Here is a serial port pulled from an IBM PC Portable 5155 or PC/XT 5160. The newest chip on this small 8-bit ISA board is dated from mid-1986.
The backplate has a DB25 male connector. The jumper block at U15 can be inserted upside down if you need this serial port as COM2. It is currently set at COM1. The jumper block at U5 is set for RS-232; rotating it 180 degrees changes the interface to 20mA current-loop.
The pictures here are of t...he card you will receive. I welcome questions from interested buyers.
I will make sure that it ships securely and promptly. I offer free shipping within the U.S. and a 30 day warranty.
