Anyone know if a DOM (Disk-On-Module) would need a separate power supply when used with Qubide on QL?

Nope, I use one on my qubide clone

Yes, as Peter has pointed out, DOMs normally have a non-standard IDE connection that connects them to +5V. The QubIDE re-make supports that.
If you want to connect the DOM to a PC, however, you will usually need a separate Power Supply - Normal USB-IDE adaptors do not normally supply the DOM on this Pin. I use a separate USB connection to the Mac to supply the voltage.

Hi,

I have a 1Gb DOM in my Quibide, partitioned to 4 x 256Mb paritions.

It works very well without a power supply.

Hi

Many DOM and IDE adapters ( CF-IDE or SD-IDE) use IDE pin 20 ( an unused pin of standard IDE port) to get power.

My qubide clone has this functionality
