This late 1970s Tektronix 4025 is a "smart" terminal computer because it is capable of editing files and temporarily storing data on its own RAM; I noticed that one of the S-100 boards had a 8088 CPU. It basically can't load or save information without the mainframe computer. It has a green monochrome screen built in and has composite video output. The computer connects to the mainframe via an old style DB-25 (25 pin) RS-232 serial cable.

This 1978 Tektronix 4052 is a graphic computer system designed mainly for graphic design because of its vector-based display. Before the days of the HD, the computer uses cassette tapes for permanent memory (notice the large slot on the right). It has Tektronix BASIC built-in the ROM. More information on the Tektronix 4052 system can be found in the articles section.

This is a Tektronix 4611 electrostatic printer from the late 70s, it uses one large scroll of paper and the toner was poured in the printer.

This is a Tektronix 4662 interactive digital plotter that cost $3,995 back in 1977. It uses a pen that is moved via precision stepper motors and fine steel cables, and it has an electrostatic pad that holds the paper down. The paper size could be set by moving the pen to a position and pressing down SET LOWER LEFT or SET UPPER RIGHT until you hear a beep once. Pressing down the CALL button until you hear a beep twice causes the printer to draw a self-test picture. The joystick allows the pen to be moved around wherever you wanted. This plotter communicates with a computer, especially the 4050-series graphics systems via a GPIB (General Purpose Interface Bus) connection. Inside the plotter is an elaborate embedded 6800 computer system that provides unique capabilities for the plotter such as built in character fonts in memory. The computer only has to send simple ASCII information to the plotter and off it goes.

This is one of the two 4907 eight-inch floppy disk drive units as part of option 31. The model 4907 refers to a single drive just as large as the dual drive, but with the remaining space reserved for the disk controller that communicates to the computer via a GPIB connection. Unfortunately I do not have the main single disk drive with the controller so this dual drive is useless. The numbers on the disk drives (0 and 1) indicates the device number that would be used for selection on the computer.

This is a late 1970s cassette tape drive manufactured by Tektronix for reading and storing data on tapes. The one pictured above is the one I have without the top cover. The whole thing was inact and in good shape until I brought it back home and discovered that the entire top shattered in smithereens.

This is the 4952 joystick that went with the 4050-series computer systems and cost $560 new back in the late seventies. A POINTER statement is used to activate the pointer on the computer, and the joystick would move it around. If any key was pressed, the POINTER statement would end, the X,Y values would be stored, and the key pressed would also be stored.
