About 5 years ago I saved these pics off eBay of what looked to me like an
Eastern Bloc PDP-11/15 console.
As I have a (rebadged) 11/15, I thought they were interesting.
These aren't my photos, I don't own them, saved for educational purposes only.

Just followed the sale of the 11/05 on eBay (#175655196586) that ended a

price.
