I'd like to thank all who replied to my request for help a couple of weeks
ago. We obtained ptf5 and also had both IBM and STK check out the hardware

Sighhhhhhh! However, we know there is more fun out there somewhere with
our name on it. I can tell from all the fun the rest of you have been
having. Ain't life grand!!!!
