Nixdorf LK-3000 Computer in box w/ power unit lights up

Description

A clean example in box. Instruction manuals and zip up case are present. Mild wear to the box.
I found the original Nixdorf power unit, so I was able to turn it on. It lights up, but as I don't know how to operate it, I didn't try any other functions. It does power up and the display turns on.  Sold 'As Is'. No returns. From a well kept estate.
California residents must add 8.75% Sales Tax or provide a valid California Resale number. No exceptions! Shipping via the USPS.
I have been a USED and Rare Bookseller (Gerry Kleier Rare Books) for 40 years, so I'm generally accurate in my descriptions and will pack everything well!
