Hi Bruce

I could dig out the old computers with the old version of PBP and give it a try.

Unfortunately there a many old computers in various stages of being canibalised in my garage so it could be a bit of a mission. There again the old original PBP flopy disks must be some where.

I will see what I can come up with at the weekend. Being an engineer is a curse some times, one has just got to get to the bottom of an issue no mater what.

Thanks Again
