The Amigo (or C/WP Cortex) had some interesting features. The display was handled by a 6502 which had a chunk of dedicated RAM, so it was quite fast and capable for its time (and position in the market). It was one of the first machines to have DRI's "GSX" portable graphics drivers, which were meant to give CP/M a standard graphics interface.
The CW/P version had a modified version of Wordstar set up to use the IBM-style function keys.
The Amigo was a system being evaluated by Ontel during 1981 as a new cost reduced system for the very low end.
The Amigo was designed originally by a company in Asia. Ontel bought the design and performed some minor modifications.
Initially manufactured in Woodbury it was a textbook Z80 design with Intel 82XX peripheral chips, very similar to the Ontel architecture except designed for lowest cost.
The system was based on the then advanced Zilog Z80 so it was capable of text editing using the single chip DMA, no stand alone DMA controller board was needed.
An OEM version of the Amigo was sold in the UK under the name CW/P
