Hi guys, recently aquired one of these without power supply.
It has a 5 pin din input on the back and I cant find anything about voltage requirements, anyone had a go on one of these before?

That's an Excelerator FSD-2 if I am not wrong, so you can either source an Excelerator power supply or follow this pinout:

The pinout for the Oceanics / Excelerator Plus drive power supply
connector is as follows. This diagram is shown facing the rear of the
drive.

      +12VDC @ 1/2 Amp ------4         1------- +5VDC @ 1 Amp

                 Ground ------2       3------- Ground
                                  5------ no connection
                             
Although the supply specs are the same as for a CBM 1541-II / 1581
supply, the connector is different. A Radio Shack # 274-003 DIN
connector will fit the Excelerator drive.

Reports on Lemon Amiga say that Excelerator is a relabeled MASTER-41. This proves it:

It's a good disk drive, many times more reliable than Commodore's drives. I used to have one myself.
From the looks of the pinout I am almost sure you can use a regular PC PSU to power this thing, provided you have the right plug. I think you can modify (extract one pin) of a 6 pin DIN plug to make this connector.

It'd probably be more worthwhile (and cheaper) for me to try that out that venture. Kinda handy i've picked up an old pc to gut out smile

Sure, making a PSU from scratch sounds like a nightmare. The PC ones work well for most of these things. You have +12VDC and +5VDC in a PC PSU, you just need to measure if you have the right amount of amperes on each line.

Good luck!
