Kandur, Is this what you need??

d_Edge).mp4

(Note the 40 pin connector marks, 1 to 1 arrangement) Not all of the 40 pins
were used by the EPROM, but all 40 are tied together with each card edge.

It will just be a couple of bucks more per board to do this that's all.

So far, I've been ordering them in sets of 3 from OSHPark.  That's the
minimum order.  I am charged per square inch.  If the PCB doesn't need to be
lengthened, the price won't change.  I could theoretically delete the open
notch at the top of the PCB and replace with the card connector.  This
should work well if the PCB won't be in a cartridge housing.  Not sure how
it would effect things if it's mounted in a cartridge.

I usually order another set once my last one has been sold.  Turn around
time is 2-3 weeks.  I can design and order a sample set and see how it turns
out.

Sounds perfect. 
How would that effect the price and
when will you order the next run?
