I picked up a Honeywell-Bull AP-L laptop off eBay last week-- $10 with $15 for shipping out of Wisconsin. this is pretty much a SuperSport 286 rebrand.
The seller said there was no adapter to see if it worked, so it was AS-IS. I snatched it up thinking it'd be a diamond in the rough sort of thing...
I went and modified a 12v 4.3A supply I had so it was center negative at the barrel as is needed for it to power on. Flipped the switch... nothing!
so I opened it up and to my surprise, not only was I endowed with a very nice 40MB ESDI? IDE? hard drive, but a blown fuse on the power board! D:
using some wire, I made the fuse connection at the pins it stands on, and flipped the switch once more. I heard life! and then it shut off. and then... Magic Smoke!~
Seems a Sanyo Semicon SB80-05 went on me at D304 of the board. According to its datasheet (click), it's a Schottsky Barrier Diode? Rectifier? I'm not exactly sure, but it's 50v 8A, twin with common cathode. I can't seem to find any replacement parts for it on Mouser or similar sites, maybe I"m looking wrong. Can anyone lend a hand in steering me in the right direction? I'm a novice when it comes to these kinds of components but I sure can solder them in and do the heatsink compound job like a pro.
Other than that, there's also a D1667 transistor (Click for Datasheet) on wires I'll want to replace as well just to be on the safe side, and a bunch of capacitors which I'm about to undergo ordering replacements of and also raiding my local radioshack for what little stock they have-- I want this fixed quick!
so I need a drop-in replacement for the SB80-05 AND the D1667.

Okay, I wrote the above last night and didn't get to posting it until now. Here's the list of everything I need capacitor-wise as well, since this is an old power board and I do not trust the capacitors one bit:
16v 100μF x2
25v 47μF x1
10v 100μF x2
50v 47μF x1
10v 2200μF x2 (but these are probably fine, however I want to take care of them so I don't have to later.)
As of right now, I have a small bag I got at Radioshack of 4x 125v 4A fuses, so I'm set there. I picked up some 35v 100μF 85C Lelon capacitors that now in hindsight I don't think I'll be using. Probably a mixture of Panasonic and Nichicons. Can anyone recommend what type of both of these I should be going for? I know Nichicon has different capacitor types for different uses and I'm an idiot at remembering that sort of thing off-hand. if anything, I'll keep the Lelons for some other project, I have a router that needs a recap and I think these will work.
