4 popup team members behind the PopUp stand at GSEThe UK PopUp team (or “PopStars” as we call ourselves) attended the GSE conference at Whittlebury Park from 30th Oct – 2nd Nov 2023. It was a very well-attended event, brimming with mainframe enthusiasts, and copious deep discussions on all aspects of mainframe.


Thank you to the organisers, it was well run and enjoyed by all.

What else we got up to

The team were joined by a brand new addition to the PopUp team – ‘mini PopStars’ in the form of lego minifigures.

The ‘mini PopStars’ got to meet their idol – the human-sized lego z16.
