I've heard people talk about recapping the CD & power boards too, but in my case everything seems to work fine now, so I'm leaving it be until it breaks haha. Mine came from Japan, and I have noticed that devices with known bad caps do tend to be worse over there. Some first gen PowerMac stuff I …

Spent the last weekend and yesterday afternoon building a new logic board for my SEGA MegaCD. The previous one had severe cap leakage, leading to corroded solder joints that had completely let go on one side of the QFP. My attempts to reflow it just started to cause bent pins and screwed up pads, as …

Just unfortunate this one is dead What made you think the chip was dead? Have you tried installing the chip on the board? Or using a tester to examine the contacts? Do you know that the chip Banshee has unused contacts? I did install it on the board, and it didn't even get slightly warm, whereas …

Woah, nicely done. I've got to do the same at some point with one of my banshee cards that wasn't helped by a reflow. I also have the same card you have but it went from no VGA output to 100% working with a reflow so I was quite lucky there: https://www.vogons.org/viewtopic.php?p=1218210&#p1218210 …

This weekend, I reballed the PCI Creative Blaster 3DFX Voodoo Banshee a colleague gave me to try and fix. The card had artifacting issues on cold boots, that would slowly fade as the chip got hot. Once properly hot, Glide games worked just fine (starting them while the card was still artifacting …

I started the day with a bit of hybrid retro-ing. I became overjoyed when I picked up a stack of BigFoots (CY, TS, AND TX) and wanted to make a face for them. I've used spare drive adapter faces before and they work, so I threw one into the clone-o-matic and BAM! Faces for everyone! XD It just …

Otherwise, I wonder if this technique on the physical Macs can be used on Qemu PPC? It doesn't work on QEMU from what I understand, but most of the development of maciNTosh was done with DingusPPC, a relatively new PowerPC Mac emulator. Rairii has his own fork catered towards maciNTosh …

Never heard of fake CPUs, especially not during that era. Can't have been that common, but keep in mind it would be really easy to buy a CPU now, and make it look like a fake, then try to sell it as a "rare fake," or use one cpu to fake another more expensive one in the present day. Just saying. It …

Concerning the soldered wire, did some cards actually get sold like that with factory patch jobs or were they sold as refurb aftermarket products? It's a more common thing in the electronics industry. A small error in the PCB design slips through, that may cause anything from rare bugs to full loss …

They do exist from back in the day, but as a fully assembled CPU product with the AMD 386DX40 attached. They appear to be more common than the ceramic PGA equivalent CPU. I haven't seen anyone recreate it these days, though, which would be neat as there are cheap PQFP 386s available from China that …

So you made a new card with less noise? Or is there a trick to make the old one run more quiet? I did not, Keropi & Marmes did at one point. CMI 8330 is a very, very capable sound chip. I have 2 other ISA cards built using it, and while the noise floor is not comparable to MK8330 they are also just …

They do have some shielding, but I think specifically enough to be placed relatively close next to the monitor, not in front of it. Do you see any distortion or dark patches if you place them next to the monitor at a normal distance (eg. not right up against it)?
