Electronic Tool Co. ETC-1000

Source: Electronic Tool Co., 1976

The ETC-1000 was used a design typical of early 1970s microcomputers. The main components were housed in a large rectangular box, in which you could add functionality by plugging boards into a backplane. At its most basic configuration, the ETC-1000’s input was through a front panel keyboard and hex display.

The system came in four configurations. The first three–labeled A, B, and C–were targeted to hobbyists or people looking to build a control system. They offered incrementally greater memory and features such as additional ports and connectors, cassette drives, and a full keyboard. The D configuration was aimed at the business market. It came with floppy disk drives, Electronic Tool’s FDOS operating system, and 32K of RAM.

The ETC-1000 was derived from an earlier Electronic Tools computer, the multiprocessor Etcetera System. The ETC-1000 is the central control unit of the Etcetera system configured as a standalone computer. Although the ETC-1000 came standard with a single 6502 processor, it could be run as a multiprocessor system, too, with optional 8080A, 6800, or F8 coprocessors.

My interest in the history of information technology is broad. I use my blogs, ClassicTech and Vintage Computer Photos, to build on the work I did for Collectible Microcomputers.
