Hi,

With the current discussion of prototpye boards going on, it brought me 
back to an idea I was considering ... I am planning on making a few of 
these in my next batch of PCB's

The idea is that you would plug one end into a slot and the other end 
could take a variety of 50 pin connectors that could be soldered across 
the fingers.

(pictures are examples only)

25 x 2 shrouded header -  http://www.cadforum.cz/catalog_en/file.asp?blk=947

These first two would work well with old internal scsi cables.

Use a std perf board that has a 50 pin angled header soldered to it, you 
could plug that into the top of the board slot adapter.


or you could use a board edge connector like these

connected to a ribbon cable.


I also placed a dual row of holes on the face of the board so that a 
header could be connected out the side for logic analyzer leads or 
anything else you can think of.

I was wondering if there was any interest in my making batch of these up 
for sale.

Price would be approx $6 each or 3 for $15 (bare boards only - quality 
PCB with solder mask and silk screen) - if gold fingers were required 
then the price would basically be double.

Send an email to sales@a2retrosystems if you think this is something you 
might be interested in.
