    text: 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](/museum/open-university-uk-hektor-2/) 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.
