The system is taken from the book "Wisdom of Solomon", or "Wisdom", which was included in the system. The Sol-20 appeared on the cover of Popular Electronics in July 1976, where it was described as a highly intelligent terminal. In August 1976, the Sol-20 was taken to the Personal Computing Show in Atlantic City where it was a hit and took another year to complete.

The design of the SOL-20 was based on the Intel 8080 processor, which eventually became one of the most widely used microprocessors. The system had 8 kilobytes (KB) of memory that could be expanded to 64 KB, which was quite impressive for the time. The SOL-20 also had a built-in keyboard, operational display and cassette storage capabilities.

The SOL-20 terminal computer was originally designed as a simple terminal to communicate with other devices, but evolved into a full-fledged S-100 computer. The Sol-20 was the first fully assembled microcomputer with a built-in keyboard and television output, what would later become known as a home computer. This is thanks to the VDM-1 chip designed by Processor Technology that provided image generation.

This VDM-1 chip is designed to give an Altair 8800 an image generator, rather than relying on an external input and output.

What made the SOL-20 unique was that it was one of the first computers to be packaged in an enclosure that looked like a traditional terminal. This finally made it possible to connect and use the computer, making it attractive to non-technical users. The system came with software such as a BASIC programming language and a word processor, allowing users to get started right away.

The SOL-20 found its place in both home environments and small businesses. It was used for various applications such as word processing, accounting, games and hobby programming. Although not as well known as some other microcomputers of the time, the SOL-20 had a loyal user community.

Unfortunately, Processor Technology Corporation faced competition from other emerging computer companies and was forced to cease operations in 1979. This is the end of the SOL-20, but it remains an interesting piece of history in the evolution of computers.

Today the SOL-20 Terminal Computer is considered a rare collector's item. It represents an important step in the development of the microcomputer and contributed to the popularization of computers in households and small offices.
