Restauration Works

  • Cleaned the case and keyboard.
  • Original PSU (Mitsumi SR98) replaced with MeanWell RD-35A. New mains wires from switch to PSU. New ground wire from case to PSU.
  • Replaced all electrolytic capacitors with Vishay and Panasonic ones. One bi-polar axial cap was replaced with a radial one because I couldn’t find an axial replacement.
  • Added four sockets for the ROM area.
  • Opened holes to solder in a socket for a Blitter chip.
  • Replaced original floppy disk with GOEX disk drive emulator.

Known Issues

  • PLCC socket for the blitter needs to be soldered in. Maybe I will also add a Blitter chip if I should find a cheap one.

History

    • Replaced power cable. It is soldered to the mainboard. Unfortunately I damaged one pad while preparing the board for the new cable.
    • Fixed the OLED display to the case top. The ribbon cable is hot-glued inside, so it will sit tight.
    • Plugged an USBee to the expansion connector.
    • Restauration is now completed.
