Thanks for the replies, seems odd that there a location that looks like it was for a socket but there’s nothing there and it says 486SX whereas the socket itself says 80487SX. It's for variants of the board that come with a 486SX soldered in that empty location which you can later upgrade by …

Batman's Revenge has a Mercury chipset, so no EDO support. You have to use FPM sticks.

Other than the Fuhjyyu caps, it looks good: standard topology for AT units, adequately sized parts for the specified ratings, 18AWG wires, input filter with safety rated caps, LM339 comparator and fan controller. Not bad, CWT designs are decent but they had a love relationship with Fuhjyyu that ends …

Agree with momaka, this unit, if fitted with good quality capacitors, is very decent. Great even, considering that 230W is more than enough for your typical AT build. More importantly, given how it’s built it can achieve the specified ratings which is what actually matters, so I’m not sure why some …

Look at one of the corners of the ceramic package, there should be either a 63 or an 83 engraved indicating the speed. Or just remove the fan and check the part number.

Also, not all Plato revisions support 66MHz FSB, so in that case not even a P100 would work. So make sure what version of the board you have.

I have an ECS SL-486E EISA board paired with the VI-833 which is the ET4000AX-based local bus graphics card. Interestingly the card itself is basically a Genoa 7900, uses the same BIOS and drivers. The card has a jumper to be able to run at 50MHz FSB, otherwise it doesn't work, so that probably adds …

Like the rechargeable one the board originally had? Sure, but you don't need the external connector for that one, just solder it where the old one was. Of course, if you use a NiCd barrel battery it will leak over the board at some point if it's not removed. But it should last a few years.

Those external battery connectors in old boards use the two outer pins, 1 and 4. Usually 1 is connected to the battery + and 4 to -, but you should check because it's not always the case. The pin that is connected to ground will be the battery -. What you can do if your pack has a different …

I'd say most of the pre-PCI 486 boards that are not intended for OEM systems would satisfy that condition. The only integrated I/O "feature" would be the keyboard connector and you need to add in graphics/sound cards as well as multi I/O controllers for serial, parallel ports and drives. Later …

- Check the DC-DC converter before soldering in to the socket. Use an 2 ohm/10W resistor to simulate the load and measure the ripple with the scope. Check the thermal condition of the converter. Please note the converter will be in a much hotter place next to the bottom of the CPU. Use high …
