Checking interest for 2 plotters

[Graan]

Hello
We are moving our office and found 2 pen plotters. 1 HP 7475A and 1 Digital LVP 16. I Think the plotters are the same.
Rather than throwing them away I just wanted to check if there is any interest for these plotters. I might keep one of them (
I have tested them and the demo plot works and I have also tested to send serial commands and they seems to work. I dont have any pens so the tests were made without pens , but I saw the pen holder moving.
