Roland PG-200 Programmer for JX-3P, MKS 30 w/ Cable

via this auction

"The PG-200 is a programmer for the JX-3P and the MKS-30. Since those instruments were some of the first from Roland to come out with digital parameter access for editing, as opposed to sliders and knobs, Roland made the PG-200 available. The PG-200 also works with Roland's GR-700 Guitar Synth."

Roland SH-101 with Case, Mod Grip and Strap

via this auction
"# 32 key, monophonic analog synthesizer.
# One oscillator with 3 simultaneous waveforms, an 'octave-divided' square sub-oscillator, triangle, and square/pwm waveform.
# 100 step sequencer
# Low-pass filter/VCF capable of self oscillation. The self oscillation filter can be used to make fat bass sounds.
# The controls are simple to use as there is a slider or switch available for every single parameter

# External trigger input to control the speed of the sequencer or the arpeggiator.
# The LFO is super fast and can be used to make fast arpeggios with decay down to zero volume, without retriggering the ADSR.
# External control is achieved using CV/Gate
# The popularity of the SH-101 is such that many companies have seen fit to cater to a significant market of musicians who want the sound of the 101 but are not able to pay for one. This has led to a rise in clones—devices designed to emulate the SH-101 for a much cheaper price."

Kawai K5m Synthesizer Module

"*The backlight is out, though I have used it as such for years. It will not be readable in the dark, though is fine in a lighted room. Replacement backlights are available on-line, and usually go for about $30 on ebay."

I did a quick search and found this site that sells a number of LCD screen replacements for various synths. I did a search here on MATRIXSYNTH and only found this post on a K5m with a replaced screen.
