I have a relatively slow instrument control application (responce times of 200ms acceptable) so want to use older hardware that I have for this. Wanting to run the application on an old PC using the run time engine. The application works with GPIB-USB-B so am assuming my only problems are with the driver for the AT-GPIB/TNT card. [link removed] says that driver 1.70 is required but [link removed] says that the driver is no longer availble for down load and refferes me back to the previous page (unfortunately I cannot find my old drivers at the moment). With latest drivers one of the AT-GPIB/TNT cards is recognised by MAX but will not talk to insruments and the other (slightly older version has jumper links for IRQ...) is not recognised by MAX. Suggestions please.
