(I guess I stay up late looking at my own screengrabs)
The Japanese are no angels ether. I guess since digital PBX systems were derivatives of the design of mainframes, the consoles that used to manage mainframes, were not based on CRT in the beginning. Heck even the first PC – the Altair, was filled of complicated LEDs and switches.
This console most likely is used for the NEAX PBX system (the equivalent to the M1, the G3, or SX systems.)
In the late 90s, early 2000s, they too got their act together, and had a sleek console with the user in mind.
Again not my pictures, was taken from an eBay listing.
