IBM 3090 Training

Between 2001 and 2004, I had an office in the home of the mainframes, IBM Poughkeepsie, in Building 705. As a Brit’, it wasn’t my natural home, also, I wasn’t a developer or a designer, as a software architect focusing in software and application architectures, it never felt like home.

IBM Library number ZZ25-6897.

One day, on my way to lunch at the in-house cafeteria, I walked by a room whose door was always closed. There was a buzz of people coming from it, and the door was open. A sign outside said “Library closing, Take anything you can use!”

I have some great books, a few of which I plan to scan and donate the output to either the Computer History Museum, or to the Internet Archive.

One of the more fun things I grabbed were a few IBM training laserdiscs. I had no idea what I’d do with them, I had never owned a laserdisc player. I just thought they’d look good sitting on my bookshelf. Especially since they are the same physical size as vinyl albums.

Now 16-years on, I’ve spent the last 4-years digitising my entire vinyl collection, in total some 2,700 albums. One of my main focus areas has been the music of Jazz producer, Creed Taylor. One of the side effects from that is I’ve created a new website, ctproduced.com – In record collecting circles, I’m apparently a completionist. I try to buy everything.

And so it was I started acquiring laserdiscs by Creed Taylor. It took a while, and I’m still missing Blues At Bradleys by Charles Fambrough. While I’ve not got around to writing about them in any detail, you can find them at the bottom of the entry here.

What I had left were the IBM laserdiscs. On monday I popped the first laserdisc in, it was for the IBM 3090 Processor complex. It was a fascinating throwback for me. I’d worked with IBM Kingston on a number of firmware and software availability issues, both as a customer, and later as an IBM Senior Software Engineer.

I hope your find the video fascinating. The IBM 3090 Processor was, to the best of my knowledge, the last of the real “mainframes”. Sure we still have IBM processor architecture machines that are compatible with the 3090 and earlier architectures. However, the new systems, more powerful, more efficient, are typically a single frame system. Sure, a parallel sysplex can support multiple mainframes, it doesn’t require them. Enjoy!
