[Maxima] macsyma newsletters

[N.A.Beishuizen at ctw.utwente.nl]

Hello,

Does somebody here on the list have the old macsyma newsletters lying around?
I noticed that some papers on symmetry analysis (like the overview of Hereman)
refer to macsyma newsletters 7(1990), 9 (1992) and 10 (1993), which describe the 
implementation of Lie symmetries (SYM.DE) and PDELIE in macsyma.

Maybe it is only interesting from a historical perspective, but you never know...

Regards,
Nijso
