I have one of these boards with the 28.63636 MHz oscillators.
Never noticed it until we started discussing which crystals
were used on the IIs. I have other IIgs's that I can look at
to see which crystal they have. One of the ROMs on this particular
board is an eprom. I should look into this further. I had 5
of these boards at one time but sold most of them.
