Sony DD-1EX Data Discman Repair

This was an unplanned project. When I bought my first EBG disc for the Sega Saturn Electronic Book Operator, a Sony DD-1EX Data Discman came along with it. As it didn’t turn on, I took a closer look and found leaking capacitors and some stowaways.

Bandai Datach SD Gundam: Gundam Wars Barcodes for MAME

SD Gundam: Gundam Wars (SDガンダム GUNDAM WARS) is the third game for the Bandai Datach. I bought it about four years ago and finally managed to sort and scan all the cards for the use in MAME.

This time, I also scanned the artwork, manual and a special card that wasn’t part of the original set. I’ll try to complete the previously released sets in the future as well:
Ultraman Club: Spokon Fight!!
Dragon Ball Z: Gekitō Tenkaichi Budokai

Capcom CPS2 at Home

After I had my first MVS at home, it didn’t take long until more arcade hardware followed. For example this CPS2. It looks shabby and needs some work, but it already has a Darksoft CPS2 Multi Kit installed.

Sega Pico Pen Repair

When I bought a second-hand Sega Pico in 2015, I immediatly noticed that something must be wrong with it. I didn’t expect a lot of interactivity or gameplay, but at least it should let me draw something. It turned out that the pen was registering the position/movement and also made a clicking noise when pressed down, but nothing else happened. The error was quickly found and repaired (broken micro switch), but the photos have been waiting on my hard drive ever since. A short repair instruction was posted on the ASSEMblergames board in the following year, so I didn’t see the need to rush out an article. Well, here we go:

The label of the pen is missing and it seems that somebody tried to open it up before me:

Bandai Datach Ultraman Club: Spokon Fight!! Barcodes for MAME

Five years ago, I bought my second game for the Bandai Datach: Ultraman Club: Spokon Fight!! (ウルトラマン倶楽部 スポ根ファイト!!). Also five years ago, it became possible to play the Bandai Datach games in MESS and make use of scanned barcodes.

In the meantime, MESS became MAME, and it is still possible to play these games (for instructions see below). It’s time for another batch of scanned cards.

SD2SNES Mk.III / SD2SNES Pro

This has arrived today from Ukraine: The new SD2SNES Mk.III aka SD2SNES Pro, designed by ikari_01 and manufactured by Krikzz.

Right now, it seems to have a bug when used in combination with a SuperCIC. As soon as the SuperCIC is enabled in the configuration, there is no picture and sync is lost (also, weird readings on the OSSC display). Upon switching the frequency, the LED of the console turns red and is stuck in that status. According to this thread, a firmware update is needed for one of the SuperCIC chips. I’m looking forward to see if this can be resolved through a SD2SNES firmware update. Otherwise, I’ll have to desolder and flash one of the SuperCIC chips.

IBM ThinkPad 760 Series MIDI/Game Port Adapter

While doing my research for another project (finding a plug for the Philips CDI350 RGB in/out port), I came across an old IBM MIDI/Game port adapter. It is listed with P/N 29H9467 (FRU P/N 29H9269) and can be used with some models of the ThinkPad 760 series (760CD, 760ED, 760XD, and also 765D). What makes it so special is the plug. It is similar to the 26-pin external floppy connectors used by several laptop brands in the ’90s. While most of the external floppy drives used a 17 mm wide plug, this one is 20 mm wide. This JAE datasheet lists the plug as TX20A series connector, part number TX20A-26PH1-D2P1-D1.
