My recent brain plan has been to try and make an Amiga "CDJ" using a raspberry pi and the Amiga software PT-1210, but the emulation isn't as responsive as actual hardware and for DJing that's an important problem.
I guess as it stands right now the cheapest way to do what I want to do is to get an A600 motherboard and stick it into a CDJ like box. It'd certainly fit but on top of that it's working out how to do the controls as the software uses the keyboard.
@renbymon I vaguely remember there being keyboard adapters which went from AT keyboard to A1200 motherboard. My A1200 Tower has one. Something like that might do the job? Then use an Arduino (other MCUs are available) to convert buttons to AT/PS2 protocol if you want say, a jogwheel or hard buttons.
@philpem I spent a bit of time yesterday working out exactly what buttons are needed and it just needs either 24 buttons or 21 and a push button rotary encoder.
I wanted to use a raspberry pi originally to save on cost and space, but now that the pi is out of the running (until something more real time with the emulation is developed I'm back to something more traditionall CDJ sized.
@philpem I'm not sure it's power but there's some lag somewhere in the emulation. I tried WinUAE and FS-UAE on a couple of machines and got similar amounts of latency.
I'll still give a Pi 4 and Pi 5 a shot :)
@renbymon Well, the Pi 5 can apparently do 3GHz CPU and 1GHz GPU, so that might be an option. And I'd read it's twice as fast as the Pi 4 at stock clocks - I assume that depends on workload.

Otherwise, could you squeeze a PC in?
