In turbo2088.lzh you will find instructions on how you can run your
A2088 bridgeboard at 9.54 MHz. Mine is running fine since January 1991.
The main modification is the replacement of the 14.31818 MHz crystal by a
28.63636 MHz oscillator. To run at 7.15 MHz there are even no modifications
necessary! The only requirement is that your bridgeboard has the newer
FE2010A chip not the FE2010. With a NEC V20 Norton SI reports 3.7 !!
