The Puhui T-962 is a cheap IR reflow oven that has been around for many years (the earliest occurrence that I’ve found is from 2007). It has some serious and not so serious flaws that many blogs have already addressed. Known modifications include: Proper grounding, replacing the insulation tape, custom firmware and additional temperature sensors. Some people go even further and replace the system fan and controller board, add more powerful infrared heating elements or an additional fan for better heat distribution. I have included links to all of these modifications at the end of the article.
I bought the T-962 last November to have some support when soldering SMD components. But before I could use it for the first time, I had to take care of the most critical flaws.
For upcoming experiments, I was in need of a working CD-i player with a Mono IV mainboard and 8 KB of NVRAM. I checked my basement and found a broken CDI470/20 that had been sitting there for years. Previous repair attempts had failed and I hadn’t bothered to look at it since.
Upon the first start, it greeted me with the memory full error:
When taking new screenshots for my old PC-FXarticles, I noticed that my PC-FX mouse (FX-MOU) didn’t work properly anymore. It still detected the movement fine, but if failed to register one of the mouse buttons. My spare mouse turned out to suffer from this too.
It’s time for a quick repair. Two screws underneath the label hold the mouse together (marked with yellow circles).
This is a quick fix for my Apple Power Macintosh 7500/100. It doesn’t have its own article yet and has only been mentioned a coupleoftimes. This article also isn’t about the Power Macintosh itself, but about the graphics accelerator that the previous owner had built in. The Formac ProFormance 3 Plus was advertised as “The Fastest Graphics Accelerator for your Mac” in 1999. This is the best version of ProFormance 3 with 300 MHz pixel frequency and 32 MB SGRAM (PNGA94-5).
My Philips CDI605T/20 needed repairs before I can fully use it. Some of them was mandatory for operation (TimeKeeper), some of them to make it easier on the ears (fan, optical disc drive tray). I already had experience with a Mini MMC chassis on the very similar consumer player CDI220/00 and knew what awaited me inside (its service manual helped a bit). It is actually possible to perform these repairs without taking the entire case apart (see shortcuts). I took special precautions and made photos of each and every step to be able to put everything back together in the end.
I began with removing the case and the bezels of the extension cards on the rear. Make sure to slide out the lower card first, otherwise its metal plate will grind on the solder side of the upper card.
The PC Engine flash cart by Neo Team was first released in 2006, ten years before the Turbo EverDrive was born. In 2009, they added a save feature and released it as the new version V1.1 or ‘128+SAVE’. There is no unique name of this cart because there were usually expressions like ‘power’, ‘super’ or ‘ultra’ added to the name. I bought this cart in 2011 but didn’t use it very often. It just wasn’t as compatible as it claimed to be. With the advent of 64-bit Windows 8, driver troubles limited the usability even further. And I never got the save feature to work. The whole package was sitting on my shelf until last year when I took it out again to compare it with the Super SD System 3.
This was an unplanned project. When I bought my first EBG disc for the Sega Saturn Electronic Book Operator, a Sony DD-1EX Data Discman came along with it. As it didn’t turn on, I took a closer look and found leaking capacitors and some stowaways.
After I had my first MVS at home, it didn’t take long until more arcade hardware followed. For example this CPS2. It looks shabby and needs some work, but it already has a Darksoft CPS2 Multi Kit installed.
When I bought a second-hand Sega Pico in 2015, I immediatly noticed that something must be wrong with it. I didn’t expect a lot of interactivity or gameplay, but at least it should let me draw something. It turned out that the pen was registering the position/movement and also made a clicking noise when pressed down, but nothing else happened. The error was quickly found and repaired (broken micro switch), but the photos have been waiting on my hard drive ever since. A short repair instruction was posted on the ASSEMblergames board in the following year, so I didn’t see the need to rush out an article. Well, here we go:
The label of the pen is missing and it seems that somebody tried to open it up before me:
