<div><font style="background-color: transparent;">I believe the gray Chyron keyboards shown in the film are Chyron II keyboards. The III, IV, 4000, 4100, 4200, and RGU all had similar ugly orange and beige keyboards. There is nothing magical about the keyboards and they could have used Chyron ii keyboards with Chyron III frames. </font></div>
<div><font style="background-color: transparent;"></font> </div>
<div><font style="background-color: transparent;">The II keyboards were long and thin as shown, whereas the IIIs that I am familiar with are big and boxy. So there would have been some space advantage in using the gray keyboards building a truck. I think the keystroke coding boards were all the same, it was the interface to the frame that changed a little. The characters we see could be from Chyron IIIs. The II through 4200 (and RGU) all used the same kind of run length coding to describe the characters. Bit mapping presentations didn't come along until the Scribe. </font></div>

<div><font style="background-color: transparent;">The III was a somewhat dumbed down version of the II and the 4 series were repackaged versions of the II. The 4100 was similar to the 4000, but it could have an accessory called MGM (Multi Graphics Module, I believe), which was another box about the same size as the CG, which allowed still captures and animation and video import. The 4200 was a 4100 with MGM in the same box. </font></div>

<div><font style="background-color: transparent;">There was a chronic problem through several generations of Chyron keyboards with the internal 5 volt supply drifting low in voltage and needing to be tweaked back to 5 volts. You would get erratic keyboard performance or nothing from the keyboard until you set the voltage back up and then all was well. </font></div>
