Flashback time for me! In the 90s I worked contract at IBM Boulder, “owner” of 9 AS/400 systems for a remote customer. All were 800 & 900 series machines, one had 11 8-foot tall cabinets. Hold several IBM/HP/Linux certs for many AS/400, RS6000 and AIX/Un*x/Linux flavors and have to say of all the different systems I’ve used that AS/400 DB2 is the most flexible and best performing due to its interactive and batch systems. I miss working that platform!
Hi Q1745, you'r right, same for me, but coming from MVS, i still think this is the best operating system, and i can tell you because i did a lot fo performance stuff on it, it can run massive volumes of transactions. its so reliable, the only time I had to force a shutdown by the power was on version 1.0 unpatched version (AS400). i have never "lost" any system after that, never.
Make sure you clone that hard drive at some point. It is a good idea to run these machines for a while to let the bearings warm up and re-lubricate bearings in the drives. Hard drives have greatly improved since the late 1990's. These were great rock solid computers of the world before microslop took over. Nothing bad to say about AS/400!
@@MichaelAStanhope thats it, the powering time is more depending about the number of devices (disks but also line controllers etc) around it than the speed of the processors.
I have a 30 year career on the platform. Hard to find work on the AS400 now and will be retiring in a couple years. Would like to get my hands on a system for my own use.
12 minutes to boot? By that time had a LONG time to WARM UP. I would call the cold boot on that machine a WARM BOOT! I'm glad we can buy a Raspberry Pi 5 for less than $100 these days!
in a previous job our AS/400 took about 1-2hrs just to get a login console on the terminal that was directly connected to it. was not a fun night when i knocked out the UPS it was attached too.
I'm fascinated by that monitor. I assume that it's due to a refresh rate / shutter speed mismatch, but why are only some portions of the text flickering and not others? Is this a conventional CRT?
I think there's more to it. The red text isn't red. It's actually alternating green and then red. The grey text is doing the same. Looks like they're doing the color bits on entirely different refreshes. @@StevesTechShed
It appears that the red text is overlaid on the green on every other frame, and the grey is overlaid top half/bottom half on alternating frames.@@StevesTechShed

Go work for Terminix, Qualfon, Prime Pharmaceutical. They still use these machines.

Good commercial machines. I worked with them extensively in the 1990s and early 2000s.
I work a customer service job that still uses an AS/400 platform for one of our critical systems. If it isn't broken, don't replace it!

12 minutes, im jealous. It takes over 20 mins for our IBM Power7 to boot when it looses power!
My Power9 running on a Storwize NVMe flash takes 1.5min to boot. :)
@@TronBons we are still running 15k SAS drives on ours. Thankfully we only have to bring it back up after a major power outage!
@@MichaelAStanhope thats it, the powering time is more depending about the number of devices (disks but also line controllers etc) around it than the speed of the processors.
My Power7 with 1 CPU and running from a single 137GB 15K SAS drive takes 9.5 minutes from LPAR activation to IPL V7R2.

We still run them at my work. The insurance industry seems to still love them!
@ joe......You know about the cripple SOFTWARE? Hope that You can find a top of the line system.
Joe, where are you located? I may have a project for you.
It sounds like a helicopter taking off! Love the retro monitor
it brings back the memory of the good old days.. I am not going well along with the newer technology ... lol ..
Cool Im trying to find a AS/400 to play around with I used one at an old job in a Warehouse for a while

this is waaaaay older.... 20 years ago, we have like AMD K6 or something....
No, this is definitely from around the year 2000 (check IBM eServer iSeries on Wikipedia)
I want to reinstall my as/400 . Have the licensed codes and the dvd's but i forgot how after 20 years....
I have one im trying to get to boot!! This is awesome!
👍👍

Yeah it's a standard CRT. It must just be the camera's shutter speed vs the refresh rate!

@@JamieVegas I missed your comments - yes this is fascinating how the refresh is working!
We are doomed if the world have to reboot 😂
