Video

There is a RF connector and a 13-pin DIN socket that combines composite video and RGB signals. If you have a monitor that supports 15 kHz horizontal sync frequency, you can connect the 13-pin DIN socket to VGA input.

One of the unfortunate features of Atari ST is that its low/medium resolution mode (color) and high resolution mode (monochrome) are selected through a pin on its video port. So there are two separate cables needed to cover all graphics modes.

Floppy Disk Drive

The original FDDs may be worn out and refuse to read the disks. It is possible to replace them with a PC 1.44MB FDD, for example Sony MPF920. There are two things needed to make it work:

  • Changing the drive select from SEL1 to SEL0, either through jumpers (earlier models) or through a soldering fix
  • Connecting the drive data cable upside-down

Unfortunately the original front plate of the drive may not fit the new one.

Atari Forum contains a lot of detailed information on FDD replacement.

Mouse

In the absence of the original Atari mouse, it is possible to connect a USB mouse through an adapter. I purchased and recommend a TOM+ adapter, that also fits Amiga and C64/128.
