I finally did the goof which I feared that I'd eventually do - plugged the power ribbon of my M303 reversed. 🤦♀️
Visually under a scope, I can at least see that a 22ohm 0805 resistor and a 40106 CMOS Schmitt-trigger weren't too happy about it. Going to try replacing them and hope nothing else failed.

Imaging the physical SCSI hard drive of the E-mu E4XT to BlueSCSI was a success and it has now replaced the spinning rust. The sampler is happily back in the rack with all the other old rackmount gear.

The internal disk is the original Quantum Fireball SE that was likely installed at the factory, since it carries the E-Mu labels.

Going to try the initiator mode on BlueSCSI to get an image of the hard disk on this E-Mu E4XT.

AmigaDOScember? The Pentium running MS-DOS still has a dodgy disk, so warming up a bit on the '060 in the meanwhile.

After desoldering the caps and cleaning up - yeah, those vias underneath are toast.

Finally got around to checking my stash of Gravis Ultrasounds for leaky caps like @adriansdigitalbasement.com advised and, uh oh.. This one doesn't look too good (spare caps above foreshadowing).
