Denny,
The best way to have the people here confirm the model of your machines is by posting pictures. Plus we all love to see them, lol. Also, one way to tell if you have a 128 or a 28 is by measuring them. One is smaller. I forget which one, but there are many others here who have that memorized. So, I just think of it as not my department, lol.
Welcome, and I have to second leonf's idea about that Spartan, lol.
