[Coco] A General Purpose PCB is needed for the Coco Cartridge Port

[Kip Koon]

Allen,
I found the schematic and PCB layout files for a Slot Extender that was
created using the Eagle software that does just that.  After looking at the
files, I get an error, so ordering a couple of boards is impossible at this
moment.  Maybe they were created with an earlier version.  If anyone could
help me solve this little problem, I think we could have a real nice little
addition to the ever-expanding list of new accessories for the Cocos.  It
should not be too hard to create the schematic in Kicad, but I need a coco
cartridge card edge footprint for Kicad, before I could get a board or two
made.  What are the dimensions of those "fingers" on the PCBs that plug into
the cartridge port anyway?  Any help is much appreciated.
Kip

That would indeed be a nice thing. I don't know if it should be like all the
Arduino prototype shields.

.or if it should just be something that would plug in to a cartridge port,
then convert the pins to header connectors so one could build stuff outside
the CoCo.

Initially, I want a way to hook up something like a Teensy 2.0 to the CoCo,
or something like what Boisy is building for Arduinos. A "CoCo to Arduino"
board would open up some massive options.
