This is the original first diskette out of two for my plotter. The disk contains very ancient material. Will only work for old CAD programs. And I have no Idea on how to install the win driver in the windows directory on the disk. The second disk is the MODEOCÚ COMM PORT driver. All it does is allow you to send HPGL and probably other types of files directly to the comm port via the MODEOCE.exe, could be usefull for automation tasks?
