    You will need the PAL upgrade to get the 6Mhz board to run Xenix
    3.x. This is documented in the Model 16 tech bulletins you can find
    in the model2archive. But, the required PAL chips are pretty much
    unobtanium now. There is a seller on eBay who had a few upgraded
    6Mhz boards for sale recently. He may still have some.

I think I know the seller you're referencing.  I don't see a hard drive 
adapter, so still looking for that.

Is the file for the PAL available to program new ones?  If the items are 
not registered, I can read out the equations.

    The 8mhz boards are similarly unobtanium.

I noticed.

    The Xenix 1.x and 3.x disk images can all be found in the model2archive.

OK, I'll see if I can make some disks from the images.  It'll probably 
take me a while to figure it out.
