Dunno yet how to transfer data from diskimages to WAV -no floppy controller here-, but I'll sure find out, as soon as I'm ready with the rest of the stuff!!


I used a Meanwell RT-50A power supply that I mounted inside an old Amiga PSU housing. Fits perfectly, is multi-voltage, and even has a handy on/off switch.

My solution was a 12V wall adaptor (DC), plus a small box for the +/-5V. The box contains a small DC to DC buck converter (LM2596?) board, and an ICL7660s for the -5V. The Lynx doesn't seem to draw much power, even under load. Maybe 1.5A? Anyway, I keep an eye on the voltages just to make sure they don't drift about.

I am tempted to put the box inside the case, because it is so small and doesn't get very warm. (eg. with a 12V barrel jack on the Lynx)

Caveat emptor, etc.


Volver a “Camputers Lynx”
