Ben: The PIC-Master works fine on Pentiums (under Win3.1x and Win95). Your problem sounds like a PCI/ISA configuration error, or an address conflict with one of the other cards in your system. Make sure that the PIC-Master interface card's slot is configured as an ISA slot, then ensure that the card's DIP switches are selecting an address space that's unused by your other cards, then run the PICMASTR.EXE or MPLAB.EXE software and verify (in the "Hardware Configuration" dialog box) that the software's looking for the card at the correct address. If a PIC-Master manual didn't come with your used system, you can download one from the Microchip web site at: http://www.microchip.com Hope this helps... -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering - Vista, California === http://www.geocities.com/SiliconValley/2499
