not the best shots, but some interesting bits: "K-TRONIK CUSTOM PROTOTYPE ENCHIDNA DUAL CHANNEL STEP SEQUENCER & DUAL CIRCUIT BENT SPEAK & SPELL SYSTEM WITH OPTIONAL MIDI MODULE. THIS is the ONLY SYSTEM of It's Kind.
It is A Unique Modular Synthesizer System Comprised of A Custom Encased Enchidna Sequencer with Dual Linkable Buses, Two Fully Professionally Circuit Bent Texas Instruments Speak & Spell Units & A Dual Channel Midi Module for Use in Dual Circuit Bent Instrument Midi Sequencing.
This Unit was Specially Designed & Custom Built For Me by K-Tronik ( http://ktronik.com/echidna.html ) Who Collaborated with Peter Edwards of CasperElectronics on a Number of Particular Instrument Designs; -Specifically the Highly Sought TI Units Employing the Double Stacked Knobs Employed in this System... These Double-Stacked Knobs are No Longer in Production & This Design Can Not be Reproduced... So This Is It...

ALL Four Units Are In Perfect Condition -& All Switches, Knobs, Ports & Membranes on All Sections are 100% Fully Functional. The Sequencer Unit & the Midi Brain Unit Both Employ Readily Available Ports Hardware that can be Utilized to Connect Other Instruments & Devices For Either Enabling Sequencing Or Midi Control of Other Devices or Both.
The Sequencer & Both Speak & Spell Units Run on standard 6v DC Adaptors. Both Speak & Spell Units have 1/8 inch Outputs for Insertion to Doepfer, Cwejman; or other Modular Synthesizer Systems For Filtering, Effects Processing, Amplification & Recording.
If You Are Into Sequencers, Modular Synths & Circuit Bent Devices; This Might Be the Pivitol Experimental Sequencing & MIDI Package You have been Waiting For."
