The machine works very well. It looks like almost new. I know the functions because I have owned one previously which went bad because I forgot the alkaline batteries that leaked and messed up the display a bit. It still works but this one is in perfect condition and works well.

The equipment is just a standard 74S and printer, but the casing is a high-density foam like found in some gun cases, or camera cases. Really protects the computer and printer. Not sure what company this was done for, but they did an excellent job.

This is a vintage item. Display has a streak but needs work. I am happy to acquire it. There is not much more to say. xxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx xxxxxxxxxxxxxx
