Ugg, so ATX12V Spec, v2.0 was the last revision to "require" that the -5v line be connected. This was way back in February, 2003. Starting to wonder if I should scrap this entire system or get a different sound card for it. P3/500Mhz/slot1 - What are my limitations for sound? Should I avoid all ISA …

^ -5v rail was standard on AT PSUs but optional in ATX ones. Early ATX ones had it but a recent 500W with a -5v rail is almost impossible to come across. Take a look at the ATX plug the PSU has, see if you have a WHITE wire or it's missing completely. Chances are there is an empty pin on your ATX …

I got the SBPro to work just enough that I think it's not completely dead, and the LAPC-I, who knows, but I'm hoping it's still good. As far as I know, the OPL2 on the SB/SBPro1 is speed sensitive (or can't catch up with the rapid fire of commands it gets from fast machines, so to say). That makes …

also keep in mind that the LAPC-I requires a PSU with -5v rail to work fully, without -5v you won't hear sound from it Some of the boards I'm looking at have ATX power connectors and the PSU I have is a new EVGA PSU (Or Corsair maybe) 500W, Bronze rated, probably overkill now, but any reason this …

Recently found out that a P3 is (shocker) too fast for these old ISA cards, so now I'm setting out to build a system around these two audio cards. I got the SBPro to work just enough that I think it's not completely dead, and the LAPC-I, who knows, but I'm hoping it's still good. Can anyone …
