A/B Manual Switch, Parallel Port, 2-Position, Data Transfer Box
You are offerding on a lightly-used 2-Position Switch, A/B Parallel Port, Manual Data Transfer Box. This device provides three Parallel connection ports on the back. Also included is a heavy-duty 10-foot parallel port data connection cable with male (25-pin) fittings at both ends. I am the sole owner of this switch and connection cable. They are in excellent condition.
This device was only used on a few occasions when I needed to connect my desktop computer to a desktop laser printer and a Zip Drive backup at the same time. This was accomplished by plugging one end of supplied the parallel port connection cable into the parallel receptor on my desktop computer, the other cable end connected to the top receptor on the back of switch box. I plugged parallel cables from my printer and my Zip drive into the bottom (A & B) receptors on the back of the switch box. By simply turning the knob on the front of the switch box from A to B, I could quickly alternate between devices. This switch box could be used in the same manner to transfer between various devices that use parallel connection ports.
CONDITION: Used/Excellent Condition. I purchased this A/B Manual Switch Box and Parallel Cable new approximately 20 years ago and used it occasionally to back up data from a desktop computer in my home office. It has always performed flawlessly. Subsequently, after purchase of a newer desktop computer, I placed these peripherals in storage in my non-smoking, climate-controlled home. I’m now selling the older desktop and no longer need to print backup records stored on Zip Drive disks. So I no longer need this transfer switching device.
