Need Blaise PTP 5.1

I am (still) searching for a copy of Blaise Computing Turbo Power Tools
Plus version 5.1 (or later).  I have already contacted TurboPower and
they only bought the Blaise customer list - not the product line.  If
anyone knows where I might buy, borrow, or rent a copy of this software,
*please* let me know.

Thanks,
