None of the DOS MP3 players produced sound which the PC card software could interpret correctly, and WinAMP seemed about the best of the Win98 players I tried. After some effort I found that my 133MHz 586 card could just about return a reasonable rendition of some low bit rate, mono, MP3s using Win 98 compatible version of WinAMP.not ideal. I found a variety of DOS and Windows MP3 players and tried them all with a selection of MP3s I had on the HDD. So I experimented using the PC Card as an MP3 player. I'd really like to have a meaningful use for my PC card in the RiscPC, but haven't really found one yet.Ī few months back (when my RiscPC was working!) I thought I'd found it - use the PC card to play MP3s, rather than stressing my StrongArm, and so leaving that free to run RISC OS.
