Damn, this is coming along Great. Been trying to hold off, but after watching your last vid a couple times, started hunting ebay!

First thing would be to try to find out who actually built it. Considering that it was sold at Sears, may have been Atari, but just a guess. At that time Atari's arcade div were building speech boards.
  Also look over the circuit board to try to identify the chips. It seem likely that it is based on one of the TI TSP chips. This wiki may be of help identifying chips
http://en.wikipedia.org/wiki/Texas_Inst … eech_Chips
Another chip it may be based on is GI's SPO256
http://en.wikipedia.org/wiki/General_Instrument_SP0256
  The other thing to look for is the main processor. The cartridges were more then likely roms. So if you can identify the cpu,  in theory you could make your own programs.
  So, $1 at a yard sale? Ill give you $10 smile

This would be rad to add MIDI to so you could jam away on your favorite keyboard.

My thoughts also smile

If you're willing to hack up a link cable, you can connect ground to ground, and the link cable's signal out to the sync input. Then engage the Nanoloop sync mode in LSDj. With standard setting this should give you 12 pulses per quarter note, or 3 pulses per step. Depending on what the device can accept in terms of synch signals, this may be sufficient.

I was checking out the Lunchbeat page and vids. Looks like you can adjust the Sync divide from 1 to 15. So you should be able to match the ppqn rate from LSDJ.

yogi, i've seen that and all other results for '8 bit guitar' and all other variations of those search terms like, a hundred times??
( i said i spent the last few weeks searching XD )

Good that you've seen it cause that is all you can do with a NES: midi into a cart that converts messages to register data. Go For It, midiNES rocks!

CAN'T believe that this thread has gone on so long if you knew that from the start ???

Yea but the atarivox is def based on the speakjet:

Here is an arduino project based on it:

Cool project link, serious knob action! Too bad the guy's homepage is down, would like to hear it in action.
Here is another Soundgin project

Im pretty sure that the same chip!

You can also buy a commercial synth with it

Think the GinSing's Babblebot chip is the Soundgin, but pretty close to a SpeakerJet.

I was lurking AtariAge and came across some AtariVox games in the store and some threads about it.
It's basically an Atari version of the Intellivoice for the Intellivision and The Voice for the Odyssey 2, according to this post:
http://atariage.com/forums/blog/148/ent … nthesizer/
I can't be the only one who can see the musical potential in this, right? Has anyone used this (or The Voice or Intellivoice) in a song?

A thought I had for a cart would be a very basic vocoder, you select the phonemes and play it back, like an Atari Speak-and-Spell, but I'm not knowledgeable enough with Atari programming to even know if it is physically possible to make, let alone actually code it. If there was one, though, I'd buy it in a heartbeat.

Yea I had the same thoughts, but never got hold of one. It would be cool  also on a 800XL imo smile
Here is a simular project for midi control:

As well as this Arduino shield:

Another thing to keep in mind when emulating a NES controller by recycling the controller cable, is that you will need two extra resistors to make it work on a PAL NES:

OK I have seen these Rs and included them in my design, but didn't know it was a PAL issue. good to know!

I went through the same thought process when designing the FamiiDI shield, and that's why I decided on a standard DB15 connector (DA15 if you want to get technical) - one of my NES's has the DB15 mounted and wired directly to the Expansion Port pins on the motherboard, like this:

http://www.retrorealities.com/retroreal … hp?tid=190

The other big advantage of this is that because the connector follows the Famicom Expansion port standard I can hook up all the funky old Famicom Expansion peripherals!

Thats a good idea,  much like the ENIO interface board. Good option.

I was thinking something similar actually. I already have an op-amp based circuit I built for better audio output so I already have a panel on the back. If the sync solution was small enough, could just bust out a MIDI connector on the back and call it done.

That sucks about needing to crimp though...bleh...crimp terminals and some glue solves that problem though I guess.

Newer cables may be different, don't know. But size wise we'er talking about a dip 8, a dip 16 and a dip 18, xtal and a few caps and resistors; on a proto about 1.5 x  2.5" May be a little bigger on a PCB.
I built the V1 on a Dontronic's SimmStick 18pin PIC board I had on hand, it's 2x3.5" but wastes some space. And I did a Midi thru with a 74HC00,  could just have the PIC echo any in coming byte for Midi Thru and loose the 'HC00.
Should fit in a NES, there is so much space in that case!
