Most of the period stuff that was using Tek 401x terminals was To each other on the screen, because the deflection distance is This takes more time than if you ask it to draw vectors that are close Unconnected vectors that are distant from each other on the screen, Post by plan to fine tune the appearance of the bright spot, the speed ofĪre you simulating the deflection speed? The deflection circuits in Shows it playing back the standard 'DISSPLA' demo file. Guessing they are the same as the 401x because a video of the 4002 Where did you find documentation of the 4002 control codes? I'm I couldn't findĪ date on the ARDS terminal, but it's entirely possible that TektronixĬommercialized one of the several adaptions of its storage tube as The 4002 first appeared in the 1969 Tektronix catalog. Seems Multics had some support too not surprising given the connection History of Project MAC, CDI, and Tektronix and get this sorted out. 'Someone ought to' (code word for 'it'll never happen') dig into the Seems to be an obvious connection both in appearance and control codes. It really does!
