I was poking in old storage room and found some motherboard manuals. 10MHz Turbo is the only "lost-in-action" board. Other ones have somehow salvaged and running now. Older ones seems to be pretty simple manuals, but if someone needs a copy I can scan some...

I have couple of these 109-63000-00 MAC cards + couple of Xpert 2000 Pro 32MB 64-bit cards. Atiflash didn't want to read flash from MAC card, so though I was clever and replaced flash chip from Xpert 2000 to MAC-one. Of course it wasn't so easy. As a result I have ATI Xpert 2000 Pro 8MB with 64-bit …

Today I repaired Soyo SY-5EAS motherboard. Voltage level on Vcore was very low, 0.7-1.1V after MOSFET. Found broken shorted MOSFET by measuring voltage drop of gate resistor. Because MOSFET gate impedance is very high, there should be very low voltage drop. This one had several volts due to gate(1) …

I have also GA-586TX2, differences seems to be minimal. At least T2 has 75 FSB while TX2 maxes at 66. When I was young we had 586T2+233MMX which has been recycled long time ago. Now I have found exactly the same new boxed case and ready to build a replica.

Any tips on best place to store the boxes? 1.

I found this 486 DX-33 computer that has been lying in my attic for 20 years. Some understadable rust and a leaked battery. Had to fix one broken keyboard trace with wire. It still looks bad but works so far. Just wondering if DX2-66 could be used with this board. Should be possible because DX2-66 …

Now I have a feeling I should have been more specific with the statement - Voodoo 3 3000 AGP, nothing special here but for a good price could not miss. That is a great card, I did not mean to criticize... although Voodoo 2 SLI is more interesting to play with. Voodoo 3 just gives me anything new for …

You are right, checked the manual of 4.0. It turns out MSI has upgraded it in a way it no longer supports single voltage processors -> no-MMX Pentiums, Cyrix 6x86 or AMD K5. OT: Actually what did they change to gain K6-III support...?

I had the very same issue with Gainward 5VPA with VIA MPV3. It did nothing. After changing FSB/multiplier/memory jumpers back and forth suddenly it just woke up. Those things can be tricky and there are about a million things to check. Maybe I would just remove all jumpers and re-install them …
