I've Googled till I'm blue, but I haven't been able to find it. What
would be a good cross for a DEC 3639 PNP transistor? Or, failing
that, what are the specs for this transistor?

The DEC3639 is basically a 2N3639, and you can find a data sheet at
http://www.datasheetarchive.com/pdf/224396.pdf.
It's a PNP switching transistor. You can also have a look at
http://www.datasheetarchive.com/crossreference/2N3639.html for
cross-reference suggestions. NTE suggests the NTE106 as a possible
replacement.
I've gone through the module schematics on bitsavers and entered all the
cross-reference data from them into a spreadsheet. I really should get
the information up on my website someday.

I'm pretty sure that's just a 2N3639. There are inexpensive batches
of them on eBay all the time.

Most fo the time, for transistors, you replace 'DEC' with '2N'. Would a
2N3639 make any sense in the circuit (is it the same polarity, same
package, etc?)
