Dark Star Chaos info

Post by bunkerspreckles » Fri Dec 12, 2014 2:44 pm

Hello

I just got a semi-functional Blacet Dark Star Chaos (powers up, but no output) that someone else DIY'ed, and I'd like to try and get it going.

I have the basic manual from the Blacet site which diagrams the panel wiring, but doesn't include the rest of the assembly, parts list etc included in the full manual which i'd like to refer to.. I haven't been able to find a pdf online, I'm wondering if anyone around here has a copy?

Thanks

Blacet is usually pretty good about providing documentation if you ask nicely. He doesn't post his schematics etc. online for intellectual property reasons, but since the module is discontinued I don't think he would have a problem sharing the info with you. Regarding the repair, the first place I would look is the SN chip.

Thanks for the tips :tu:

I've read that the SN chip is sort of notorious for popping out, i'll check it first thing when i get the dark star in the mail.
And also will see if Blacet can hook me up with documents.

Hi ARY

I have a PDF of the DSC layout on my computer at home, I don't remember if it
has part values on it or not, but will check and get back to you after work.

I have a Dark Star and I think I still have the manual in print form. Let me know if your still looking and I’ll dig this up. I could send send some pictures of the module if that would help.

I sold my Dark Star packed it up and mailed it with manual this morning! I completely forgot about this thread. I’ll contact the buyer and ask if they would be willing to post pictures.

In the meantime I dug this up over at Electro-Music.

Looks like Thomas Henry has similar project here: https://www.birthofasynth.com/Thomas_He ... _main.html

The thing about the DarkStar is it’s based on the SN76477N Complex Sound Generator Chip. The module is really just an interface for this chip.ibthought these would be impossible to find but it looks like you can still get these: http://www.arcadeshop.com/i/994/complex ... r-chip.htm

Oh wonderful! thanks so much for digging far better than I, Ive been reading Thomas Henry's awesome site on breaks at work, it did seem that they are conceived very similarly. Really appreciate the schematic, that looks like what Im seeing here. I have a busted decay pot that I have to track down so this is very helpful, thanks again! :sb:
