Not again ...
The Microbe(e) has few happy memories for me.
I was very much in the thick of it when the Microbe was a favorite toy in the NSW Department of Education. It was unreliable, the company was unreliable, and dominated by amateurs. All it had going for it was its cheapness, which meant that you could afford to more computers for when the others had failed yet again.
One of its serial weaknesses was the two-tiered design which created poor electrical contacts and was very much subject to problems with heat and just simple movement.
In principal, the whole thing was a good idea. In practice, very poorly implemented.
