Port Expander cards.

Postby vicassembly » Mon Jun 12, 2017 1:50 pm

I probably have 10+ expander cards in my collection and use the Golden expansion extender for every day use. I am including a couple of pictures of some that are either home-grown or have some other unknown origin. Ever seen anything like these?

Top one looks to be a Cardco Cardboard/6

Bottom one appears to be a Dataspan-50 as seen on Rick Melick's page

It's a rotary switch, you use it to route /BLK5 to a specific slot.
