Open University Hektor 2（PT-502）
Not much is known about this UK single board computer, also called PT-502. It was available only on loan to Open University students. The purpose was to teach electronic and computer engineers students how to conceive and build a microprocessor based system. The system was delivered with a peripheral board and a complete course enabling students to experiment both software and hardware problems.
More info needed about Model 2 and Model 1 (PT-501) systems
Oh yes, I remember it well..... (H)ome (E)lectronic (K)it compu(TOR) (!) or something similar.
I used one myself, as a part of my OU (Open University) studies c. 1986, for the course 'TM222 - The Digital Computer'. I think they must have originally been developed around 1981.
A bit clunky, I recall, but a great way of learning about microprocessor-based systems. In fact, I continued to use the HEKTOR user manual as a convenient and well written 8085 assembly language reference for about 10 years afterwards!
I seem to remember that a few years ago, when the OU revised the courses which used HEKTOR, and wanted to replace the (by then) ageing technology, they gave students the opportunity to buy a HEKTOR system for a minimal sum (but I can't recall exactly how much).
Since they were only for use with a few specialised OU courses, and were loaned to the students for the duration of the course, they are probably a bit of a rarity (at least compared to some systems), with perhaps no more than a few thousand ever made?
