/n/sources/contrib/steve/historic/2nd-edition/pcdist/* there is some other stuff on there about the early releases which might be of interest. I have a copy of the 2nd edition cdrom, but that is still under copywrite so I cannot give you a copy unless you can supply me with a valid license serial number. This was printed on the business reply card that came with the original distribution pack from Harecourt Brace.
