There was another one like that which was advertised for years in "Practical Electronics". The idea was that you built it yourself, bit by bit, and added modules as need arose (and pocket-money permitted), and then programmed it. It looked like a quality build, based on the good old 19 inch rack system.
Geoff, I'm sure
I know the ad you are talking about.
Tomorrow, I'll have a looksee through all the old 'r&d' stuff I have around the house.
