Actually the data that I want is indeed ancient! I am substituting
transistors from the 1970s and need to find better x-refs than ECG etc
provide. Some of the circuits used a specific transistor due to its
exact gain characteristics and others just don't work quite right...

So, if you do have that floppy lying around I really could use a zipped
copy (the return email address is quite valid - spam(a)fl...).

Thanks!

Yes, before they spun off ON Semiconductors. Then a lot of useful
information was taken down. All their old data sheets and application
notes were hosted by a contractor and it all disappeared, over night.
