I am certain the ram is upgraded. There were also mods to the case, including a cutout for a db25 connector (whatever was there is gone) and sloppy repairs to the keyboard cable. I would like to restore this one as It will give me a 1, 1b,2 and 3. I would like to confirm it is functional before I do a restoration. It does turn on and the keyboard works (it was disconnected when it arrived) basically got it for free with a purchase of 2 disk controllers, which both work.

At the very least, you can enter PRINT MEM. That will tell you whether you have 4k through 32k. To 
determine if you have 64k, you will need an ml program.
You ought to be able to find a test program at http://www.colorcomputerarchive.com/
