I have read that the XAP1541 interface usually does not work with PCI or PCI express parallel port interface cards due to the required hardware interrupt not being implemented for these cards. Is this correct? If you know of a specific card that does work, please post the details. Also please list what OS you are using. I have been using my XAP1541 with my old Windows 2000 laptop. This works ok, but I am starting to think about longer term. |

Hi, recently volunteers to OpenCBM did some testing with the linux part of the project. We found out that any PCI LPT card we had for testing does not implement the hardware IRQ function correctly. There might be workarounds, but this would introduce just another more sophisticated X-cable standard, not to speak from software modification to support this mess. We're still in the hope that with more modern updated and new PCI/PCIe LPT chipsets, hardware developers will learn how to successfully adopt edge triggered ISA bus hardware IRQs to level triggered PCI bus hardware IRQs. Maybe this requires a per-board interrupt controller or something like this. At least under Linux we see the small chance that such cards will be supported by updated drivers. But, currently we don't see such cards and it's more likely that the xum1541 goes into mass production and replaces all the older LPT port based cables. Womo |

Thanks for your feedback. Long term, I might go with the XUM1541 cable as long as I can purchase one that is assembled and tested. That is a bit too difficult of an electronics project for me to do on my own. Meanwhile, my current setup will suffice to continue to scan in the last of my floppies and as a transfer medium for my very few cartridges and cassettes. |

I've been helping Jim Brain prepare for production of the ZoomFloppy. He's said it will be available by the end of 2010. So hopefully we can end all this LPT nonsense soon. :) |

I know exactly what you mean. It was a long hard slog for my computer dealer and builder to get a motherboard with a printer port that worked without requiring any windows or Linux drivers. for reasons I'd rather not go into, I also require a working serial port as well. |
