“The power supply is bad and needs replacing. I’m not sure if anything else is wrong, everything looks fine but so did the power supply. If you are great at fixing synths then you get a really great synth at a great price. I even have the original 40 year old box and may have the original manual. The system 100s have a really great classic sound. I think they are underrated.

” Verkaufe hier einen Klassiker der 70-80er Jahre, das Roland System 100, Modul 101.
Semi modularer Synthesizer mit genialem Klang. Da ich leider nicht alle Funktionen bis in´s Detail testen kann, verkaufe ich
Ihn sicherheitshalber als defekt. Das Gerät ist über 30 Jahre alt.
Klang ist jedoch soweit ich das beurteilen normal justierbar. Oscillator dank 440hz Funktion einwandfrei stimmbar.

“Roland system 100 model 101 this auction is just for the portion pictured I do not have the additional patch bay. unit was shop cleaned and tested by a local synth and keyboard repairman.” Link
“Roland system 102 expander super rare modular synth piece from the 70′s. I love these units but I’m not using it much anymore, has the most raw sound of anything roland ever produced. This unit is in pretty good shape and the only functional flaw is that the pulse width mod switch is loose but still works. These rarely come up and are like having some crazy buchla type 70′s vibe that integrates perfectly with a modern euro rack setup. This is for the 102 expander only. It’s not us voltage so a converter is included.” Link
“Up for sale is the classic ROLAND System 100 Model 101 vintage analog synthesizer.
The unit appears to be working reasonably well, all the keys and sliders and knobs worked fine to the best of my knowledge. There is quiet a bit of noise on the sliders and switches, which could probably do with some adjustment/servicing done. Most notably, the VCO ADSR slider only allows output if you move right up to above around 8.
Cosmetically, its in reasonable condition for its age I suppose. There are some wear marks and scuffs here and there, with a sticker mark on the back and few slightly bent sliders as shown. But otherwise, all original parts seem to be there and in shape. I’m including plenty of pictures so you can see exactly how it looks.” Link
“An unmodified Roland System 100 Model 101 monophonic synthesiser in rough but mostly working condition. Manufactured around 1975, bought second-hand in about 1982, and then stored in a somewhat damp garden shed ever since. Internal 240V power supply with original Australian plug.
Please examine the photos on this listing carefully, and note the following points carefully:
completely original condition, no modifications or additions
there is a lot of rust on the exterior, including rust under the enamel of sections of the control panel, and on all other exterior metal surfaces
inside there is much less rust, just a few small patches at the rear of the case
all the circuit boards, circuit components and wiring look fine, no obvious corrosion or degradation given that it is nearly 40 years old (see photos of PCBs)
several of the keys on the keyboard do not work – the top key doesn’t trigger at all, and a few of the keys trigger the gate unreliably – the contacts probably just need cleaning
all the keys on the keyboard are intact and undamaged, and mechanically all the keys seem to work fine i.e. no broken springs or hinges
all the panel sliders (potentiometers) seem to work, although most of them are a bit stiff, and a few (filter resonance, LFO speed and portamento) seem to be a bit electrically noisy and/or jittery
all the panel rotary potentiometers work fine, although the main VCO frequency pot is very stiff (but not electrically noisy)
the VCO waveform selector switch is a bit unreliable when selecting the sawtooth waveform – it needs a wiggle to make it work sometimes
the high and low level main output sockets and the headphone socket (all of then 6.5mm) all work correctly
the 3.5mm socket modular jack points and the CV and gate input and output sockets (3.5mm) on the rear have not been tested but there is no reason to think they would not work (at worst the socket contact points may need a clean)
all sections of the synth circuitry appear to work correctly and reliably, subject to noisiness and jitter in some of the control pots noted above
no manuals or documentation, but a full set of user manuals, patch cards, and the technical service manual are available at http://fa.utfs.org/diy/roland100/
series of photos showing how to service the control sliders can be found at http://fa.utfs.org/diy/roland100/system100_restoring/
the synth probably needs re-calibration, but all the trimpots are very readily accessible on the circuit boards (see photos) and calibration instructions can be found in the service manuals.
please do not open the lid on this synth unless it is switched off and unplugged from all mains power! The mains wiring inside is original, and reflects safety standards from 40 years ago. However, both the mains and DC sides of the power supply are fully protected by fuses. Nonetheless, use of a residual current detection (RCD) power safety device when using this synth is strongly recommended.
Overall, this synth looks rough but it mostly works, and could easily be restored to perfect working condition (although cosmetically it will never look very good). Due to the many patch points which use 3.5mm jacks, the 10V p-p signal and CV ranges, and the 1V/oct CV tracking (with external CV and gate in and out jacks), it should integrate easily with modern Eurorack module synths for someone who wanted the classic Roland modular synth sound. Alternatively, it could be a donor for spare parts to keep other System 100 Model 100s (or System 100 Model 102 expander modules, which use mostly identical circuit boards) operational. ” Link
“Overall, the synth is in outstanding working condition. It has been fully tested prior to sale by my synth tech and is 100% working.
Cosmetic condition for the full set is near mint – an outstanding example:
101 keyboard: condition is near mint.The front panel is very clean and 99% free of marks, with the paintwork and printing in superb condition. There is a rectangular shadow on the paintwork on the right hand side just above the keyboard where a Roland sticker must have been fixed at some point. This is difficult to see in most lights. The side panels are excellent. The rear panel is also free of marks. The base panel is free of marks.
102 Expander module: overall condition is excellent. The front panel is very clean with the paintwork and printing in superb condition. A small mark at the bottom of the main front panel below the control area and a couple of tiny (1mm) blemishes on the front control area are all to report. The side panels are excellent. The rear panel is also free of marks. The base panel is free of marks.
103 Mixer module: Front panel is in near mint condition, with the paintwork and printing in superb condition. Only a couple of tiny (<1mm) blemishes. The side panels, rear panel and the base are free of marks.
104 Sequencer module: Front panel is in near mint condition, with the paintwork and printing in superb condition. Only a couple of tiny (<1mm) blemishes. The side panels, rear panel and the base are free of marks.
109 Speakers: Both speakers are in near mint condition. All panels are clean and free of marks.
All knobs, buttons, switches and sliders are present, original and function correctly.
The original boxes for the 101 and 103 modules are also included with the sale.
These are 100v models - a small wall plug style stepdown transformer is included for each unit." Link
“It functions %100 perfectly and flawlessly.
This sequencer is a very hard one to track down.
Lord knows it took me a wile. I haven’t seen one come up on ebay in over a over a year.
This unit just came back from Portland Custom Shop were it was professionally deep cleaned, calibrated and gone over with a comb.
The receipt for these services will be shipped with the unit.
It is missing a knob cap, but the knob functions perfectly. I would have replaced it for the cost of $20 for the exact type of cap, I just never needed to as it never got in the way of tuning the step note. Other than that, the only other cosmetic flaw would have to be a few tinny little paint scuff as seen in pictures.
All in all not bad for being from the 70′s. They just don’t make em like use to.
This thing is built like a tank and its heavy.” Link

“Roland System 100 Model 101
Wie der ARP 2600 ist auch das Roland System 100 mit seinen Modulen intern vorverdrahtet, so dass der Synthesizer direkt spielbar ist mit Patchkabeln aber im Signalfluss verändert werden kann.
Diesen Roland Synthesizer habe ich 1979 im Synthesizerstudio Bonn gekauft. Er wurde ausschließlich gelegentlich im Heimstudio benutzt. Er funktioniert wie am ersten Tag. Das Gerät wurde nie geöffnet, es befindet sich im Originalzustand.
Vorne auf dem Gerät befindet sich noch ein kleiner goldener Aufkleber vom Synthesizerstudio Bonn, also dem Geschäft, wo ich das Instrument gekauft habe.
Interessant ist auch die Anleitung zum Instrument, dort wird die Funktion des Synthesizeres auf sehr anschauliche Art erklärt.” Link

Pictures are accurate and reflect the wear and tear. It’s over 35 yrs old folks, so it’s got some use . There’s tape marks and scuffs here and there, but it plays.” Link
“Up for sale is my ROLAND SYSTEM 100 FULL SET!
As you can see from the photos it really is in excellent condition, hardly used from new, this is as good as you can get.
As you may already know, this classic analog set is very hard to come by. A beautiful semi-modular monophonic synth consisting of five modules, different combinations of these components can be used to create amazing sounds & sequences.
Recently check over by well-known tech Tim Wallhead – everything is 100% fully functional.
Comes with the following:
Original boxes for the 101 & 103
Monitor speakers 109
Spare patch leads” Link
“Selling a roland system 103 mixer for 100 series. I bought this from modeless factory a japanese seller and refurbisher of synthesizers and it has been fully gone over and voltage set to US power.

“The Roland Synthesizer 101 was part of the 5 module System 100, the Synth 101 being the heart and soul of the system.
This rare, mint Synth 101 is a 37 key analog mono synth with controls for the VCO, LFO, VCF, VCA and more.
The tone from this synth is suprisingly and shockingly thick, subwoofer use is highly recommended!
This synth is in excellent condition and has been thoroughly tested in the Roland certified service department of Professional Sound and Music
Made from 1975 – 1979″ Link
“The synth is in fantastic Condition and only a few minor things are keeping it from being Perfect.
I never saw a nicer one, it has no rust, no tobacco smells, no scratchy pots, no missing screws, feeds, etc.
All the old PSU Caps are replaced with new ones, no dust or dirt inside, always kept it under
the included cover.
It operates on European Voltage, if you want to use it in the UK you need a (cheap)
power plug/inlet converter, just for the plug (or replace it) not for the voltage.
Check picture 5 to see the original Euro plug. ” Link

“Offered here is an incredibly unusual double System 100 104 step sequencer. The units have been professionally fitted together to make a 4 x 12 steps sequencer. The unit is in very good condition and the modification does not impair the unit’s original functionality. Each unit has a toggle switch which as far as I understand is not wired (deactivated.) UK 230 volt power so a step up power converter will be necessary.” Link
“Up for sale my Roland System 104 sequencer including the original instruction manual. I used it in my (non-smoking) homestudio. Fantastic mid 70′s analogue step-sequencer with 2 x 12 steps. Part of the big Roland System 100 semi-modular synthesizer. The 104 is in great condition, cosmetic 7.5/10, with only minor pitting to the front surface of the unit. A truly great vintage sequencer, also in combination with other vintage synthesizers. The sequencer has been fully serviced and calibrated in March 2012. It’s a 230 Volt version with UK plug fitted. ” Link

“This is a vintage Roland System-100 Series Model 104 Sequencer. This is a rare find and a must for anyone who wants that classic Roland sound. The “System 100″ is the preferred system to use for it’s warm sound and it’s widely used by some of the greatest synth performers around.
Unit is in good condition with minor scuffs and marks from normal usage and storage. It’s missing one knob on Channel B/12 – but you can easily turn the shaft without the knob there. It uses standard screw-mount knobs so it should not be too hard to replace. All knobs turn properly, all buttons and selectors function as well.
Unit powers on when plugged in – the gate off light illuminates as well as the Channel 1 LED. I don’t have any other Roland components to test with, but it should be in fine working order (given that it is vintage analog, it may need cleaning).
Unit operates off of standard 110/120vac US electricity. Use in other countries may require the use of a step up/down transformer.” Link
“Selling a nice Roland System 103 mixer, works great! It’s a really fun to use and gorgeous mixer. It’s got a real dirty sounding spring reverb that is wonderful and the overdrive/distortion on the mic input is amazing sounding. It’s got the ability to power two small speakers or send line level out, which is super cool if you like to mic speakers or just jam out. It’s really pretty useful because of the reverb, overdrive and the ability to power speakers. Unit is in pretty darn good shape, there is wear on the unit but nothing too bad it’s like 8/10 condition.” Link
“Verkaufe mein voll funktionstüchtiges Roland System 100. Zur Auktion gehört sowohl das Keyboard (Basic Unit 101), als auch der Expander (102). Beide Geräte funktionieren gut. 3Regler krackeln ein bischen, funktionieren aber in vollem Umfang.
An diesem System100 wurde jeweils der Frequency Regler im VCO gegen einen gerasterten Range Regler getauscht. Dadurch lässt sich die Tonhöhe direkt einstellen.
International bidders are welcome.” Link
