https://en.wikipedia.org/wiki/Epson_Equity ... all there

I have both systems (Equity I and Equity I+).

I haven't fully disassembled the Equity I, so I don't know all the specific details of its motherboard. But from what I can see of the Equity I board, it looks like it has a different layout than the Equity I+.

Of course, the Equity I is an XT-clone (4.77MHz) while the Equity I+ is a 10MHz Turbo XT.

Is there anything specific you're looking for with respect to the two motherboards?

Wanting to know if the 1 uses asivs at all. I know the 1+ does. By comparison ibm 5150/5160 mobos don't use any. Just Intel and 7400 chips and ram/rom.

An actual photo of a 1 mobo would be super nice.

Here's some photos.

That definitely does the trick.

Only 1 horrid little asic in the 1. Perhaps not enougj to be a deal breaker. I've been holding on to this pristine epson keyboard. Wondering if I should go ahead and buy a cpu. Many thanks.

Can the Equity 1 use a vanilla pc compatible keyboard?

Actually there seems to be 2 asics. Not sure what those part numbers represent. Don't feel like looking them up right now.
