@ Fragment

Here's mine with the patches discussed before..

Could I use that Mobo picture for a tech note on A1200 motherboard fixes?

Your board has the PCMCIA fix, timing fixes and something to do with Paula I can not work out.

@Animagic

The REV 2B board had a few timing bugs that needed to be fixed so that it worked with all A1200 accelerators.

All rev 2B boards need a mod. I'm surpised your Apollo 040 works well with yours, mine did not.

The boot up problem, have you cut pin 1 of the IDE cable?

Hello,

The main modification for the timing fix is to remove 2 resistors from the underside of the PCB see

Note: This pic has the resistors in place, another one has them removed (writing a guide ATM).
