Interesting product. Pretty clever how the bus is expanded.

nice but it would have been nice for others working on this for you to have held up the backplane for a few seconds without your hand covering the power connections, so those of us who are working on these without the markings being clear can have a look at yours. Folks like me. :D

🤣 Sorry, you should see how much I edit out my big head and or hands.

I'm interested in buying one of these but what's the actual name of the product?

[@drueking]

I keep a search set for notify in Ebay for “Tecmar Expansion”. It usually notifies me for either the unit itself or cards that go in it.
