RA90 (and 92) sets the unit number on the front panel buttons.

Here's how you do it:

1) Make sure both ports are disabled.
2) Press TEST
3) Press Write Protect
4) Use the port A and B buttons to select the number you want.
5) Press Write Protect
6) Use the port B button to change the answer to Y
7) Press Write Protect

With reservation that 5 and 7 might be TEST instead, my memory is hazy,
and I don't have any RA9x close by.
