[sdiy] cloning the paia 2700/2720 - is this it?

[Mike Brown]

dood-
I've got this book titled 'electronic music circuit guidebook' by brice ward
with tons of paia circuits...

- nine transistor wind source
- steam whistle simulator
- surf synthesizer
- "infinity-plus" sustain
- synthespin
- gnome controller
- gnome noise source
- gnome vco
- gnome gnome vcf & env shaper
- gnome vca
- all those 2720 circuits you listed
- 2720 sine converter/pulse width modulator
- 2720 inverter/buffer
- 2720 keyboard

it also has schematics for an electronic piano, stylus operated organ and an
extensive circuit for some crazy-ass drum machine using sn76489 chips + a
load of other cheap transistor circuits...

and hey!  in some cases, you should use 748s or 709s or 301s where they're
specified....  I've got a load of 748s, so shoot me an email offlist if ya
want some.  actually shoot me an email anyway...
