AY-89xx series huh? I have 2 or three of those as well!

Glad I scored my boards now. I'm not suprised they are selling so quick.

i just ordered the chips as well. are there gobs of these chips sitting around out there, or is this something where the chip supply could potentially dry up?

Hi,

I have about 50 of each of the wide body and narrow body SN76477's left at www.arcadechips.com Here is a link to all the sound chips I have listed
http://www.arcadechips.com/forums.html?cPath=27_22
Shipping is cheap worldwide or in the US.
Does anyone have a datasheet on the 76488, I have the 76477 but no 76488

Thanks to all who have been buying these lately and all orders are on the way,
Mark Capps

20 boards left! It's been a busy week! I kept two for myself and want to get rid of the remaining 20. Thanks to everyone who purchased PCB's and connectors thus far.

Whatever is left, I will try to sell on Ebay since "SVdistributing", an Ebay store, is selling SN76477's and other groovy sound chips from TI, GI, NS, etc .. I will also link Arcade chips website as well since they have done us good!.

Thanks again,
Bill

Looks nice !! Good job. I took the liberty to post your panel, I hope you don't mind.

I have one suggestion, you might want to make the numerics around all the pots just a bit larger. They (1 to 10) sort of get lost. making them larger will improve this. Also, make sure the radius is large to accommodate the knob. Very Happy

Just a bit of constructive critique.

Hi

I just use ms paint hahaha and the schaeffer software.
I am not happy about the knob scales yet they are to thin.
When i get at work this night i'll ask a collega to make some nicer ones in viso.
He is pretty good in viso and i will convert them to hpgl then.
Sorry i am not sure about the panel size yet but it is the exact size of a double size Cyndustries blank panel.

Hopefully i get a reply on my email about purchasing some boards Smile

Now i am gonna design some panels for the standard wogglebug.

I could knock up a front panel in Solidworks and save it as a DWG/DXF/STL file if you want?

hey mono-poly. this panel really looks nice. its good to have that much space on a frontpanel (i build in eurorack format Sad

).

you have a pot for PWM. i can't find it on the schem. maybe you did the same mistake as me and took the 3pos turning switch for a pwm pot or do you plan to do such a mod?
or maybe i just missed something...

Um....who's Thomas Hendry? You might want to give Thomas Henry credit on the panel. He doesn't seem like the jealous type, but you never know!

mono-poly · Posted: Fri Dec 15, 2006 12:21 pm Post subject:

The only problem i have now that the BMP i got for the pot scaling almost match the ones used with Modcan/Cyndustries.
If someone could help me out with a better design that would be so great!

Yeah Fonik i did use your design a bit for the panel to look if i had all contacts/pots/switches so that's how i made the same mistake Shocked

Oow yeah what a stupid typo about Thomas his last name.
Gonna have this all fixed tomorow.
