some of you will perhaps remember me being stuck
with a problem
regarding a Fujitsu FANUC "mate TG" CNC controller (rebadged as
"Siemens Sinumerik"), of which I have the main unit but not the
monitor. Thanks to a very nice guy living nearby, I was provided with
some new information about the interface, which is rather uncommon in
itself. I had already guessed that there is a significant amount of
smarts in the monitor; the newly acquired documentation confirms
this.
The silicon brain (CRT controller) of the thing
is called LSI
HD46505.
I beleive the HD46505 is basically a clone of the Motorola 6845 CRTC,
so there's not a lot of information there.
