In 2014, I bought two top-loading CD-i players, the Philips CDI550 and CDI450. While the Magnavox CDI550 pops up every now and then in the U.S., the Philips CDI550 is quite rare in Europe and I’ve only seen a single one in all these years.
It’s been a while since I opened my first Philips CDI350 portable CD-i player and published a repair guide with capacitor list. I have already received some positive feedback that this was helpful for others fixing their players. However, part 2 of the article ended with a big question mark because some topics remained unsolved. Let’s have a look at the status of these topics and see if I can resolve them today in Philips CDI350 Repair Part 3.
This turned out to be my fault. After carefully following the traces to and from the video encoder and comparing every component with the service manual, I noticed that I had soldered two electrolytic capacitors with the wrong polarity: C938 and C991. I can only assume that this happened because I used the + marks as indicators and not the white dots. Just look at the vast amount of plusses:
Continue reading Philips CDI350 Repair Part 3The Bandai Pippin Atmark Floppy Unit PA-82002 is an expansion dock for the Pippin consoles that made it past the prototype stage. It was released on the Japanese market together with the Pippin Atmark in 1996. It is still incredible rare and it took me while to get a hold of one of these units. The functionality is the same that the replica floppy adapter provides and the main reason why I bought it is really the casing. The floppy adapter setup was too unpractical and fragile and I was looking for something sturdier that could stay attached to the console at all times.
This article is mainly about photos and taking it apart. There will be a small section with explanations at the end.

The other option, CD-i Link, and how to connect a Philips CD-i player to a modern Windows PC is covered in the first part. Make sure to follow the guide to set up the connection and the terminal program Tera Term.
CD-interlink (alternate spelling: CD-i’nterlink, CD-Interlink and CD-InterLink) is a program developed by Novaré International (and human interaction inc.) in 1994. It is dubbed The Complete CD-i File Manager and has some useful functions to view and manipulate single/multiple files in the NVRAM. Some functions require the connection to a terminal. At first sight, it seems to be easier to use for beginners because it has a graphical user interface that can be operated with a CD-i controller. Don’t get fooled by this though, because file transfers are actually more complicated to set up than with cdilink.

I will cover the other option CD-interlink in the next article.
Back then, I built a null-modem cable which I still use today. Over the years, I’ve used it to connect all my CD-i players with PCs and portable devices to transfer data and for debugging purposes. The cable was built according to the CD-i Nullmodem Cable Specification with a Mini-DIN-8 and a DE-9F connector and works with most of the CD-i players. Some players require additional adapters and/or different connectors: Top-loading players with only one port (e.g. CDI450) require a port splitter; professional CDI60x players require a cable with DE-9F connectors on both ends while LG/DVS players require a cable with a DE-9F and a DB-25F connector. You can find most of the usage scenarios and additional cable and adapters that I’ve built in the CD-i Archives.

The new firmware enables changing the output resolution with the Volume – and + buttons. The current functions of these buttons (scanlines and vertical offset adjustment) have been removed.
When I installed the AV interface last year, I wasn’t very happy about the 8 missing lines in the default 1920×1080 resolution. I was hoping to have a 1920×1200 Line5x format one day, similar to the OSSC. This is now reality: By pressing Volume +, I can change this video output to this format.
Update (2020-10-23): A new firmware with an OSD and more settings and features has been released.
Continue reading Capcom CPS2 Digital AV Interface Firmware UpdateThe 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.
Continue reading Puhui T-962 IR Reflow Oven ModificationsThis 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).
50/60 Hz modifications are quite simple hacks that have been figured out for almost all Philips CD-i player types with SCART connector. But what about all the CD-i players that do not have an RGB output, either because of reduced cost or because they have been sold outside of Europe? Technically, they can still be modified, but the foreign mode is pretty useless and results in a black and white picture or no picture at all.
The reason is easily explained: All Philips CD-i players have a main system clock at either 30,0000 MHz (PAL) or 30,2098 MHz (NTSC) and additional clock generators for some components. All newer players (Mono III and up) have a Brooktree video encoder and generate the colour subcarrier frequencies (PAL 4,4336 MHz and NTSC 3,5795 MHz) from the system clock. The older players with a Sony video encoder use one or two additional crystals and some more components for this task.
Continue reading Philips CDI470 PAL/NTSC ModificationIf your CD-i player’s clock is way off, then you can try to make use of the Timekeeper clock calibration tool of the low-level test. Be aware that it needs an accurate frequency counter and won’t help if your Timekeeper suffers from an empty battery.
Here are some NVRAM+RTC solutions. The 8 KB chips operate within the accuracy of ± 1,53 minutes per month at 25 °C (and the 32 KB socket better than ± 1 minute per month).
8 KB – ST MK48T08B and M48T08 Timerkeeper.
8 KB – Dallas/Maxim DS1643 NV Timekeeping RAM.
32 KB – Dallas/Maxim DS1216C SmartWatch RAM (with Mitsubishi M5M5256DP SRAM).
