"The rarest drum machine in the world – the Anvil Percussion Synthesiser prototype. As featured in a major (four-page!) Electronics & Music Maker article in the magazine’s June 1985 edition. The Anvil prototype drum machine was intended to offer user-sampling and programmable rhythm sequencing as well as a drum synthesizer section that could be triggered by pads. However the project was perhaps too ambitious and the development money ran out in mid-October 1985 before it could be completed, leaving the Anvil residing in its flight-case in a London basement for 33 years before being tracked down. The Anvil prototype is not currently functional. A final update provided by engineer Roy Gwinn indicated the top board (control panel etc.) had been operational for a year (to October 1985) and was reasonably reliable. The bottom board (sample/synth) software had been able to sample into memory, replay from memory and save/load to floppy disk. The synth section was seemingly nowhere near completion, and some software had not yet been written. This was late-1985, and the Anvil has probably not worked since then. The Anvil has been powered up recently but the 40-character display was non-functioning. The 3.5 inch disk drive appears to be non-functioning. There are various builds of software/firmware on 12 EPROMs, some of which are populated on the two boards (PR for top board, BB for bottom board), along with two BIOS EPROMs. One early build EPROM (BB) has had a pin repair, and the other has a missing pin altogether. Some EPROMs have been confirmed as having data on them, and two have been copied in a limited (unsuccessful) attempt to get some life out of the Anvil’s top board. The internal battery has recently been removed from the unit. The auction includes the Anvil, the now-external/separate XLR-XLR input 240V mains power supply (with original UK plug), original Bulldog flight-case, the EPROMs, the schematics it came with (which in some cases differ from the current internal layout), a faded computer printout of the menu commands and final summary of work outstanding (16/OCT/85), and a unique (copy 1 of 1) professionally printed Preliminary User Manual written by the current owner collating all the paperwork, user guide, scans of schematics and his own personal full-colour photographs. CAUTION: PROTOTYPE – Should only be powered up by a suitably qualified electrical technician under close monitoring. The Anvil will require significant work to be restored. Weight: 22.3kg in flight-case. Dimensions 68cm wide by 43cm deep by 21cm high (in flight-case)."

"Greetings everyone and hope you are having a lovely day. Im putting up for sale this rare very last member of Roland's fully analog drums era... 42 years ago. Instrument itself is in pretty good condition (few minor bruises and scratches, nothing major) and actual drum machine works perfectly (I cannot confirm the other features like chord or bass, since they are active only in cooperation with Roland HP keyboards). Also a sidenote, since it is a very early midi instrument and mainly designed to work with mentioned keyboards, midi works as clock in/out or start, but doesn't allow to trigger individual drums or accent. Unit was originally for Japanese 100V and has been internally switched to 240V and while I was at it, I have replaced power supply filtering capacitors with new ones for good measure. Thank you all the best."

"First Drum Machine from ROLAND : model TR700 the grandfather of CR78. It's in very good conditions for 54 years old instrument. It has a mods for to use with 220V but still has the original plug from Japan. Fantastic sound like CR78 but BD like Tr808."

"Modified Roland TR-606 dubbed the TR-608 As used by Hainbach. Takes the humble TR-606 and supercharges it into 808 territory and beyond with tuning, decay and tone mods. Incredible modified Roland TR-606 for sale. This is the TR-608, believed to have been modded by Filippo Samore. As used and loved by Hainbach (video below) who had this to say about it: “The mod is high-quality and truly enhances the sound engine of the 606 without compromising its handy form factor. It is almost like a TR-808 now, except maybe a little more interesting, because it is still a charmingly shuffling 606 at its core.” https://youtu.be/aovvoLD2BCs The main modification in this revisited classic is the complete redesign of the kick drum circuit with a lot of borrowed technology from the 808. - On the kick, It adds: Tune, env Control, tone and decay. - Similar thing with the snare, same borrowed technology from the 808 but with an improved decay length. - It gives access to tune, snappy and decay. - It adds tune for L.H toms independent from each other and cuts out the annoying noise present in their circuit. And finally the modification taps into the original circuit of the hi-hats opening the way to hands-on control of : Tune and decay, separate for both open and closed hats This example has had individual outs for kick, snare and toms added. It also has a Kenton Kadi port installed for anyone who already owns a Kadi box or a Kenton Pro with Kadi capabilities added then you are definitely cooking with gas! Voltage Information: Takes a standard 9v power supply (not included).
Lots of interest in this, so a couple of answers to questions: 1) The individual outs are Bass Drum, Snare, Toms 2) Each individual output has a fixed volume and is completely independent of the master output. You can still feed the bass drum out through the master output if you want. Or turn it down to mute it from the master volume. 3) Din Sync is untouched and works as originally intended by Roland."

Grendel Drone Commander - rare V.1
Note: links to listings are affiliate links for which the site may be compensated.
via this Reverb listing
"The very rare, and very elusive Grendel Drone Commander. The only synthesizer built out of a used 7.62 NATO ammo can. Only 750 were made and they very rarely make it to the used market. With a total of 9 knobs, the Drone Commander offers two manually-tuned oscillators and two LFOs, plus an unusually colorful and nasty filter. LFO1 is an analog variable-shape oscillator, and LFO2 is a pulse waveform that auto-synchronizes to LFO1 at a ratio of 2x, 4x, 8x, or 16x. Both LFOs can be routed to the filter for rhythmic patterns. A line-level output jack is provided for connection to amplifiers or effects."
