Chroma Polaris Membrane Replacement Instructions

Full details with tons of pics on the excellent Rhodes Chroma website here.

"This describes the replacement of the Chroma Polaris membrane switch assemblies. The process is not terribly difficult, but great care should be taken, because the adhesives are quite sticky, and if the panels are accidentally misaligned, it is unlikely that they can be lifted and realigned without damaging them. We cannot be responsible for your installation errors, so get it right the first time."

Wayfar MidiNES

via this auction

"This is a rare MidiNES cartridge made by Wayfar, a.k.a. x|k. MidiNES is a cartridge that offers robust MIDI control of the Nintendo Entertainment System's internal 5-channel synthesizer - a serious chiptune tool, or just a great way to get iconic Nintendo sounds! Here are the 5 channels:

2 square waves
triangle wave (the iconic NES bass sound)
noise (great for percussion)
DPCM sample playback, preloaded with classic drum samples

MidiNES is extremely difficult to find. It is difficult to buy them from Wayfar due to an extended waiting list, and they appear on eBay only rarely. This one is in excellent physical shape, and perfect working order.
It will ship in an anti-static bag inside a padded box, and will come with a Nintendo cartridge sleeve, which is not pictured. No manual is included - all the documentation is primarily kept online at Wayfar's site."

Signed Future Retro Revolution Analog Synthesizer Sequencer

via this auction

"Mint condition future retro revolution. It has the classic sweet///wooden sides\\\ and is such fun synth/sequencer. Very easy to use and intuitive. It has a filter input for a sweet effect. You can even use the sequencer to modify the filter in and together with the cv mod knob..it can kind of sounds like a moog MURF effect. The distortion is superb and 100% analog! Oh yeah and the digital effects are a sweet surprise... Especially the hall reverbs. The revolution can sound like a tb-303 and then some!!! Plus it has midi, din sync, voltage outputs... So it's very versatile! These are pretty rare and this one is signed by Jared of future retro."
