I was reminded (I apologise I = foget by whom) that although PC/104 is electrically identical to ISA = signal-wise, it does not supply +12V (or presumably -12V) required for = ISA sound cards. The current draw is relativly low, so a 5V to 12V tiny DC-DC converter = solves the +12V problem, is there such a thing as a 5V to -12V or -5V to = -12V DC-DC converter to handle the -12V? Does it go under a different = name because I can't see any here. Or can I use a 5V to 12V one = backwards on the -5V to produce -12V? Regards, Nick ------=_NextPart_000_000B_01C167C0.92CEE960 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Diso-8859-1"> <META content=3D"MSHTML 5.50.4807.2300" name=3DGENERATOR> <STYLE></STYLE> </HEAD> <BODY bgColor=3D#ffffff> <DIV><FONT face=3DArial size=3D2>Hi everyone,</FONT></DIV> <DIV><FONT face=3DArial size=3D2></FONT> </DIV> <DIV><FONT face=3DArial size=3D2>As I mentioned before I would like to = use an ISA=20 sound card on the PC/104 bus of an embedded motherboard.
