Most likely the PSU. The caps go in them, as do the opto isolators. Exxos have a recapping kit available.

Re: Native QL?

You could potentially create a "just-in-time" compiler which interprets the 68000 op codes and translates them into the native processor instructions and replaces calls the hardware or ROM with function calls. Similar to the way Java VMs speed up bytecode. This would generally be for allow...
