+      I have just obtained an old Hektor III open university computer from 1983. Does anyone have a manual for this. Also it did not come with a power supply, so if you have the schematic then this would be usefull
+
+      Thanks

+      I have a Hektor III but it has a different ROM O/S from the one I used on my OU course. This ROM doesn''t give access to BASIC. Has anyone experienced this and indeed does anyone have a copy of the original ROM?

+
+Also very little information about the Hektor III. The case and keyboard were the same as the Hektor II but the electronic board was completely redrawn to support up to 64 KB of RAM and ROM.
+
+Several I/O connectors allowed to connect an extension card, a light pen, a 1200/75 baud modem, a parallel printer and even a mouse.
+
+The Hektor III was also loaned to the students for the duration of the Open University course, hence its rarity.
+
+Thanks to **Ian Hall** for all the pictures.
