Hehe... Do you own with computer?

Because, it is just an expansion port adapter with some buffers / line drivers.
I'm pretty sure that you will find someone to build one for you for less than 20€.

I have a PPC 640 which I use with a parallel ZIP drive.
Before this video, using ISA cards was only a theory, the 2 ports were already on the machine but never used before. Now it's reality.
So, yes I will find someone to build it for me as I am not able to do it. Though I will wait a bit since it's a prototype at the moment, but a working one.

Sure, it is theory up to someone do it. ;D

The expansion connectors A & B pinouts are known and they are the ISA signals.

If nobody do it in the future from the PPC640 community, I will take a look for you.

There was a CPC guy from France going back a LONG time ago that made an ISA expansion for CPCs, what ever happened to that project?
