Specs : 

The Yamaha DX100 is an FM synthesizer released by Yamaha in 1986.[4][5][6]  It offers four operators for each of its eight voices, and has eight algorithms (compared to the DX7's  six operators for each of its sixteen voices, and thirty-two  algorithms). It has only 49 mini-keys, and no arpeggiator or effects,  but is still useful, known in particular for its bass patch #1. It  features up to 192 presets, seriously improving the DX7's limited preset  capabilities. It can also store 24 user-programmable sounds in RAM. It  lacks cartridge support, but voice patches can be saved to and loaded  from an external cassette recorder. 

It was the cheapest user-programmable FM synthesiser made in the  1980s, leading to its popularity even amongst professional musicians in  the 80s and 90s.  It's essentially a cut down version of the DX21 and DX27, using the same FM chip, the YM2164.
