Resources used by the HP-IL ISA card



I have on of those famous cards from Christoph Klug to connect the HP-IL world with the PC. However, as my computer does not have an ISA port I was trying to find a way to use these cards with modern computers.

During my search I found the following company Arstech that provides ISA-TO-USB adapters. They provide the adapter, if necessary power-modules for the adapters and the software to redirect the resources from the ISA card expects to the USB and back.

I have not gotten it to work (especially as they have forgotten to send me the Software) yet from studying their descriptions here and here it is apparent that I will need a few bits and pieces of information. My hope was that someone can help me out:

1) Power and voltage need: from the description and looking at the pins that are used in the ISA-HP-IL card, it seems that the card does need 12V as well as the usual 5V. Is that correct?
2) The simple power-modul will supply 5V and 12V current up to 50 mA I believe. Question: Is that enough for the card or does the card need more?
3)what base port(s) is the card using?
4) what IRQ does it need?

I do not have an ISA computer where I could plug the card in and then simply look it up in the device manager, yet I hope that someone might know the answers or does have the card installed in an ISA computer and be willing to look it up for me.

Last but not least for Christop, Diego, Tony and the other HP-IL engeneers, it might be worth while looking at the company and their product, as they also offer a SDK for their card. IF we can get this to work, it might make the connection of HP-IL stuff via Christoph's card with modern computers much easier/possible. Their SDK is described here

Thanks a lot in advance




I have a 82973A, it is 5V only (no 12V required). Base I/O port can be configured with dip switches (default is 1700). I have not seen the Klug Card. If the card is exactly the same as the 82973A, read the 82973A docs for the I/O settings. There is no IRQ.
