This teardown that thegeekgroup did reminds me of technology gone by. There are lots of variations of this. The one I used had a different type of ink ribbon cartridge it was a ink impregnated cloth that would auto recycle so your text would just get fainter and fainter over time. If you want to change the font you just replace the font wheel. I am surprised that there is no sensor to prevent it from typing if there is no font wheel or ribbon cartridge. Interesting that there was no cover on the EPROM. I am thinking it must have been replaced by a field tech since I am sure it would have been covered out of the factory. One thing you can see is the construction and drive train was designed with serviceability and longevity in mind. I would like to see what it would look like if it were built today. It would weigh about 5 pounds and last about a year printing a few pages a day. With a bit of work 2 of these printers would make a nice small CNC machine.Â
