Panasonic RQ 2709D portable cassette tape player, computer program recorder in original box

Vintage Panasonic portable cassette tape deck RQ-2709D - this is also made to function as an early computer program recorder according to the box and instructions. We plugged this in and it seems to run perfectly, I did not have any cassettes around to test but I see no reason why this wouldn't work.

It's in very good, clean condition in the original box. The box has some wear, but the machine and the cord look great.
