roger baldwin (UK)	Tuesday 26th November 2013	I have a PT501 in the original box with the manual, any idea what this would be worth? thanks

JW	Saturday 30th March 2013	I used one of these too (when I was about 10!) I seem to recall this board also had a temperature sensor input. Didn''t do me any harm - I''m now a software engineer.

Virtually no information about this training board that was provided, prior to the Hektor PT602 with a Open University course called 'Microprocessors and Product Development - a course for managers'.

The choice of the microprocessor is a bit surprising as the 8049 was more a microcontroller than a true microprocessor. Later, the 8049 will be commonly found inside dot-matrix and PC keyboards.

More info needed!

Thanks to Chris Millard for the picture.
