A new unknown PCB may be for NewBrain
I have a new PCB from Ebay, it looks like a port extension with 2 ports, however, I'm is not secure.
Are there any who have a straight print, and can one of you tell which ICs and more are used?

Hi
It is a port card for NB with 2 parallel ports.
Have a short time ago talk with a good friend, who knew the PCB.
Unfortunately, he couldn't say anything about which commands should be use to get in / out of it.
The big ic circuit is the Z80PIO
The Little is 74ls00
