Have you looked here ? The MASTR Index of GE Conversion Information - MASTR2 Dot Com
I assume your up Island with the area listed as Cumberland/Comox Valley and your a BC -Ham ?
I know in lower mainland there are still those in use, there are numerous knowledgable guys on 220 that I could point you to, so I am sure someone in lower mainland has the software.
There are two Vancouver area stores that are run by hams as well you could call.
