[Unix-jun72] T4002A

[Tim Newsham]

An early section of the jun72 document has some code for
"modifications to UNIX to accomodate the T4002A graphic console."
Is anyone familiar with this?  If we could emulate this device
easily, it might be fun to enter this patch as an optional patch
to the system.

I worked with a successor device the Tektronix 4010. It's a storage  
scope that doubles as a terminal. It ought to be easy enough to  
emulate the alphanumeric part of this with a terminal but the  
graphical capabilities would be a challenge -- especially if  
portability was an issue. But if it wasn't challenging it wouldn't be  
interesting or any fun....

just my $.02

xterm can emulate a 4014. I don't knwo how much the protocol changed
over the years, but if it was mostnly similar then that code from
xterm could serve as a good starting point.

IIRC, the good news here is that the Tektronix terminal was just a
serial attached device that did its drawing with escape sequences that
are well documented/understood.  Many early X terminal emulators has a
tektronix mode, for example.  That makes emulation a little easier.

I hope that the 4002A is one of these beasts.  I recall seeing it on
an emulation list for a tektronix emulator I worked with in the early
1990's, but it has been long enough that the neurons may have
decayed...
