Panasonic 96 Port Question? Isoetic Question? Anyone Interested?

I just picked up 2 used systems taken out of service and have some questions -- maybe someone can help.

PanasonicVB43060 96 port system with following cards:

2-L-TRK 4-D-EC 3-A-KC 1-MFR 1-CBL(S)

There is one board (it has PB1190AJ on the rear) across the top on the left but no board on the right, although there is a slot for one. Is there a board missing, or is that an option slot?

ISOETIC EZ-1/18 WITH EXPANSION ASSEMBLY

3-80500 phones 2-80100 phones 3-Gray 83500 phones 1-80700 phone

Looking to liquidate -- Can anyone suggest who might be interested in this equipment?

Thanks in advance.
