Roger Waters' VCS3 & Synthi sequencer schematics? Re: [sdiy] pink floyd and EMS

Hi
The EMS KS sequencer schematics are here:

http://www.hinton-instruments.co.uk/ems/ks.gif

As used in the Synthi AKS and DSOTM. However the shift registers are
obsolete and nearly impossible to find. But good news, it's really easy
to replicate this 30 year old design in a modern digitally based synth
module.

Ditch the blue touch keyboard and assume people have MIDI keyboards to
drive their analog CV based gear. Implement x2 CV and gate (note,
velocity, note on/off) with 256 non-volatile memories, stable 12-bit
DAC's, "bubble" 7-segment red LED displays for sequence length and
memory number. Memory location selected by a rotary encoder. Keep the
V/oct tune feature as a front panel control and the transposition pads.
Add in the single shot mode of the EMS Universal Sequencer and keep Loop
+ Random modes. So in 2007 we will launch an Analog Metropolis module
that does the job of the (A)KS Sequencer.. and it will be cheap. Unless
Doepfer get there first.

I really would like to clone the Synthi sequencer.
