I'm not sure what you really mean by convert. Floppy disks aren't a particular platform, other than how they're formatted - the formatting process sets up the disk as an Amiga, PC, Acorn, Mac etc....

I think they're standard sound cards as opposed to MP3-decoding DSPs. So while they'll produce nice quality sound, you won't be able to decode the MP3 fast enough to produce the sound in the first...

If you're talking about PC disks as in HD type floppies, it could be that the drive is detecting the HD indicator on the disk and producing an error since the Amiga can't actually deal with HD disks....

Bottom line, there aren't really any accelerators as cheap as the ACA1221, let alone one with an 030. The 030 tends to be a sweet spot for WHDLoad machines, able to play the more intensive games as...

Yep, that's pretty much it. Coupling is also a means of blocking a DC bias in an AC signal, so it might not necessarily be any cleaner, but will be centred around 0V.

Well, a long story short, decoupling caps are generally needed in digital circuits because switching a logic line from high to low causes a reversal in the flow of current. This in turn...
