Cool many thanks.

FYI: it's a great start.  It just the Terminal Control System part, there was about 5 or 6 subsystems, IIRC.  That's a fairly early version (1974) also, since its Fortran-IV.   Later versions in the late 70's/early 80s were in MORTRAN, BTW.  I remember an internal argument of the folks in the terminal group about if Plot 10's GKS system should be done in C - but FORTRAN still rules the day so, MORTRAN was the compromise.

Mark's looking at plot got me thinking, does anyone know if any version of the Tektronix Plot 10 sources has survived?   I have googled around and found a few manuals, but never the (Fortran) code itself.

I have a copy, but I don't remember where I found it...
