Used in physics laboratories the Spark Chamber Scanning System used television cameras to record the location of cosmic ray events within the spark chamber. This information was recorded on tape and then fed into an IBM computer for further…
DEC's first 12-bit computer which introduced the instruction set that would later be expanded in the PDP-8. The PDP-5 had a memory capacity of 1,024 to 32,768 12-bit words (roughly 2KB-64KB). It was the first computer line in the industry with more…
The PDP-4 was 18-bit machine intended to be a slower, cheaper alternative to the PDP-1; it was not considered commercially successful. All later 18-bit PDP machines (7, 9 and 15) were based on a similar, but enlarged instruction set, more powerful,…
Circa 1960, Digital Equipment Corporation's (DEC) first products were a range of packaged logic circuit known as Digital Laboratory Modules. Built with discrete transistors the modules performed basic logic functions (e.g., clocks, pulse generators,…
