[GreenKeys] BASE 15C

[Peter Leonard]

Hi,

I have a number of various Model 15 components. 2 Bases, 2 Printing units, 2 keyboards, 1Tape distributor, 1 case and 2 keyboards for tape punching.
All are far from perfect but appear complete. I do have access to a large range of NOS spares.
My task is to refurbish and produce a complete working system.
At present I am trying to decide which base unit to start with and I have noticed considerable variations between the two.
The unit in worst condition is marked 15C and is fitted with a terminal strip marked 21-46 and is equipped with the holding type magnets.
The better unit (marked BB-44 on a brass plate) has three terminal strips with six terminals each and is fitted with a line relay and circular (puller) magnets. There is also a 4 terminal socket arrangement adjacent to the fuse, nothing connected.
I have a schematic of the standard 15C base but cannot find a schematic of the other. Is anyone able to point me in the right direction?

Thanks

Kind regards,

Pete
