Hello,

The QL service manual indicates that all main boards returned for servicing should be modified to improve Microdrive operations.... Basically, a few trace cuts on the main board and a few bridge wires soldered between leads. (Different cuts and bridges for Issue 5 and Issue 6 boards). Has anyone every implement these mods and if so do you know what the specific benefit is and would you say its worth the effort?

Thanks,

Tom

Some of the track cuts and added wires are rerouting the power feeds. I can only guess why.
