Here are some key milestones in DEC's early history:

DEC's early success was driven by their focus on creating affordable, interactive computers that could be used for specific tasks. This approach allowed them to tap into a growing market for computer technology and establish themselves as a major player in the industry.

The PDP-8 family was a series of computers developed by DEC, starting with the PDP-5 in 1962. This was the first computer outside the PDP-1 mould and was introduced at WESTCON in August 1963.

The PDP-5 was a stripped-down version of the LINC, with a price tag of $27,000, which was a significant reduction from the cost of core memory alone. 116 PDP-5s were produced until the lines were shut down in early 1967.

The PDP-5 inspired a series of newer models based on the same basic design, which would go on to be more famous than its parent. One of these models was the PDP-8, introduced in 1965, which replaced the PDP-5's modules with the new R-series modules using Flip Chips.

The PDP-8 was sold standard with 4 kWords of 12-bit core memory and a Teletype Model 33 ASR for basic input/output, and listed for only $18,000. This made it the first real minicomputer due to its sub-$25,000 price.

Sales of the PDP-8 were very strong, and it helped by the fact that several competitors had just entered the market with machines aimed directly at the PDP-5's market space, which the PDP-8 trounced. Eventually, 1450 "straight eight" machines were produced before it was replaced by newer implementations of the same basic design.

The PDP-8/S was an even lower-cost version of the PDP-8, with a serial arithmetic unit that reduced costs significantly, making the system sell for under $10,000.
