate to
VM370/CMS.

For VM370R3, there is a very small subset released as DCSS, extending
shared segment to more than kernel supported with more than just the IPL
command.
