Amstrad MM12 Monochrome Monitor

This was the amber monochrome monitor sold together with the CPC464plus/CPC6128plus computers. It was also available as an option to the GX4000 video console.

As the disk drive of the CPC6128plus didn't needed 12V anymore, the monitor provided a 5V power supply only. Unlike the precedessors GT64/GT65 it also had built-in stereo speakers and thus a different connector for the signals. It can therefore not be used for the classic CPCs without adaptor cable.

Technical Specs.

Tube diameter: 30.5cm/12"
Visible diameter:  ??cm/??"
Input voltage: 220V~/50Hz
Power consumption: 42W / 0.22A
Output voltage: 5V 2.4A


The MM12 accepts a luminance, sync and ground signal in a similar way to the GT64/GT65. It also has inputs for stereo sound. The luminance is generated by combining the R,G,B signals from the Gate-Array or ASIC using resistors. The range seems to be 0V-5V.

Notes

Not to be confused with the Schneider monitor with the same model name, as that one was the Hercules Monochrome monitor for the Schneider EuroPC and similar!
