  Totally feeling the engineer who couldn't accept this machine being scrapped and instead hauled it into his garage 😅👍

  I worked for IBM for over 47 years. I worked on almost all main frame processors from ok 1400’s, 360’s, 370’s, 43xx, 30xx. It was a great career. Even AS400. And all peripherals.

  I was a CE worked on 370 158 and 303x along with all the IO. Joined 1978 and worked on most IBM 360 and 1403

  I remember I had one of the manuals for this computer as a kid ... I treasured it so much even though I couldn't understand a single thing..... later when my dad bought mean IBM 5160, I kept the manual on the shelf next to the manuals for the XT.

  My fist job out of high school was an operator of 370 mod 158 and a 360 mod 50 for a local bank. Thanks for sharing the video.

  This was the last machine I ran as an operator that made you feel like you were actually doing something! I used to love doing IPLs just because we could turn knobs and push buttons! I changed jobs and the next datacenter had a 4331 with the 'Maytag' flat tape drives! I went fulltime into systems programming and we went through the whole 4300 family, through the 9672s and into the Zseries. They are still running the Z12 we had when I retired.

  This brings back a lot of memories.  I might have actually worked on this machine.  I was the Quality Engineer for the 370/148 and the 370/138 built on the same line in Endicott NY.  Later went on  to design test equipment for the 4300 series, then the 9370.  Remember a few details about them. The 138 implemented the 370 instruction set using what was called vertical microcode.  It was similar to what an assembly code.  The 148 used horizontal microcode.  Each clock cycle it would apply a very long bit string to gates throughout the machine, causing different sections of logic to execute based on whether a specific bit in the microcode was on or off.   Really hard to write.

  Great video! My father started with a System 360.. S/370... and new models.. I had my first contact with a computer when I was 12 years. I built some EXEC, EXEC2, Rexx, Assembler....  Since that moment, I work with mainframes. I never forget of these old models... :)

  I had to chuckle at a flashback I had at your comment about the ubiquitous Emergency Pull knob. The second computer I ever worked on was a S360/30 at my small community college. The operator who trained me always had it unscrewed and just resting on top of the machine. I was told, in no uncertain terms, to never, ever, EVER pull that knob unless I saw flames over 3 feet high coming from the top of the unit. Fortunately, that day never came.  Enjoyed the video.

  good to see an old 370. In the 1980s and 1990&apos;s I was a partner in leasing co and we had 40 360&apos;s and 370&apos;s on lease &nbsp;in the nyc area.<br>We would custom paint the machine to customers order. IBM would do the same. Usually just cans of ibm spray paint. red, white, yellow, blue.<br>the front panel was always black.

  Very cool. I&apos;ve decided to return to the mainframe and then finish my career in a few years. I&apos;ve spent the past few months getting back up to speed on OS/MVS on Hercules TK4. Now transitioning over to z/OS and zDTE.

  The one thing about our 370/145 was the incredible noise the MG made. I always thought we had one was so that we could run a machine destined for US voltage and frequency from UK&apos;s. It seems that this wasn&apos;t the case.<br><br>The 4341 we had (I was working for a different company by then) was nicknamed the freezer because that was exactly what it looked like - a large chest freezer.
