Hello all,
Not taking credit for this one - full honours go to Kaiser Sozei (partial LA replacement using a BA chip), Gladiator (full LA to BA change) and Romeo (prevention is better than a cure - Pin17 to 5V).
I have simply compiled it all into one page

happy hunting all - please note - use these and all my other help pages at your own risk - no liability will be taken for dead or damaged stations - these mods should only be performed if needed and only by experts.
