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.

First Steps in OS-9 on Philips CDI605T

The Philips CDI605T/20 is the last professional CD-i player with authoring / development capabilities. As every other CD-i player, it runs on CD-RTOS v1.1, a real-time operating system based on Microware OS-9/68K v2.4. Additionally, it features extended memory, an internal OS-9 shell, a floppy disk drive, SCSI, ethernet, RS-232C and printer ports. When compared to its predecessor CDI605/00, it was upgraded with a tray loading mechanism, a built-in DVC and a newer system ROM v1.3. Even though this player is perfectly fine for playing the whole range of consumer CD-i titles, I got it mainly for experimenting with the titles and the operating system. On the first start, it performed a CRC check and displayed the software version:
