A spontaneous article about the NEC PC-FXGA: The PC-FX Game Accelerator Board for PC-98 and DOS/V. It emerged from the search for a replacement breakout box for the PC-FXGA DOS/V card in the PC-FX Fan Club Discord server. The details of the breakout box are in the second half of the article, and before that some information and photos.
There are already many resources about PC-FX(GA) (see list at the end of this article), so I won’t go into too much detail here. Basically, it’s a PC-FX on a card for your PC, with a special feature. Game Accelerator means that it also contains the 3D chip Huc6273 (Aurora) that is not present in the normal PC-FX. There are two versions of these cards: PC-FXGA, a C-Bus card for use with NEC PC-9800 series computers and PC-FXGA DOS/V, an ISA card for use with IBM PC-compatible computers running DOS/V.
Last week, I just wanted to quickly test some Famicom carts and realised that the console wasn’t outputting any picture or sound. There was still a reaction on the TV though: black picture and a crackling sound when I switched it off. Fearing the worst, I opened it up and saw my favourite insulation tape. However, as I’ve learned in the past, this stuff disintegrates over the years and sticks to everything, so now I was apparently in for not only a repair but also a clean. I opened the console and plugged it in again. When I removed some of the insulating tape, graphics rubbish suddenly appeared on the TV. On closer inspection, I realised that the NESRGB board was tilted slightly backwards. It must have come loose at some point.
The DVS VE-200 CD-Interactive Player is a CD-i player manufactured by LG. Like other CD-i players, it contains a battery-backed NVRAM and real-time clock. In this article, I will take a look inside and show how the battery can be replaced while making sure that the NVRAM data won’t get lost in the process.
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:
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.
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.
