RE: [analogue-sequencer] Schematics? PCB layouts?

It used to be a DIY project, kits of PCBs are pre-programmed CPUs were
available for about 2 years.
The kit PCBs were the same as used in hand-assembled production units.
After the introduction of an EU ban on leaded solder, production of
ready-built units stopped largely because hand-assembly with unleaded solder
is like having teeth pulled.
I considered doing another run of kits recently, but was unable to source
the CPUs in lead-free form except in the surface mount version.
So selling a kit including the CPU would be illegal in Europe.

It's unlikely that kits will be available again, unless the code is ported
to another processor that can be sourced in lead-free form.

Alternative production units are still under development, but with the
introduction of yet more EU legislation to make small-scale electronic
manufacture even less viable, who knows whether that will happen...
