Quoted from Averell:PB would be well advised to get out the schematics for the Heighway ALIEN.
What is the problem there... this is simply poor service?! People are supposed to buy spare parts but can't do any guided troubleshooting. Replacing parts on the off chance is unprofessional.
Not sure i follow your post...PB are making their own version of alien, not sure they are obligated to support the existing pin?
