MC3340 or RS 306-803

[ppppenguin]

The RS 2983 scan that I linked to is presumably the same as your paper copy. Nowhere does it explicitly say that the chip is a MC3340 in disguise. That was back in the days when RS sold everything udner their own name. It took a while for them to realise that hiding the original manufacturer ID was not a good idea.

I suppose that philiosphy dates back to the time when Radiospares (as it then was) didn't sell valves, transistors or chips at all.
