Get your real service manual for your car and also get the another manual for your souped up engine too so you can get everything to work together nicely. To stop those ick, you have to go all out cleaning rest of fuel system. :( I used fuel injection filter from a truck with nipples for the rubber …

Try 33MHz or 40MHz using this DX50 CPU by changing crystals. If not, set board up as 33MHz and use a 5V DX2 66 CPU, either amd or intel. Cheers,

Verify that motherboard supports split plane socket (3.3V i/o and 2.8V core). Set clock and multiplier jumpers as Pentium 100 (Pentium 233MMX uses 1.5X jumpers to run as 3.5X internally at 66MHz bus) but set the voltage as 2.8V if motherboard supports 2.8V. Cheers,

Versa M/75 died last night. Looks like I have a board level repair on my hands, so I'll probably video that. I'm willing to bet it's PSU issues. So I moved everything to the P/75 for now (WiFi, FreeDOS HDD, etc...). In some ways might not be a bad swap since the P/75 does actually have a Sound- …

No again, the power supply is doing that. Motherboard is *not* the one that plays with power supply's voltage, the motherboard actually *requires* regulated voltages *from* the power supply which power supply is responsible for and must keep voltages within narrow range when current varies. Cheers, …

Look again and review your datasheets on implementing the reset circuit properly in warm mode reset cycle, if the host is not designed properly, might need to modify your card and the motherboard also. Cheers,

When this happens is there is a short window of time between good capacitor and dried up capacitor where slightly good capacitor is no good when cool but get better with heat always, the heat be it be internal or external …

No. I did not say fake. Just that Seagate had quality issues and I was careful not to use them if I have any back then and still is for me. I had to be careful with choosing one that is reliable would weary anyone trying to find Seagate hard drive models that are known reliable. PS: Seagate bought …

Smart thing to use gsmartcontrol No. SMART says read errors and seek errors count is too high, do not do anything to revive this and seagate SSHD is known to die once the NAND IC used up. Get another hard drive anyway that is not Seagate except for Samsung designed drives under Seagate brand, …

Use 50V SMD capacitor around 20nF or so they are not for smoothing, is for suppressing noise hence value is small. Cheers,
