Puhui T-962 IR Reflow Oven Modifications

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.

Pippin Atmark Wireless Controller Set

This is a new member of my Pippin collection: The Atmark Wireless Controller Set (BDE-82014 / PA-82014). It has the same functionality of the standard AppleJack controller, except that it is wireless. Three infrared LEDs send the signals to a receiver. The set is advertised as compatible with both Pippin Atmark and Macintosh computers. The latter require a P-ADB to ADB adapter and the AppleJack system extension (not included).

NEC PC-FX Mouse (FX-MOU) Repair

When taking new screenshots for my old PC-FX articles, 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).

Philips CDI660 Mono IV NVRAM and 60 Hz Modification

The CDI660/00 is one of the last professional CD-i players by Philips. The mainboard, Mono IV, is also used in various consumer players. So far, there are no tutorials for 60 Hz modification. When this topic came up in the community on The world of CD-i, I looked it up in the CDI220/80 service manual (also Mono IV, with plenty of remarks for other player models) and attempted the modification myself. It has been on my to-do list for quite some years now.
First, we need full access to mainboard. Remove the marked screw of the DVC plastic holder.

Capcom CPS2 Digital AV and I/O Interfaces

After finishing the repairs on my CPS2 in April, I had already some more additions in mind:

I had already ordered the digital AV interface kit from VideoGamePerfection.com in the beginning of the year and was only waiting for the I/O interface to get started. Last month, it finally arrived. Also on the picture: a home-made kick harness and a RG174 coaxial cable.

Pippin Atmark PA-82001-S External SCSI and ROM Dump

Earlier this month, I wrote about my Pippin Atmark PA-82001-S Monitoring Unit. Initially, I didn’t plan to do any modifications to this special Pippin model. But then Keith Kaisershot told me that it is possible to feed a long SCSI cable over the metal lips of the case without doing any permanent modification. He also asked me to verify the checksum of the ROM. In this article, I will add external SCSI to my Pippin and also dump the ROM.

Pippin Atmark AppleJack Controller

Pippin consoles are based on Apple Macintosh PowerPCs. It is only natural that they use serial Apple Desktop Bus devices. There is a major difference though: the proprietary child proof AppleJack (P-ADB) connector. I never bothered to find an adapter dongle and was stuck with a Pippin Atmark AppleJack controller that wasn’t able to reliably register trackball movements anymore. Unfortunately, the ball is held in place by a plastic ring with two tiny holes. There’s probably a tool to open it up which I don’t possess. I decided to open up the whole controller from the back to clean it and also to take pictures. Note the nice red rubber cap that came with my controller.

Pippin Atmark PA-82001-S Monitoring Unit

Back in 2010, I was aiming to own every game console system that used optical media, the Apple Pippin was one of them. I was lucky to obtain a lot of Bandai Pippin Atmark PA-82001 consoles from Japan for a reasonable price. Upon closer inspection, I noticed that one of them was different: It had the model number PA-82001-S, a pre-release ROM and several areas shielded with copper foil tape. No one has documented this model yet on the various Pippin websites. The only trace that I can find on the internet is my unit and another one that has been offered on Yahoo auctions earlier this year. Forum members of Assemblergames assume that this is an FCC model for evaluation / EMC accreditation.

I will call it “Monitoring Unit” because it came with an AP2735-01 KINKA non-E pre-release/monitoring ROM. On this Pippin FANDOM page, it says: “A WORM version of the same [Golden Master] ROM was manufactured in small quantities for market testing of ‘Monitoring’ units.” On the same page and also here it is mentioned that only 500 of these ROMs were released.

Terraonion MegaSD Cartridge

This has just arrived yesterday: The Terraonion MegaSD Cartridge. The makers are known for quality products like the NeoSD and the Super SD System 3. Their recent move of the office from Spain to Andorra has stirred some controversy and caused over-the-top reactions from some buyers. I didn’t experience any trouble and my cartridge arrived safely within a few days. This is what I got:

Philips CDI605T Disassembly and Repair

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.
