Re: Grid 1537 ”Tempest” schematics

[Curt Vendel]

The owner tried them... Grid told him the design is owned by the US Govt 
and only they have the technicals on it... I was just hoping someone

them out the front door.

Complicating the matter is the paint outs are not just a direct staggered 40 Pin to Pin connection several of the through holes are not in use so just soldering on I had her and plug in the cable into it is not possible also the pens are staggered so that wouldn’t make it possible either.
