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?

only this text on the PCB: KD10017-1

Reminds me of the Programable Sound Generator. John Kelly designed a number of pcbs post-83.

Re: A new unknown PCB may be for NewBrain

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
