Tektronix keyboards

The ones with the DIN style connector were used on the 4105 terminals and the ones with the RJ45 type were used on the 4205 terminals. (I have terminals of both types and keyboards of both types.) <http://terminals.classiccmp.org/wiki/index.php/Tektronix_4105> <http://terminals.classiccmp.org/wiki/index.php/Tektronix_4205> The big button on those keyboards is a "joydisk" that can do the work of a mouse when you don't have a mouse. My XD88 workstation didn't come with a keyboard and I haven't attempted any powerup of it yet. Looking at the catalog picture from 1990, there is definitely a joydisk on the keyboard. It is on the right below a cluster of 6 keys and to the left of the numeric keypad cluster. See PDF pg. 464 here: <http://manx.classiccmp.org/collections/legalize/tektronix/catalog/Tektronix_Catalog_1990.pdf> However, on the very NEXT page, they show an XD88 workstation with a more traditional keyboard and just a 4 key cursor arrow cluster. On both the 4105 and 4205 keyboards, there is a 9-pin serial port for attaching a mouse. So you could either use a real mouse attached to the keyboard, or the joydisk if you didn't have a mouse. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
