Does anyone have a Zenith Z29?

I've recently acquired a Morrow MDT 60, which, as far as I had always known, is basically just a Zenith Z29. Playing with it, it seems to have a rather brain damaged control character scheme, and insists on using parity no matter what. If you want a laugh, look at the MDT60 User's Manual, available on Bitsavers, and check out page 2-4 (PDF page 21). Even though switch 3 is defined as parity enable/disable, it's *also* defined in the table below, selecting which kind of parity to use... Therefore, it seems to me that disabling parity simply is not possible... Anyway, I took the back off and took a look at the board. Interestingly enough the logic board itself says "Morrow Terminal Bd", even though the casing and keyboard are clearly the same as the Zenith Z29. The monitor section itself definitely appears to be Zenith. I'm wondering if anyone has a Z29, if you could remove the back and take a picture of the logic board. It's really easy - three 1/4" hex cap screws and the rear pan just folds down. For bonus points, I'd love a copy of the terminal's ROM. I'm wondering just what is going on with this terminal. Did Morrow have Zenith make them? The other way around? Are the logic boards of the two terminals the same, with only different ROMs, or are they totally different devices? Is there any way to make the MDT60 not use parity and otherwise play nice with *nix systems? -Ian
