This was a combined Nascom-1 buffer board, power supply & and bus system. Super indeed! The edge connector at the right-hand side would be linked to the Nascom-1, mounted back-to-back on the reverse of this board. The connection was made via 2 connectors on a short piece of stripboard, referred to as “micromum”!

The complete assembly was reasonably rigid, especially if some sort of insulated packing piece was used between the two boards.


This was one of those lovely items that I completely failed to get on ebay. Luckily there were some lovely pictures. 🙂




And we have the manual too: GM806_Manual

An advertised part number for this is GM806AK. The K indicates that it was a kit version (I don’t think they were ever sold ready-assembled). The A indicates that the kit does not include power supply components, which were sold seperately.
