I picked up an Applied Ingenuity Inner Drive with a bad power supply. It released the magic smoke and stopped working. Visually it looks normal.
I’ve fitted Vulcans with the MVLT80-4000-EOS PS but it’s a little harder with the ID so I picked up the same model of PS though it’s a later revision. I have several of the earlier revision and one that’s an intermediate revision. That one may be a replacement. Like the new one, the intermediate one has a place for a 7905 regulator but one isn’t installed and it’s 7905 is placed remotely. With the earlier ones it appears that AI added the 7905, they drilled a hole and used a bolt instead of a clip like all the other similar components.
AI appears to have removed the inductor coil and a safety capacitor after receiving the PSs. The PS won’t fit in the case with those two installed so I did the same and also installed the 7905 and cap on the circuit board. Also had to replace the fuse holder with a soldered in fuse because of height. Would have loved to mount the coil remotely but there isn’t a lot of room.
I guess it was to save a smidgin of room they soldered wires from the power supply to the hard drive and then installed them in the case together. I’m sure I can manage a 90 degree connector.
Wish I had a spare 8 bit hard drive to install. Haven’t decided how I’m going to go on that. It has built-in mounts for a hard drive and hard drives changed the screw position.
