Audio/Video/MIDI Devices

[aeroc]

I recently bought a decently sized Amiga lot locally that came with a lot of audio, video & MIDI devices that I know little about. I only have interest in keeping the systems and games that came with the lot and I'm having a hard time determining whether these extra devices have any value. Is this stuff generally worthless?










Also, does anyone recognize the Transcopy 3 card, is it for an Amiga system? And is that 16Mhz 68000 accelerator worth little since there are much better Amiga accelerators?
