I tested some motherboard that maybe don't run but I don't know how now the supply when powered don't run the fan and make some strange popping noise like hot oil... I tried on different mobo and same thing and it don't even boot the …

Ok! I will buy both battery and some 0.01uf capacitors to replace but I've doubts this car will boot..

I've seen that on other positions on the mainboard there're others with 103 onto it (so 0,01uf ?) but the voltage? The capacitor a small like 3/4mm.

Well, cleaning up a 386 motherboard with vinegar I discovered bad traces but also some disk ceramic orange rounded component opened in half, they are labeled as "C6" for example so they should be capacitors but they didn't have any numbers into it. How can I know with what to replace it?

Thank you! I am going to look for that card but prices nowdays are just ridicolous for hardware that often need also repair. Just a technical question: the huge speed gap of the ET4000 is cause higher internal clock/memory speed or different architectur? it's interesting to see that no other pushed …

Thank! But compared to the S3 805 VLB card I tested on a 486, is it much slower? Did VLB vs ISA both 1 or 2MB cards differed that much?

I think that some trace is in fact broken where traces are blue... Vinegar like the usual usual cooking red vinegar right? 😁

Hi, I added on my (actually main/only desktop) computer with the already posted Am386DX-40, Eteq based mainboard, 8MB ram, Trident 9000i 512Kb config, 256kbyte of L2 cache (15ns chips) switching from the previous 64Kbyte 20ns configuration. Maybe I was expecting too much but the difference it's not …
Motherboard / PCB with battery acid
Posted on 2015-09-06, 17:01
Hi, I have to change some cmos 3.6v battery on a couple of mainboard that had battery acid on the pcb and dust so I'd like to clean it before soldering. I tried to use some eletronic cleaning spray but it seems it dry almost immediately. What can I use? The acid after so many years became of a blue …

- A nice VLB S3 P86C805 (S3 805 with a never seen old S3 logo like three S and 3 ) with 1MB soldered and another 1MB mounted - A nice QD6580W hard disk (2 IDE), floppy, game port serial and parallel VLB (?

But in Tron Legacy wasn't it supposed that the hardware was built and left in the dust before last Flynn login in the 80s? So I would expect server to be 386 based considering that no other poeple entered/upgraded that room for twenty years.(not talkin about the great out-of-discussion-capacitive- …
Re: S3 Virge DX 4MB vs Matrox Mystique 4MB

Wow nice answers. I am using both card on the VP3 Via chipset. I wanted to use the Voodoo1 but my mobo actually has always problem to get it running so a switched to a Voodoo2 8MB both with the S3 Virge DX / 4MB and the Mystique to test. Certainly the S3 has problems with 2D quality/speed at 1024 …
Re: S3 Virge DX 4MB vs Matrox Mystique 4MB

Mystique is faster in 3D, but has no filtering, so playing 3D games looks like playing in software mode. Is known also for its 2D image quality. Virge was lowcost 3D accelerator with fast 2D done by countless various companies. Had also problems with transparency (fog, lens flares). Depends on your …

The thing that I like a bit more on Tron Legacy of the other tech movies was that Sam actually used a command line realistic interface and that you actually can hear the sound of the old hard drives running up on the old servers when he is at the desk. 😉

Uh... Tron Legacy's server room is supposed to be a modern bank of servers. In fact, you see a shot in the movie of when Flynn creates the new grid where all you've got is the floor which stretches for infinity and a vast void within which to make a new world. He even mentions how Tron was created …

Hi, I would like to know what movies have you seen where actors actually used old or older computers to do impossible tasks for that hardware period/generation, obviously only for the usual 70s,80s and 90s technological wow effect were everything was possible even with some 6502 1Mhz cpu. :D Right …
