Thanks KonaLinda! I knew about the cards and the reader/writer.
Unfortunately, the mom never had those. :(
I'm not really that ambitious of an embroider right now.
However, I have an alphabet card that I'm pretty sure will get some use for DD4.
The usage timer is what I was hoping to find. The son represented the machine as having only about 5 hours of use on it as his mother had a stroke soon after purchasing it. He said that it sat unused for several years. I guess that explains why the case is so stained and the machine wasn't near as bad.
