Old Nanoscope DSP cards

A typical error in refurbishing / reinstalling ISA DSP / Interface cards, is the default setting in BIOS for PNP ISA cards setting is incorrect for operating the ISA cards under WIN NT ( poss later Operating systems too ). If I remember correctly, you need to Disable PNP in the BIOS for ISA bus slots, ( PNP is Plug N Play ). Aside from setting up the correct settings for INT ( interrrupt ) setting on the DSP card and corresponding entry in the configuring the Z program upon initial start. This discussion assumes you are running WIN NT or later .... and corresponding Z version of the nanoscope program. If PNP is not disabled in BIOS the DSP is not properly recognized, but similarly if the INT setting is not set the same in Z and on the dips witches on the DSP, there are related software issues.
