When I worked in a corrugated factory we ran twin-ax to the IBM 36 that ran the accounting systems.

I did get shocked running it once. I was connecting two twin-ax cables with a barrel connector so I had one hand on each cable.

The cable in my left hand ran to a PC, and the shield should have been at ground. But the outlet for that PC was miswired, and the chassis was hot instead of ground. So I had one hand on a hot shield and the other on ground.. I got the old familiar tingle across the chest.

Hope that safety issue was corrected. I've also
gotten zapped by a hot white wire, on odd occasions.

Sadly, I did not live to tell about it.

The attractiveness was it was the first truly scalable system. The
smallest table top AS/400 ran the same OS as the biggest multi rack
system. Eventually you will still run out of power though and the
transition to an "enterprise" system is as hard as an Apple user
moving to Windows.

It may have been the first truly scalable IBM system, but Burroughs
had two scalable lines (B[234]x00 and B[567]x00) before system/38 was introduced.

I also think the AS/400 guys would bristle a little at the idea that
these were "micro computers" (in the Wilki) since the larger models
were way up in the midrange mainframe category with some very large
companies running their whole IT department on one. To get bigger in
the mainframe business, you would be in a water cooled system.

Thanks for the reply. On this page it is said to be a midrange computer
- that should smooth their hackles a bit.

It's what was used for networking computers before Thinnet coaxial
cable networks which came before UTP,"Un-shielded Twisted Pair" for
networking and finally Ethernet. I can't remember the UTP network
protocol before Ethernet. I have pulled a lot of Twinax cable out of
older offices when upgrading the network to Ethernet. There is a lot
of scrap value in the tons of abandoned cabling in office buildings. (

Thanks for the info. I hadn't heard of it being used with computer
networks.

In addition to Thinnet, there was also Thicknet, these were mainly used for
Token Ring networks, to the best of my knowledge.

I missed out on that era because I was in the Navy. We had computers,
but not much networking was going on. Think UYK-20 "Yuck Twenty"
Sperry/Univac. When I got out AOL on dial-up was all the rage.

I always test even if I installed the wiring myself. I literally trust no one but I've worked 4160 or 4,160 vac underground cabling and pad mounted mounted transformers. Never believe that the circuit is de-energized without testing it before you touch it or as I do, work on it as though it's hot anyway because it's good practice. With high voltage, when your hair stands on end, you're screwed. I've received many electric shocks over the years but I'm OK, um, I'm OK, I........Was I saying something? ^_^

The attractiveness was it was the first truly scalable system. The
smallest table top AS/400 ran the same OS as the biggest multi rack
system. Eventually you will still run out of power though and the
transition to an "enterprise" system is as hard as an Apple user
moving to Windows.

It may have been the first truly scalable IBM system, but Burroughs
had two scalable lines (B[234]x00 and B[567]x00) before system/38 was introduced.

The system 360/370 series was scalable too but the low end was not as
small as the smallest AS/400 adjusted for the technology at the time
and you migrated from DOS to OS/360. The touted advantage to AS/400
was the OS stayed the same and all applications still ran as you moved
up through the hardware upgrades.

We never had much penetration by Burroughs, Univac or the others in
the business community. The Navy had some big Univac contracts tho.
