But I have no idea how to tell the ROM version.

I realize that this is not the model that you are looking for, but I am curious to find out how to tell the ROM version.

It's not 100% confirmed, but when you run the self-test and get the 32SII-OK message, either the 0 or 1 anunciator will be displayed. This is believed to indicate the ROM version.

To run the self-test, hold ON and press y^x. Press any key to step through the tests until you get to the keyboard test, then press each key in order, starting at the top left (square root), and proceeding left to right, top to bottom.
