ICL 2900 series mainframe. Look like EDS 60 drives as well. Not sure what is happening on the Oper screen. Doesn't look like George IIs/DME/VME operating system.

I thought I was the only person who actually recognised the systems. I started my life on the ICL 1900 series.

Wasn't even founded until the late 60's
even I didn't start using the brown ones with the 8" floppies until the 80's.
You may have been using the Odhner Arithmometer in 1900 mind you. Which had similar functionality. (As I recall)

And if so, was it any better than their IDMS offering?
(Which, in my humble opinion, was a pile of hierarchical pointer-based shite.)

IDMSX was/still is better than the bastard IBM version. And VME easier to develop on than IBM z/os systems I work on now...

...(was that a 'relational' jobbie?) but the one I worked with was evil incarnate. God help you if you needed to increase the size of a database: Certainly sir, just run this set of utilities to dump the whole thing off (as 'flat' files) and then reload / rebuild it all again - only takes forever, with no guarantee of success. Poor old ICL support staff even wanted to buy integrity checking tools that I'd written!

I'm old enough that I was bought it when it was new. It is my entire inspiration for my computing degree, career and spending years on b3ta*.
