The unit and all components seem to only have minor surface damage and stains. All cords are in great shape with no significant wear, with one still in its original packaging. The POWER and R5232 lights turn on while the unit is plugged in, but it has not been otherwise tested, as I don't have the computer it is compatible with.
This is a highly sought after expansion unit for the TI994A computer, adding 32 KB of RAM and an RS232 and PIO interface. It's known for its compact design and quiet operation. This listing includes the power supply, a parallel port connector cord, and a three-way serial port connector cord.
I will be listing several items/accessories from a huge collection of video game/computer and other vintage electronics that I inherited. I either don't have the means, time or knowledge to test each item, therefore I'm selling everything as-is for parts, repair etc. This month, I will be listing several common and rare items for the vintage early 80's TI99/4A computer/video game system, so watch for more and thanks for looking!
