Version 6 DL dropped support for older Parallel port and ISA port interfaced Apogee CCD cameras. Why did you drop the support? You just obsoleted my $12,000 CCD camera! The Maxim DL manual states the following: System Requirements MaxIm DL works on Windows XP™, Windows™ Server 2003, Windows Vista™, Windows™ 7, Windows™ 8, Windows™ 8.1 and Windows™ 10. These older operating systems still support the parallel port, and I can still build PCs with a parallel port, so why remove the software support? Please consider adding it back in.
