Big project. You might contact the people who are selling
KLM367 replacement pcb's to see if they will let you use their
artwork, or maybe just buy that board from them. It's very
reasonably priced.
I have PIC code that replicates the function of the key assigner
MCU and adds Note On/Note Off MIDI. I can let you use that
if you want, for your own projects, but not to sell.
The Electric Druid web site has an implementation of an SSM envelope
generator chip using a PIC chip. Maybe it's the same SSM used in the Polysix?
But you would still need the SSM filter chips, right?

Subject: [PolySix] Polysix Full Clone

Hello All,
I have just joined the
group. Its great to see there's a worldwide community
for the Polysix.
On the other hand the big
attraction of that vintage machine, has
let the price explode within just a few years.
Hard to get a hand on one below 1000
Euros these days.
I own already a couple of
POLY 61 which can still be got around 200 Euros,
which is a very reasonable
pricing.
So while I cannot afford
the tag for a full Polysix, I've got
plenty of 2nd hand components to make synth of my own, and i
thought
Why not build a Polysix
clone from scratch?
Some may think I am crazy?
But why not?
When you have a database of
all PCBs with schematic and
layout,it's a piece of cake to
replace one CPU by another, add mods, hacks, MIDI etc,
without ending in a mess of cables and
PCB stacks..
I am skilled in using PCB
schema and layout design.So I got
schemas and layouts of KLM 369, 370, 371 already
together.
Now I want to get going
with the bigger PCBs. However what I
need are good quality photos of existing PCBs from above and
from below.In addition I've need a
scan of a SM where the PCB traces are resolved better than
on the copy that I have.
So if the one or other of
you had such photo or scans, I would be more than
happy.
If someone was interested I
will for sure share my layouts and schemas with
you.Native format is TARGET3001,
which you can get for free as pin-limited
version.
Cheers,
Tarek
