Hektor 2

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

Kerry J. Morris reports:
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?

We need more info about this computer ! If you designed, used, or have more info about this system, please send us pictures or anything you might find useful.



I''m just about to list an original HECTOR on Ebay (uk) if anyone is interested.

Hi keira hope-thompson (london), I am interested in this kit. And The OU- Working with Hektor brochures (parts:6,7,8). How can I contact you?

This was the first computer I ever saw - my dad did the OU course, and as a young kid, I had time to play a little on it. If I remember correctly, it had a POKE sequence you could type in that caused the computer to play "The Entertainer".
Sadly, my life never really improved from this point, and for my sins, I''m a software developer now...
