I thought it would be easy to find a compilation of transistor data
listing the basic parameters (VCEmax, hFE, VCEsat, Pmax, fmax, ICEmax,

You might try here for the basic parametric data.

http://www.tehnomagazin.com/Transistors_data_and_replacement_tables/Bipolar%20transistors.htm

This is almost as much use as the T.D.Towers publication.

I'm trying to turn it into a spreadsheet, for easier use, but the
blank lines are playing hell with function - not to mention the line
count and last few descriptive fields.

I've looked at these tables more closely, and they seem to correspond
to the Towers format, though some parameter columns are missing ( book
bias for the hfe listed having once been one of the most useful).

Some isolated artifacts from the OCR are visible as single or grouped
digit typos, mislocated spaces, dust fleck decimal places or straight
garbage, but a good job on the main. Tehno Magazin appears to be
hosted in Poland, the Ukraine or Russia, so the small typo count is
even more impressive, given the language barrier. Some of the new
numbers may be approximations to soviet cyrilics. Good idea.

Going to have to resurrect the mfr, use and package lead-out tables,
for this new info to make any sense.

The first edition Towers boasted >20000 lines. This sheet more than
triples that count, with 20000 lines barely covering jedec jaida and
proelectron registrations.

As most of the numbers are now effectively obsolete, the OBS
designation has generally been dropped from the mfr source line and
replaced by the original oem identifier. Useful for historians,
anyways.
