Famously the computer with a roof – but I didn’t know about the calendar (conviniently next to what seems to be an uptime counter)! 
Great images!
DEC’s PDP-1 was very similar to the modified TX-0 that was donated to MIT. I don’t think DEC ever had anything like the TX-2.
I think, the TX-2 was just too complex and too expensive to be commercialized.
