[Coco] MPIs & Cartridges With Solder/Tin Contacts Can Now Be fixed With A Gold Contact Plug Upgrade!

[Christopher Smith]

I did find that one cart I picked up with a pile of old CoCo stuff appeared to have the contacts actually worn down.  It still works, but it's not easy to get it in just the right spot; anyway, it looks like the tin is completely rubbing off, but it doesn't seem to have been well cared for.  The next problem is -- as someone else said -- I'm not sure exactly what you'd need to do in order to attach a connector like that to a cart in the first place.  May not be the easiest thing in the world. :)
