I've got my old one from B of A here at the house in Pleasant Hill. I'm only a few miles over the hill from you. It is a VeriFone unit model TRANZ 330. It's about 6" by 6" by 1 1/2" in size.
I think it still works, but BofA upgraded their software and sent me this one.
I only use the thing about 2 or 3 times a month for my mobile diesel smoketesting business. You can have it if it works for you.
Send me a pm if you're interested, and I'll pm you with my phone number so we can meet and you can get it from me.
