Sound devices

I have a special interest in computers and peripherals from the 80`s. I love the distinctive sound from the chips from this era, and the design of the casings. Here is a collection of some of the devices I have built.

Atari cases

YM2Yamaha YM2149 chip synth cased in an ATARI mouse. It has stereo out from the RCA plugs, and MIDI through the USB plug. I got the mini synth from Wil Lindsay’s Stray Technologies and fitted it in the mouse I had from an old broke ST.

ST3MIDI-keyboard cased in an old ATARI 1040 STf case. 25 keys, 8 knobs, 10 buttons, 1 slider, pitch bend and modulation. In addition to the 10 assignable buttons, the octave up and down are mapped to the original numeric keyboard on the right. Original LED and on/off switch. Works great with the YM MIDI synth.

Here is a simple test of the keyboard and synth module, expect no musical wizardry :)
