Hi, can anyone tell me the difference between these 2 Noise Ring models? GR-1210A and GR-1210B

The newer version includes the noise output and ext chance while the original does not.

I always wondered why the dip switch for invert data recirculated
through shift register wasn't put to front.
And why there isn't standard an external clock input.
These function should be avaible from the frontpanel.
Cheers,
Dennis

On that page I see one called GR-1210 (no A or B suffix) which is missing the jacks you mention. I have the GR-1210A which is also pictured in the link you sent. But I just saw the GR-1210B and there is no difference in terms of jacks and controls. The B is a blue faceplate and different knobs - maybe that's the only difference.

oh haha. yeah. i was at work when i replied so i didn't have mine as a reference but that's exactly right. i have the blue one and it is indeed the same functionality. just a beautiful blue faceplate with the awesome wiard graphics!

and just in case you guys missed message 1055 a few years ago ill post both doc and grants info.....
message 1055
A couple of folks on this list have asked me if there is a relationship bet=
ween the `Goldberg Function Generator' and the noiz ring. Until now, I took=
the fifth and stated for the record that the Goldberg F.G. and the noiz rin=
g were `just good friends' but with Grant's permission, I can now tell the f=
irst part of the story.
I created the Goldberg* in 2000. It lumbered and lurched into existen=
ce from a bunch of experiments with old CMOS that I salvaged from a scrapped=
mainframe. I was ignorant of previous analog applications of shift registe=
rs (such as Electronotes PRTWEE(sp?) and Joe Paradiso's DIY modules). The on=
ly notions I had were catalog descriptions of the Serge Analog Shift Registe=
r and my trusty old CMOS cookbook. My ignorance proved a boon to me when I t=
ried random data input WITH randomized clock pulses. Now, as Grant has poin=
ted out to me, my idea of music is bacon frying ( a fair cop, even though I'=
m a vegetarian). So I assumed that no one would be interested in this phenom=
enon except me.
The summer of 2001 was a magic summer for Wiard. Grant had a creative d=
esign spurt from which modules such as the Wogglebug have been realized. We =
were corresponding pretty frequently and he generously offered to put me up =
for a few days visit in M'waukee .I took him up on it in late July. I decide=
d that a scaled-down version of the Goldberg (dubbed Goldberg jr. – a toy -=
really) would be an appropriate bread and butter gift for my host. The deci=
sion to build a Goldberg , as opposed to any of my other contraptions, was s=
trictly one of convenience for me. The core circuit has a low parts count an=
d I only had a couple of weeks to get it ready.
Grant and I had big fun in Milwaukee but to my horror and embarrassmen=
t, the Golberg jr, failed when we plugged it in (during a torrential thunder=
storm BTW). I was forced to borrow some Wiard workbench space to try to revi=
ve it. Part of the problem was that the original circuit was designed for 12=
V operation and Grant has standardized on 15V. I added voltage regulation a=
t the last minute but didn't test all the operation conditions properly. Nat=
urally, Grant was gracious anyway but the failure compelled him to have to=
fiddle with the innards of the gadget himself after I went home.
Soon after , I was flattered to hear from Grant about the fun he was having=
with it….
And at this point I must leave the telling to him......

To pick up where Doc left off...
Actually we have to go back a little. The Buchla Model 266
"Source of Uncertainty" has a quantized voltage output formed by
a shift register and a couple of resistor analog to digital
converters.
Somehow I ended up clocking it with an audio signal, and that
sounded pretty good (like the video game sound chips). So the
shift register from the 266 with the resistor DAC was added to
the classic VCO and forms the RAND output. It's the same as the
2^n output with n always at six. The 300 series already contains
a Source of Uncertainty built into every Classic VCO (Your
Welcome!).
The SOU shift register is fed back with an exclusive OR gate in a
thing called a "pseudo random shift register". Now Doc came up
with the very clever idea of loading the shift register from a
random data source formed by a comparator sampling a white
noise generator. This makes the data "truely" random compared
to "pseudo" random.
Bernie Hutchins published a design in Electronotes called the
"Pseudo Random Tone Wheel" or PURTWEE (EN#106 Pg. 3).
That design started with a pseudo random shift register and
used that data to load a "tone wheel" which was another shift
register, clocked at an audio rate, which could be recycled or
loaded with a new bit under probability control.
Bernies original design did NOT contain it's own VCO and used
6 chips for the noise source, 9 chips for the tone wheel, 24 chips
for the probability control and 3 summers for a total of 42 ICs for
the original PURTWEE design.
I realized that by using Doc's idea of generating random data
using a comparator and white noise source, we could drop the
PURTWEE component count down to 6 ICs and actually do a
better job. Since the redesign was SO major, and we are using
an actual white noise source, I felt it was appropriate to change
the name from "Tone Wheel" to "Noise Ring" (get it?).
The last step was to add a VCO to the design for customer
convenience, and a new ultra wide range VCO was developed
for the purpose.
To summarize, the module is a Tone Wheel in wolfs clothing. A
hybrid of the MIC Rube Goldberg Function Generator,
Electronotes Pseudo Random Tone Wheel animator and the
Buchla Source of Uncertainty. "Noise Ring" seemed good since
RGFGPURTWEESOU does not pronounce well.
Shortly I will be doing a write up on the 2 hardware
configurations and other possible modifications you can do at
home.
