I did some more research and it seems that the board thickness may be an issue. A 4-layer board from most fab houses would be about 1.2mm thicker than the original. A 2-layer design would probably be feasible, and flatpack SMT ICs may make it easier.
EDIT:
Does anyone have potentially useful information? I think pentium said something about this... any such information may be useful. |

There is like, five pages of content and links. Go back and read them and you will find all you need. _________________

Ohh I've read all that. I mean, any additional information that isn't here.
I'm sure I can do without it, though. |

If someone is willing to donate a DSP simm, I can work with grant stokely (make of the altair and kenbak reproduction kits) to build a lot of these simms. It may cost a bit, so we would all need to split the costs.
Too bad I sold the only DSP simm I had 6 months ago =( |

This may be a dumb question but what would this device do for us? Sounds like it offers more memory to DSP functions but is the DSP that heavily used where we would see speed improvements someplace?
Just trying to understand what an upgrade like this would do for us commoners.

We have all the reference material we need to reproduse the SIMM here in the thread. That is about sa good as we are going to get when it comes to getting hold of a real SIMM.
We really don't know what it will do. Even I think it's really just a fun and novelty item. _________________

That's really the most important question. My recollection is that only the CCRMA MusicKit and some other custom stuff (perhaps IRCAM) will use the added memory. I may be wrong but that's the story I know. |
