Re: Has anyone here had issues with Aliexpress?

My only experience with AliExpress was trying to buy a replacement flyback for a CRT monitor. The seller seemed legit, the listing had several pictures of the exact model I needed and it was apparently a factory that made transformers, they even included data about the company's history with …

Questions about adding S-Video input to CRT TV

I know this is not about computer stuff but it's still retro-gaming related and there's a few people with CRT knowledge here, so: Recently I got for free a cheap chinese-branded 21in CRT TV to use with my game consoles. Cool thing about it is that it is relatively new (2010 or so) and the Samsung …

Re: Retro Consoles.... who plays them

I only had an NES when growing up for a few years until we bought our first computer in late 1993 when I was 12 years old. After that I did play frequently on a friend's SNES at his house during the MK/MK2 craze and rented a MegaDrive on a few occasions, but I've never been a console guy. The first …

Re: Which of the three common mid 90s CDROM interfaces is easiest to find a working drive for?

I have one of each of these 3 non-IDE interface 2x drives, all are working fine and read CD-Rs somewhat reliably. This is my experience with each of them: Sony CDU-31A I got this one along with a CT1690 SBPro 2, they were probably bundled as part of an early multimedia kit since the card has a …

Re: Online account craze

Of course they need an online account, how else are they supposed to track every single thing you do without it? The one that pisses me off the most is Microsoft trying to prevent Windows users from creating a local account on their own computers. Isn't the ungodly amount of bloat and telemetry that …

Re: What voltage regulator to use for this board (EFA P54CNPCI) UPDATE: Vin and Vout are shorted to each other; not sure

Huh, so I was looking at the datasheet for your UMC L2 cache chips (attached below) and it seems they use a 5V power supply but they can interface with a 3.3V bus. So it seems a different design when comparing with my Soyo 029C2 which uses Alliance AS7C3256 SRAM chips that use a 3.3V supply. Good …

Re: What voltage regulator to use for this board (EFA P54CNPCI) UPDATE: Vin and Vout are shorted to each other; not sure

Can you try removing the cache chips and see if the short from Vcc to 5V persists? At least on my Neptune boards these are 3.3V chips that are powered by the same rail as the CPU. Maybe one of those went bad and is causing the problem. I believe the 430NX chipset does use 3.3V for some signals but …

Re: What voltage regulator to use for this board (EFA P54CNPCI) UPDATE: Installed regulator, outputting wrong voltage?

I also acquired a 3.3V fixed regulator, so I'm wondering if I could modify the circuit to use that instead. Yes you can! Of the resistors that adjust the output voltage (R182, R183), remove the one that connects to Vout and replace the one that connects to ground with a 0 ohm resistor (aka just a …
