+DZ-Jay Posted May 24, 2013 Share Posted May 24, 2013 By the way, make sure to include access to the expansion bus, just like the original. That removable tab on top was intended to allow for expansion modules. I know that none were ever made, but I've seen old threads where using it for new hardware has been discussed. You don't want to cripple your design by missing out on compatibility. -dZ. Quote Link to comment Share on other sites More sharing options...

JohnPCAE Posted May 25, 2013 Author Share Posted May 25, 2013 (edited) It wasn't at all easy. Unfortunately, while I can "test fit" in the editor, there's no way to tell how easy or hard it is to remove the panel without actually making it. The next step is to model the knob. I put in a lip around the hub (visible here) to try to keep dust or dirt from getting past it. Edited May 25, 2013 by JohnPCAE 2 Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted May 25, 2013 Share Posted May 25, 2013 With the expansion "hatch" the way you have it now I think it'd be very hard to get it open without breaking one of the retaining tabs. How about a hatch door that slides in and out instead? Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted May 25, 2013 Author Share Posted May 25, 2013 (edited) It would be hard to model. Here's a refined model that has a better cutout area, a knob, and a cover with better tabs. I also did a test fit to check fitment. Edited May 25, 2013 by JohnPCAE Quote Link to comment Share on other sites More sharing options...
Uzumaki Posted May 25, 2013 Share Posted May 25, 2013 Personally I wouldn't worry about the hatch breaking off if someone tries to take it off. There hasn't been any upgrade for 30 years and I bet many never knew that the framed logo is actually a cover for expansion. I didn't know either until I took apart one to clean it some years ago. If there is a plug in expansion, odd are it'd be too big to hide under the cover and would stick out. I mean you can't burn a G1 ROM at all and fabbing your own G1 compliant ROM is expensive as heck for just one small run. EPROM with either logic chip or CPLD to deal with address muxing would still be a lot cheaper and still be bigger than the little space under the cover.

Games For Your Intellivision Posted May 25, 2013 Share Posted May 25, 2013 I think it is cool that you are doing a design based on the Intellivision II Intellivoice.....but, if you redesign it, how are you going to get the 'voice volume wheel' up there on the top? Don't you have to essentially make a new case for the existing boards, which have the wheel out front? Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted May 25, 2013 Author Share Posted May 25, 2013 It will definitely require a new board...but that's not my job Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted May 25, 2013 Share Posted May 25, 2013 It will definitely require a new board...but that's not my job In my opinion the need for a new PCB negates the need for the expansion hatch. Losing the hatch would also simplify the plastics design and therefore the moulding requirements - win-win all round . Quote Link to comment Share on other sites More sharing options...

JohnPCAE Posted May 26, 2013 Author Share Posted May 26, 2013 (edited) The original board will never fit in the case as it sticks too far out the front, unfortunately. The Inty II form-factor is just too different. Edited May 26, 2013 by JohnPCAE Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted June 9, 2013 Author Share Posted June 9, 2013 Here is a link to my finished models for the four Intellivoice II pieces (bottom, top, knob, door). It includes four .stl files and two FreeCAD files. One FreeCAD file contains only the bottom case model and the other file contains everything else. http://www.mediafire.com/download/ajz264j1l2lja44/Intellivoice_II.zip 3 Quote Link to comment Share on other sites More sharing options...
+fdr4prez Posted November 14, 2015 Share Posted November 14, 2015 I understand that the original board is too far forward, but what would a morphed case look like that mimics the Inty 2 style, but allows for the use of the original board? Is 3D more doable these days compared to 2 years ago when this thread was started? There was another member that recently offered some 3D printing for new controller designs. If you google "3d printing services" there appear to be many companies offering this service, and a handful near me in the Silicon Valley. Not sure of pricing, or size limitations, or color availability. Maybe 3D printing may be more viable these days compared to designing and making a new board.

JohnPCAE Posted November 15, 2015 Author Share Posted November 15, 2015 There's another thread called NanoVoice where I took a stab at making a full Intellivoice board within the limitations of the free version of Eagle. The circuit design is complete, though totally untested. That board can fit in almost anything. Quote Link to comment Share on other sites More sharing options...
+fdr4prez Posted November 15, 2015 Share Posted November 15, 2015 Hmm, it's all through-hole except for the edge connector for the cart? If someone can get a couple PCBs made, I have access to a selective soldering machine for soldering up a few prototypes Quote Link to comment Share on other sites More sharing options...
JohnPCAE Posted November 15, 2015 Author Share Posted November 15, 2015 (edited) I uploaded it to OSH Park, if anyone is interested. https://oshpark.com/profiles/Hustin13 Their rendering doesn't accurately represent what the board will actually look like when you get it -- the Eagle files are what it really looks like. For some reason, their rendering makes pads too large such that clearances look a lot smaller than they actually are. Thread link: http://atariage.com/forums/topic/217742-nanovoice/?do=findComment&comment=3368509 Use at your own risk! It's **untested**. If you test it, use an Inty, board components, and a cart that you don't mind seeing fried! Edited November 15, 2015 by JohnPCAE 1 Quote Link to comment Share on other sites More sharing options...
+evg2000 Posted May 27, 2019 Share Posted May 27, 2019 Anyone know of any 3d printer filament that is the same, or close to the same color as the INTVII? Asking for a friend Quote Link to comment Share on other sites More sharing options...
