I'm always impressed when kind folk donate machines to the museum.
In this case it's an excellent bloke called Chris Matthews who's donated this
never completed machine, and has built an enclosure round it to support the
buffer board and the extra memory board, which also looks unfinished. Apparently
there was a problem with memory timing, so Nascom came out with the Nascom 2
to address this problem. Knacks the owners of Nascom 1s, that.
There's also the complete documentation set from 1979 and an issue
of Computing Today which features the Nascom as well as several other kit-based
machines I'm now going to have to get my paws on :o)
More info will follow as I find it.
