Umm...How can I find it ?...Where can I FTP it ?

CTPCI was written by a german magazin. Some articles and programs can be
found on several ftp-sites. The local server here is
ftp.uni-paderborn.de
/gigaserv/ftp/disk1/msdos/magazin/ct/pci
This is the local path, may be you don't need the first part.

Hope this helps,
		Holger.
