SBC's only work in backplanes, you cant stick one in a standard motherboard.
Re: Testing old caps with an ESR meter.
Posted on 2018-06-29, 21:17
I got some completely different values when caps were soldered. That 0.08Ohm cap that does 0.23Ohm via the cables meaured 0.45Ohm via the same cables when it was still soldered to my dead MS-6199VA board. I can't explain that one yet, let alone easily calculate some factor to subtract. Any ideas on …

BloodyCactus, if you are unwilling to provide the photo, you don't have to. I didn't think my request required such pre-aproval or justification. I'm still digging around, I have.. quite the un-ordered collection of thousands of parts here, ordered by project rather than just by IC... :) stocktake …

I want to see if they have the stereotypical Chinese counterfeit look to the text - faded brown, no markings on the bottom, perhaps a somewhat glossy look to the bottom (not always the case). Sometimes the font on the Chinese rebranded pieces looks off. I've been looking for genuine looking 10 and …

older non pc machines often had 1 head (c64, apple 2 etc), xt with 360kb disk had 2 heads, so no need to flip the disk.

88 will give you the most compatability. 55 comes up because some games were composed on it, but then you fall into trying to get a very very specific firmware version with the capital tones fallback. but basically any of the 88 series (sc-88, sc88-vl, sc-88 pro) will serve you fine. now a 55 will …

GM is a standard. songs played on any GM module will sound the same to an extent (ie: larger ROM allows better quality instrument sample), but for the most part, GM is GM. MT32 is pre all the standards, there is nothing else like it, and it was the first consumer oriented midi device like it at the …

sc880 is just a rackmount sc88 pro, so if you have the space its would be fine. Other rackmount stuff you could see that is gm compat etc would be something like Alesis S4 plus (plus is gm, non-plus is NOT gm). Once you leave MT-32, your into the GM era, so you dont have to limit to Roland modules. …

well there is a couple of honking big dpaks up next to the caps in the top left corner. I'd check the chips near the two blue jumper pin blocks, one between the ram slots and northbridge above agp slot and the analog devices one at the top between cpu + ram slots.
