Sweet, whilst waiting for a vendor to get back to me, I got my Model 4p's hi-res card working. Turns out, I neglected to remove a jumper that tells the TRS-80 the card is installed.
@sparcipx I just learned about the existence of the model 16 and its Xenix(!) port last night.
@alrs Yeah, the Model II and/or its children (Model 12, 16, 16b, 6000) are on my wishlist. A Z80 AND a 68000 in one expandable box, with Xenix as well. Who could resist?
