The production number on the label contains the year and calendar week (example: 1A 00 9447). This applies to almost all Philips CD-i players and accessories. So far, only the white mice for the professional players didn’t follow the year code. A full production number has 8 or 9 digits and an additional 5-6-digit serial number at the end. But most accessories are only labelled with simple 8-digit production numbers and that’s why you find so many accessories with the very same data on the labels.
The PC Card Drive HPC-301 is still the only way to read and write Atari Portfolio memory (Bee) cards on a PC. Make that an old PC with an ISA slot for the interface card and DOS. The driver can be found here and here. In the PofoWiki (German), there’s more information about its usage and what needs to be considered when you have Windows 9x. For me, the DOS mode worked fine and I had less trouble accessing the card reader after loading the driver without parameters, e.g. DEVICE=C:\CD.SYS.
There seems to be another way to access the card drive: A software called Portfolio RAM-Card Reader by Digital Data Deicke (now Pentagon GmbH) is mentioned in the Atari-Home.DE forums here and here. It is reported to work even under Windows XP via Direct I/O.
Today, we’re only going to have a look at the hardware. Just look at this massive cable with 37-pin D-sub connectors that connects the card drive with the interface card:
While the Amiga CD³² can play CD-MIDI discs, it lacks a MIDI out port to hand over the data to a MIDI playback device. I’m going to build an adapter with a keyboard pass-through for its AUX port.
CD-MIDI (or CD+MIDI) is an extension of the Red Book Audio CD that allows MIDI data to be stored in the subcode channels, just like CD+G and CD-Text does it with graphics and text data. Only very few devices are known to be able to make use of that information: CD³², CDTV and WonderMega. Even though the Green Book describes a MIDI extension, the Philips CD-i is not among these devices, and so far, no CD-i hardware or software that made use of MIDI has surfaced.
When looking for an affordable and reasonably accurate device to measure the (standby) power consumption of old power supplies, I came across the ELV EA 8000 Energy Analyzer. It’s being sold as complete device or as a kit; I went for the kit to spend some time with it and have a better look inside.
It has two power measuring ranges (40 and 3680 VA), several measuring functions (e.g., active / reactive / complex power, power factor, costs), storage space for 10 devices and up to three different electricity tariffs. Before buying, I was already aware that it has some flaws, but more about that after the assembly.
A quick and dirty hack to save a broken Philips CD-i RC6 remote control with a Sega Mega Drive controller.
Most CD-i players come with or are compatible with the 22ER9055 CD-i Commander, an RC6 remote control with a pressure-sensitive thumbpad. There are three known versions of the CD-i Commander:
RV 7701 – standard remote for most CD-i Players.
RV 7704 – with additional stand-by button for CDI660 and 670.
RV 7706 – with additional controls for CDI740.
When buying a used remote control, your first action should be to check the battery compartment for obvious leaking damage and also take it apart to find hidden damage. You never know if there were accidents in the past and previous owners just cleaned out the battery compartment without looking further into it.
The Bandai Playdia Quick Interactive System (Q.I.S) was a short-lived console (1994-1996) that was released in Japan only with an unusual library.
In 2009, one year before I had my first Pippin, I bought two Playdia consoles with a few titles. One Playdia was sitting in the corner of my room all these years, almost unnoticeable because it is so compact and small. Recently, it caught my attention again and I was wondering why I never wrote an article about it. Well, here it is: I disassembled it, took photos and played many titles to find something interesting.
All titles start with the Q.I.S logo which is (most of the time) followed by a jumping Bandai logo.
Replacing blown fuses in Philips CD-i players with Mono III and Mono IV mainboards – sounds too simple to write an article about. That’s why I’m going to dig a bit deeper into the topic. An important fuse sits on the mainboard and protects the -5 V rail. I tripped (over) it by accident and was confronted with these weird symptoms that are hard to diagnose:
No video output (well, there is something, but see below)
Service Shell video output with a rolling/flickering image
The disc tray opens on its own (tray loader motor is constantly spinning)
These two foul language filters have been in my possession for quite some time. I bought the TVGuardian 101 in 2014 as alternative to a Closed Captioning decoder to view subtitles of some NTSC LaserDiscs. In 2015, I got a Pioneer DVL-909 LaserDisc player with S-Video output together with the newer TVGuardian 201, which supports both composite and S-Video. I never got around to write an article about it, but now it’s time to remove that from my to-do list.
After 2,5 years, TeamEurope updated their Sega Pico Flash Cart / Adapter to v2. Previously, I either modified“Assembled in Mexico” Pico cartridges or used the first version of the flash cart / adapter. Version 2 comes with some new features (e.g., added switches for ROM sizes and memory banks) and is split into two PCBs: FULL and REPRO. Additionally, they have released design files for the back covers.
In this article, I’ll upgrade a Philips CDI450 with 32 KB NVRAM. You’ll find all information that is needed to modify the system ROM and the mainboard. If this sounds familiar – yes, it does: In 2019, I explored the possibility to upgrade a CDI470. Even though patching the system ROM failed back then, the experiment was still a success. The final solution to access 32 KB NVRAM was to use the ROM of a 490. As it turned out later, this was also Philips’ solution for the 470/85 model, but that is a topic for another article.
With the 450 (and all other top-loading players with Roboco mainboard) it is a bit different: It’s a low-cost model with 8 KB NVRAM only. The mainboard was neither prepared for a bigger NVRAM solution nor is there a similar advanced model that I could borrow the system ROM from. This time, a ROM patch must succeed.
