1.D.4 A1200 Timing Fault

[Stedy]

The Rev 2B A1200 motherboard also has timing problems, I have first hand experience of this!

Take a look at:

I have an Apollo 1240 and Commodore rev 2B motherboard, would not boot until I removed the capacitors.

You may be OK, it seems to depend on the accelerator you have and some Amiga Technologies boards were fixed.
