FM TOWNS II Fresh・E Battery Replacement

When my FM TOWNS II Fresh・E suddenly refused to boot from HDD and Towns OS (from CD) didn’t show the HDD anymore, my first thoughts were that the HDD has finally given up. It sounded like an airplane engine lately (and still does). Then I noticed that date/time settings were lost too, so it was probably related to the BIOS battery. To access or replace the battery (3V CR2450) the whole unit needs to be disassembled.

Atari Jaguar Power/Sound Fix and Rotary Controller

The other day I prepared my Atari Jaguar to build a rotary controller for Tempest 2000. I hadn’t used it in a while and accidently picked the wrong power supply – smoke was rising immediately from the console.

The culprit was easily found, chip U38 (MC34163DW):

Philips CDI 220 Mini MMC 60Hz Modification and TimeKeeper Replacement

Recently I found a CDI 220/00 with Mini MMC mainboard. It’s a heavy and bulky unit that contains lot of PCBs, wires, screws and metal parts. It’s one of the first consumer CD-i players, later models have all components on one single mainboard (Mono).

NEC PC-FX Laser Pickup HOP-E1

I’ve been struggling with a weak PC-FX laser for quite some time. What kept me from changing the laser or pickup unit was that having to take apart (and put it together later) the PC-FX is something you wouldn’t wish your worst enemy. However, getting close to the drive unit is surprisingly easy, just follow this guide.

First you need a replacement laser. I chose the complete pickup unit (Hitachi HOP-E1), it’s available for about 15€.

Repair a Xbox 360 Controller

If you drop a Xbox 360 controller don’t let it land on it’s bumper buttons. The micro-switches break easily in the inside. They might still work but need more pressure to be triggered. This problem plagues old Sega Saturn gamepads too.

To open Xbox 360 controllers you need a special Torx security screwdriver with a hole in the tip, size T8H. If you don’t have this rather unusual screwdriver you can break the tiny pins in the screws and unscrew them with a regular T8 or T9 Torx screwdriver. Seven screws need to be removed (yellow circles). One of them is hidden behind the white sticker with the barcode and not behind the black sticker where I looked for it first (red circle).
