Nascom 2 - Advanced Z80 Single Board Computer


Following on from the success of the Nascom 1 came the Nascom 2.  This can be thought of a Nascom 1 + Buffer Board + extra memory sockets, running at 4MHz.  The whole package is mounted onto a 12x8 inch PCB which was big enough to be a challenge to build.  To finish the package off was an 8K ROM based Basic supplied by Microsoft (I wonder what ever happened to them?)

The board was designed to take 8 x 4118 1K RAM devices.  However, a world shortage of these devices forced Nascom to supply memory via DRAM memory card (RAM 'A').  This extra expense proved to be the beginning of the end of Nascom.
