This might be the first Donca Matic Universal to be featured on the site.
Two pics of the inside below.
"At Herscheid & the Headbangers: Super rare Keio Donca Matic Universal Drum Machine in fair condition.
Fair condition because some functionalities are not reliable like the start/stop button. (Unit is always on basically). When using it I would just flip the sound/silence switch.
Sign button responsible for the metronome and cue will engage about 80% of the time. I doubt that many musician today will be using that feature but still prefer to mention it.
There's also a clock / clicking sound when volume is past 60% - 70% so it would benefit further amplifying before next stage or unit
EQ in perfect working order
The magic solo feature is fully working
All potentiometers are turning smoothly without scratchy noises
Both high and low impedance outputs are functional. I couldn't test the (very) old speaker connector
Tempo knob and Tempo Matic / Common functionalities perfectly working
Every program / style is working, same for every instrument + their respective on/off switch
FOX SWING section super fun to use! In good working order. The normal/quick button is working but seems to be reversed. Swing / normal working and properly set.
ADLIB MANUAL: Nice feature but will not necessary replicate the notes shown (It's basically depending on if other settings are engage or no. I don't think it was designed like this, just the old age of some components most likely responsible for this behavior)"

Roland TR-808 Rhythm Composer SN 041626 Pro Serviced w/ Kenton Midi
Note: Auction links are affiliate links for which the site may be compensated.
via this Reverb listing
"This is a really nice one considering its age. No dents, scratches, or other damages. Recently serviced by the best analog service in the Netherlands. It has the pitch mod (using the fine potentiometer) and the Kenton MIDI kit installed on the sync port. The sync port can still be used for DIN sync, but can now also receive MIDI. Supports both MIDI sync and MIDI notes, now with velocity sensitivity as well! Compatible with other Roland drum machines—just plug in a MIDI cable and start playing. All original functions still operate as intended, and the modifications can be fully reversed if desired. No holes have been drilled. The power supply has been converted to 220 volts. All potentiometers and switches are new."
