The Microbox II single board computer was a product of Micro Concepts in England, and was designed by Dave Rumball.
The Microbox II featured:
At first the only information I could find on the Microbox II was from an ad in '68' Micro Journal on page 56 in the March 1986 issue. But in March 2020 a member of the SS50 & SS30 Computer Bus Chat Facebook group page posted a picture of his Microbox II, and another member pointed me to additional information. Just a few weeks later I found another Microbox II owner in South Africa who has documented his board. Thanks Jarmo and Nadim and Wouter!
The Microbox II was featured in a series of articles in the UK edition of Electronics Today International (ETI) magazine:
Several decades after designing the Microbox II (MB2), Dave Rumball has done it again with the MB2K2, a tiny 80mm x 80mm board with custom hardware and software that aims be a complete emulation of the MB2 to the point of running the originalís software without modifications. Most of the individual LSI chips in the MB2 are emulated by one of the 16 RISC cores in the XMOS XU216 SoC (System on a Chip). The emulated 6809 processor runs at approx. 8 MHz. Dave Rumball recently posted more information on the MB2, MB2K2, MB3, and Image10 in his GitHub archive.
