First release is finished: https://github.com/No0ne/ps2pico/releases/tag/v0.1 Great! I bought Pico right after the premiere, but didn't get too much time to play around. I had multple tries with USB/PS2 adapters for mouse or keyboards, but had mixed success, especially with mouse (USB to serial is …

Documenting all of the repairs and fixes that I have done to Toshiba T3200SXC (re-designed PSU, LCD adapter, speaker, wireless connectivity), once I'm happy with the results I will post them to the open source thread, but current files/schematics are here . I also made a short video with the repair …

Is the mainboard free of corrosion/battery leaks? There is a Ni-Mh RTC battery connected with a short cable in this laptop.

Yesterday I found out that my Trident TVGA8900D started giving a garbled image. It turned out, that a lot of legs on the video chipset have gotten loose. It was clearly visible under a microscope, the pins were moving, there are also black gaps: I fixed the issue by re-soldering the chip with …

It makes me wonder how much storage space would be required to store those 60000 CPUs a rough estimate would be around 5000/m³ that 12 times makes 12m³, stack'm 2m high, 2m wide, 3m long I could fit that in my room XD I was wondering about that too and quickly set up a scene, 80 stacked trays of 16 …

Also I'm not sure if these (really expensive) polymer caps are really needed as these weren't on the marked back then when 3dfx was alive. Polymer caps did exist back then (Sanyo OS-CON), and Voodoo 5 seems to be using them for the two biggest capacitors: oscon.jpg I don't think there is a need to …

Update: Now I have two MS6905 2.3 slotkets. They both have 75 Ohm resistor ladders, but one has TVC16222A chip and other has TVC16222 chip. One with TVC16222 chip also doesn't have additional small SMD capacitor on the back. The result: Each one of them works with 1400MHz 133FSB Pentium 3 Tualatins …

Easier approach was to take ws2_32.dll and ws2_base.dll from onercoreapi and place them in the same location as the goldberg dll and call it a day. I found out that Goldberg compiles by default with SSE2 as minimum requirement, now on the XP repository there is also SSE1 build. So it works with …

You can try VirtualDub or VirtualDubMod software. Or DScaler http://deinterlace.sourceforge.net/ (DScaler is meant specific for analog video capture, i think it also can interface directly with the hardware?) I think I used them for both PCI and USB video capture, but that was long time ago.

I would guess that the left one is TV antenna input, and the right one is video capture input. There should be some minijack adapters which can breakout these ports to antenna and RCA connectors.

Great, thanks for that photo, it's helpful! I have never seen the bottom side. It's a coppermine variant obviously, but now I can see that it probably also uses vias directly under BGA pads. So I should be able to see where these resistors on bottom and top connect. Though it looks like data traces …

this adapter would make sense if you make PCB interposer that converts it to Coppermine pinout It will be possible to solder it in such a way that it will work in Coppermine boards (i will add appropriate jumpers) May I ask why?

I prepared component symbols for mobile Tualatin and desktop Tualatin, most pins are identical but there are some differences: Pins present only …
