Not exactly PC hardware, but definitely retro.
It's a dirty old dial-up teletype computer terminal from TI. You could use one of these to connect to a remote computer via the phone network back in the late 70's and 80's.


Made in USA. How often do you see that? 😀
Has some sort of mechanical keyboard from what I can see, very similar to the Commodore 64 keyboard. It uses standard fax thermal paper for the output.
After I get a power supply for it, I plan to strip out the dial-up circuitry and replace it with a simple serial decoder so I can connect to PC running SimH and pretend it's the 70's again 😁
