Introducing the Micronix 80HD - a complete microcomputer on a single board

Single board computers - like the Raspberry Pi - are still quite popular, especially with hobbyists as they're often small and have low power requirements. 

The fun with this advert is that whilst a modern single board computer might be more-or-less one chip with a few other components, and be no larger than a pack of cards, this one from Micronix had over 90 chips on it and was not far short of the size of a piece of A3 paper, although to be fair it was aimed at the system-builder market rather than home builders. 

A 64K model retailed for £445, or about [[445|1983]] in [[now]] money.
