Is it a lost cause?
closer to the sigma was series/1. the series/1 peachtree processor
was significant more capable than what was selected for the 37x5
communication controllers. early 70s, the science center ...
some past posts
strongly lobbied the communication group to choose the preachtree
processor for the 3705 (rather than the processor they were designing)
... and lost.
the folklore is that the official series/1 RPS system had been done by
some former kingston os/360 MFT people that moved to boca and tried to
reimplement os/360 MFT ... which wasn't good match for the series/1. The
folklore for the alternative EDX system was originally done by some
summer co-op students at IBM San Jose Research physics lab.
Late 70s, early 80s, one of the baby bells did a 37x5/NCP emulator on
series/1 .... the encapsulated SNA RUs in real network, emulated SNA
sessions as "cross domain" (i.e. VTAM emulation with
no-single-point-of-failue session management out in distributed
series/1). Mid-80s, I got sucked into turning it into type-1 product.
We tried to put in brickwalls anticipating the corporate dirty tricks
that the communication group was well known for. What the communication
group then did can only be described as truth is stranger than fiction.
Old post with part of presentation that I gave in Raleigh at SNA
architecture review board meeting
part of presentation by one of the original implementors at
'86 common user group meeting
continue the lost cause theme ... periodically repeated, in the late
80s, a senior disk engineer got a talk scheduled at the world-wide,
internal-only, annual, communication group conference, supposedly on
3174 performance ... but opened the talk with the statement that the
communication group was going to be responsible for the demise of the
disk division. The issue was that the communication group had corporate
strategic "ownership" of everything that crossed datacenter walls and
they were strongly fighting off client/server and distributed computing
trying to preserve their (emulated) dumb termina paradigm and install
base. The disk division was seeing data fleeing the datacenter to more
distributed computing platforms with drop in disk sales. The disk
division had come up with a number of solutions to address the problem,
but they were constantly vetoed by the disk division. some past posts
a few short years later, the company goes into the red and was being
reorged into the 13 "baby blues" ... in preparation for breaking up the
