[Coco] Nitros9 and Smartwatch

My suspicion is that the problem lies in the SmartWatch's being in ROM
slot 2 of the Disto controller.  I used to have a Disto Super
Controller (4 ROM slots), and to switch slots, you poked a certain
address ($FF41?) and pressed the reset button.

Why not try the SmartWatch in the first ROM slot to see if that makes
a difference? You can leave the cover off the controller for purposes
of the test, so you'll at least know if that's the source of your
problem.  If it is, you might be able to cure it by patching in the
correct ROM slot switching poke prior to attempting to read the clock.

However, once booted from the disk, executing getclk causes either a hard freeze or even garbage to appear on screen. swread and swset both say no clock found.

Since there’s not enough room to piggyback a DECB ROM, the Smartwatch carrier is just empty. I’ve heard that should work. The Disto controller ROM switch is set correctly to the Smartwatch slot.

THe time comes up as question marks and zeros. I then try the various commands to work with the smartwatch (are these commands documented anywhere?), but they fail as described.
