"A Roland MC-202 monophonic synth/sequencer, unmodified and in completely original condition. One owner, bought about 1983, very little use, stored for most of its life. Comes with a non-standard power supply plug pack (9VDC 300mA) with an Australian plug. Everything appears to work: all synthesiser functions and controls work, all pots and sliders are smooth and not noisy, both LEDs and the internal beeper work, all keys function reliably. All sequencer and programming functions also appear to work. Did not test saving and restoring from cassette tape, nor DIN-sync, but no reason to think they would not work.

Please note the following carefully:
there is a small crack at the lower left corner of the case (see photo), but it is very minor
there is a very small amount of corrosion on the battery contact in the battery compartment (see photo), but there has been no battery leakage.
there is a dark patch at the upper left of the LCD - see photos, including photo with the unit powered off showing the dark patch. The dark patch does not obscure any information in the LCD display.
the LCD has very poor contrast when seen from directly above. When viewed from about 45 degrees (which is the normal working angle) it is perfectly legible (see photos)
some of the segments in the LCD display flicker slightly from time-to-time.
It is possible that the LCD is beginning to fail. However, it remains 100% usable as it is - the LCD is completely legible. The LCD unit is replaceable (see page 3 of the service manual available at http://www.dinsync.info/2010/02/roland-mc-202-service-manual.html ), it is not soldered to the PCB and can be readily replaced if a new LCD to suit can be obtained. Alternatively, this MC-202 would be perfect for the popular and well-documented CV and gate external jack modifications which bypass the sequencer CPU, if you just want to use the synth engine (which sounds great), or as a donor for spare parts to keep other MC-202s going.
