Re: A86: idea for sybolic maipulation
Actually, the 92 system software was designed by the makers of DERIVE, a pretty
nice (at least the version I have) dos symbolic manipulation program. They
might (not likely) have some info about it at www.derive.com - not sure what
all's there (or if it even exists any more). I'd like to see that program
also...
