However it is mandatory to check that the cableĬonnected to the Atari Midi Out does not have any wires connected to pin 1 & 3. It is possible to use standard Midi cables for the Midi In and the Midi OutĬonnection to/from the Atari. In connector there is no shield which is standard midi. It is therefore recommanded to use cable without shield connection. That a shield is connected on the Midi Out connector which is not following the midi standard.
The Atari has two midi DIN5 connectors: A standard Midi In connector, and a non standard Midi Out connector that also includes the Midi thru output (this wasĭone to avoid adding a third connector as specified in the standard midi) 1 This allows to have a midi thru interface without the cost of an extra connector. Note the unconventional connection of Midi Thru signals to pin 1 & 3 of the out midi connector. The Atari interfaces midi through a dedicatedĦ850 ACIA (Asynchronous Communication Interface Adapter) chip as shown on the right. It uses asynchronous signals (8 bits plus start and stopīits) at 31250 bauds (bit/sec). The midi interface is used to connect the Atari to electronic musical On the back panel you find connectors for a modem, printer,
On the right underside contains the connectors for the Mouse & Joysticks
On the left side you find connectors for the midi in and out, and a cartridge Important note: On this page the connectors pinout are always given looking at themįrom the front side and not from the solder side. It also provides information on some standard cables andĬonnectors not specific but useful for the Atari ST. Interfaces of the Atari ST and the associated connectorsĪnd cables.
This page gives information on the numerous DB15 - DB9 (CGA/EGA type) Adaptor/Cable.
