The Adcock & Johnson Model 3000

Before laptop computers, there were transportable computers. Transportable computers (sometimes known as “portables” or “luggables”) were smaller than ordinary microcomputers and could be quickly moved and set up at a new location. Unlike laptop computers (which had yet to be invented) transportable computers had no batteries and needed to be set up and plugged into an outlet before they could be used.

Starting around 1981, there was a trend toward transportable computers.

The PMC MicroMate

The PMC MicroMate was a CP/M workstation introduced in April 1983 for the price of $1195.00, although that price was later reduced. It was sold by Personal Micro Computers, Inc, also known as PMC, already well known for the Model I compatible PMC‑80 and PMC-81 computers. Although the computer lines were not really equivalent, the MicroMate replaced both the PMC‑80 and PMC-81.

The LNW80

The LNW80, sometimes referred to as the LNW80 Model 1, was the first in a line of TRS‑80 compatible computers sold by LNW Research Corporation (later known as LNW Computers). It was probably the most successful TRS‑80 compatible sold in the United States. LNW Research had already created the LNW System Expansion, a replacement for the Radio Shack Expansion Interface, so the LNW80 was in many ways a natural next step.

When the LNW80 was introduced in 1980 it was originally sold as a $89.

The Tandy 10

The Tandy 10 was the second computer introduced by Radio Shack, although it wasn’t part of the TRS‑80 line. It was actually manufactured by Applied Digital Data Systems, also known as ADDS. ADDS (which still exists today as Boundless Technologies) was the largest independent supplier of video display terminals at the time. Unlike the TRS‑80 computers, the Tandy 10 was branded using the Tandy name (Radio Shack’s parent company) rather than Radio Shack.

The Lobo MAX‑80

The Lobo MAX‑80 was a TRS‑80 compatible computer sold by Lobo Systems (originally known as Lobo Drives International). Introduced at the 1982 National Computer Conference (where one could be reserved for a $100 deposit), the MAX‑80 offered an impressive array of features including:

a Z80B running at 5.

The Phoenix

One of the more intriguing TRS‑80 clones was the Phoenix, first advertised by Progressive Electronics in the August 1983 issue of 80 Micro. Designed by Keith Helwig, one of the proprietors of Progressive Electronics, the Phoenix was manufactured and sold in Lancaster, Ohio.

The Phoenix was offered in two configurations.

The PMC‑80

The PMC‑80 was the North American version of a TRS‑80 Model I clone that was created by EACA International Limited, a Hong Kong manufacturing company. Their Model I compatible computer was sold around the world by different distributors using different names. In Australia and New Zealand, it was the System 80. In Europe, it was the Video Genie. In the United States and Canada, it was the PMC‑80, distributed by Personal Micro Computers.

The TRS‑80 Model III

Radio Shack introduced the eventual replacement to the Model I, the Model III, in 1980 (the Model II, introduced in 1979, was part of a separate line of business computers). Unlike the Model I, the Model III was an all-in-one design; the monitor, keyboard, and disk drives were all in the same unit. This cut down on radio interference and helped with school sales (which were concerned with students walking away with computer components in their bags).
