[Coco] Q on the extra chip socket the 2 meg kit uses

[Gene Heskett]

Greetings;

My coco3 has died again.  No clue if its oxidized gime or poor contact in 
the cpu socket.

That, in addition to my needing to design & make a new bit-banger path, 
somewhere in the salt to 6821/22 is a blown chip so my DW is DOA.  That I 
probably am responsible for as internal diagrams on the SALT chip are lost 
in the sands of time. The problem?  I fed it with the full 12 v + & - from 
my old XT PSU that runs everything, under normal use, running on 8 volts 
in the OEM design, a feedback loop in the DW from a miss-configure would 
not heat things up and destroy something, but on a full +-12volts, the 
salt and whatever got too hot and expired. New salt didn't fix it, so I 
need to start with a fresh 6821/22 and make a MAX-232 like interface for 
the bit-banger.  Once thats done, the salt chip can be removed.  Thats a 
job for eagle I think.

For those of you who have the 2 meg kit, the cpu is replaced with a 40 pin 
socket on the motherboard.  The cpu of choice is then plugged into a 40 
pin wire-wrap tailed socket on the 2 meg kit and the length of the wire 
wrap tails supplies the vertical height needed to make all the extra pcb 
stuff clear its surroundings.  Then another 40 pin socket is added, with 
the wire wrap tails plugged into it.

This serves as a bracing means to keep the tails all perfectly aligned.

But this extra 40 pin socket, which then is plugged into the socket where 
the 6x09 was on the motherboard, has very weak, thin solder tails on its 
bottom, and its both very difficult to keep them aligned so they will plug 
into the bottom socket, and the contact isn't a great contact once a bit 
of time has oxidized both sockets and solder tails.   And when plugging it 
in, you are working by feel because the surrounding bits hide the bottom 
socket so well.

So my question then, is does anyone know of a specific brand and model of 
a 40 pin socket that has substantially heavier solder tails, preferably 
gold flashed too?

Cheers, Gene Heskett
