I agree with save2600.... pull that AtOnce board & put the 68000 back in it's socket.... then take the AtOnce outside, run a Humvee over it a couple times, burn it, then scatter the ashes at midnight in a graveyard. ;-) I used to work at an Amiga store, and we had nothing but trouble with those. If you need a peecee, well, much better machines than a 286 can be had for nothing these days.
