    I'm hoping someone might have a suggestion for my issue. Basically I'm trying to get a working ST-7E camera to work with a computer. It's worked with the system before, but I'm having trouble now. The computer is an Intel Core i5-4590 3.30 GHz running Windows 10 32-bit. Again, it has been working with this system, but it apparently was put in a new case which didn't have a parallel port. An ASIX PCIe parallel port card was placed in the case, but I still couldn't get CCDOps 5.x to establish a link. I did some checking and found that the I/O range on the card is not one of the three expected values for the LPT1, LPT2, or LPT3 sockets that the camera/CCDOps is looking for.

    So the question is, is there any way I can get this system to work? If my understanding is correct, I can't change the I/O range on the PCIe card unless I roll back to a pre-NT OS, and that even if there was a way to get CCDOps to accept the new I/O range, the camera can't be made to do such, so they still wouldn't handshake. Even knowing this, I still have to ask, is there anyway to keep this camera working for a little longer at least?

    Hi Robert, no, that's not going to work, and that camera has got to be ~25 years old, so unless you can find vintage hardware and OS, it's time to retire it. Plus the electrolytic capacitors in the power supply and camera circuit boards probably have dried out, so there will be ripple and voltages out of tolerance.

    The operating system has to allow direct access to I/O devices. So basically that means Windows 98/ME, although XP might work (I just can't remember).
    There were security changes Microsoft made that prevented programs from directly accessing the I/O ports, which was essential for the old parallel port devices. So if you do get an old OS to run, the next part is the parallel port I/O address and interrupt has to match the legacy PC ports.

    Thank you, Mr. Haig. You've confirmed what I was thinking. I was hoping there was a work around, but alas.

    I can confirm - Windows XP was the last version of Windows that supported parallel ports.
