"What we have today is an EML 500 Synthesizer. In the late seventies, there were a few different US based synthesizers. You all know about Moogs, Arps, EMS, Oberheims and all of the Japanese models, but EML made unique and idiosyncratic designs.
This is their 500 model, designed as a competitor for the Minimoog/Micromoog and the Arp Odyssey. In its case, it didn’t make much a ripple in the pond, but some guys from Akron liked it. Devo had a EML500 in their studio, and that should tell you all you need to know about this guy.
These are extremely rare. It is probably a Good instrument, but for this model, there aren’t a lot of choices."

Custom Korg Poly-800 with Filter and Chorus Mods
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
"This thing is great for dreamy evolving pads, drunk sounding horns, lofi surfing, and 80’s car chases.
The filter is modded to allow free playable control over cutoff and resonance, with a 2 pole/ 4 pole switch installed for more variety.
The chorus has been modded to allow adjustment of the rate, going into audio range for ringmod-like effects, adjustment of depth, and a true mix knob allowing for control between fully dry and fully wet.
There’s an external input, so you can run some audio signals in and override the noise.
The internal battery has been replaced with a battery clip for no-solder battery swaps and a brand new battery has been installed.
All the tact switches have been replaced, so no annoying switch bounces while trying to program a sound.
The instrument is painted to match the green lettering in the programmer menu."

Roland GR-500 Guitar Synthesizer with GS-500 Guitar and 24 pin cable
Note: links to listings are affiliate links for which the site may be compensated.
via this auction
Two pics of the of the GR-500 inside below.
""Listed here is the flagship of the legendary pre-MIDI, all analog guitar synthesizer systems; The Roland GR-500 synth and GS-500 guitar.
This listing includes the Roland GS-500 guitar controller, The Roland GR-500 Synth module and a factory 24pin cable.
The GS-500 guitar is in Very Good condiction with all of it's original electronics, including the hexaphonic pickup, synth controls and 24pin connection to the GR-500 synth module. The gutiar hasn't been modified at all (as far as I can tell). The original pickups are intact as are the string isolators which are essential for the mulichannel infinate sustain system to fucntion. There are a few -very- small scrapes and dents as one might expect from a guitar from 1978... but overall it looks like this insturment wasn't used heavily and it looks great.
The GR-500 synth itself has recently been serviced (2023). It just got entirely re-capped (capacitors replaced)s, power supploy serviced, and several of the chips were changed from soldered to socketed.
Almost all of the features of the synth work well. The Guitar, PolyEnseamble and Bass sections work exactly as you'd expect them to. The PolyEnsemble and Bass sections are remarkably cool. Being able to play fully polyphonic chords on an anlog guitar synth is just a beautiful thing.
The Solo Melody section, however, is currently not functioning quite correctly. Right now the pitch of the Solo Melody section does not track the pitch of the guitar correctly, and the amplitude detection in this section doesn't seem to be tracking correclty either. I am not sure what the issue is, but two techs have suggested that this section may just need to be properly calibrated and the instructions for this procedure can be found in the service manual which is readily available. I regret not having the time in my life right now to address this issue as it may be quite minor, but I just can't say what this issue is for sure and I wanted to be totally up front that this issue exists.
So we have this remarkably, unique and rare set of GR-500 and GS-500 where the gutiar is in really nice shape, and the syth has recently been serviced and cleaned, but does have some issues with the Solo Melody section."

Introducing ALM MEGA MILTON - Compact Utilities
video upload by ALM TV
"The 'MEGA MILTON' is a smorgasbord of handy all analog utilities in just 8HP that will greatly extend the functionality of your Eurorack system.
It includes a stereo line input converter for incorporating line level external sources into a Eurorack system, a fixed 4 input mixer with breakout attenuator for combining signals, a gated slew limiter for adding slides to sequences, a sample and hold with analog white noise with a myriad of uses such as generative melodies or producing percussive textures and finally a buffered mult for droop free signal distribution with handy LEDs to monitor.
All sections are normalised to help with typical use cases such as generating random CV from the sample & hold section, a smooth random source from the slew output and breaking out a standalone attenuator from the fourth mixer input.
The 'MEGA MILTON' provides essential classic synthesizer building blocks for patching in any Eurorack system. In this video we take a look at all of its features."
