I didn't find programmer manual for tektronix 4051 or 4052 to download but i did find in this forum alink to download for tektronix 4111 i've. With this terminal, that i bought without host which is'nt needed, there is some to sell on ebay, which power on, display color and have a console line interface that can be use to display line without host. There is a bunch of eproms in back of it and in manual computer display terminal they say that these eproms can be change for an upgrade (roms remplacement procedure Appendix A). So i suppose that the program manual talk about the internals of these machine, and how to change these eproms rather than for the connection as graphic terminal to an atari, or to emulate an atari with a tektronix terminal connected to a host. But it can be of interrest for the communication processe (? to speed it). In the manual for tektronix cx4111, that have many pages to scan, they say that it can communicate either with dma 737K baud, coax host connection (IBM) or rs232 38.4K Baud full duplex. I didn't find the dma port back the cx4111, perhaps is it inside. I've these documents, that i will scan: TEK operators manual revised JUL 1986 "4111 computer display terminal" TEK users information supplement cx4111 computer display terminal" TEK reference guide "4110/4120 series with 3D" TEK users manual "4696 color graphics printer" and TEK users hanbook "an introduction to computer color graphics" Which best scan format to scan these books ? Can an eprom dump will help you ? Perhaps you will find interesting things for your tektronix 4052 within that docs to get your atari terminal console game vintage TUBE up and running. The manual say 4096 colors, 16 colors at a time, 1024 x 768 pixels on 19 inch color display screen , 3.25 ms, 60hz non interlaced, programmables keys. I've to dig in to find 4096x4096 mode. Thanks very nice project, all infos, links you give.

Well that's pretty cool. Although, I'll bet if you had an actual Tek terminal and told it to draw two parallel lines separated by one "pixel" of space (1/4096th of the screen) you wouldn't actually be able to discern the two lines anyway on account of beam diffusion. I could very well be wrong, though. Anybody out there with a Tek terminal who wants to take a macro photo of that for us? The photos show a vintage tektronix CX4111 with keyboard, phaser printer and documentation. It isn't broke, power on, and draw image. So i will fix it, need bisync protocol card, xterm. There is other atari 1024 somewhere, i will look if it have a vector graphic screen. I meet this forum looking on NASA web server about MARSS software and graphics made by tektronix terminals. I'm not sure that current graphics cards obsolete this technology. Thank to this forum to provide all these infos.
