In Germany (maybe also Austria?), that font is probably best known from the logo of major computer magazine/site CHIP (https://www.chip.de/). Although, for some unfathomable reason, the C in the "dead test font" doesn't have the characteristic "thickening" in the lower vertical part, although the G has it...
Good ol' It's A Computer (tm) font. A good while back I've been using Westminster in every piece of UI I wrote for myself. Maybe I should start doing that again.
Nice exploration, bit of quirky fun.
