Here is how the VGA cable is held down. M2x20mm screws secure it to the main part. I am working on another design which just uses a VGA port that you solder the wires to.

I am not a fan of hot glue. Darryl

RF shield has to go.

Originally posted on FB... After putting it off for a few years, I finally made a nice looking VGA port for the TI99. Here is my design. I haven't yet tested it on a black console yet, but I am sending it out to a few people to try. It requires you to remove the original AV port and solder your audio wires to the board. And it also requires you to cut a rectangular hole on your console shell 60x16mm. More details to come. Darryl

For those playing on DS99, map START and SELECT to 1 and 5. Makes it a whole lot nicer to play. Darryl

If I am not too late, I would like to beta test for you. I have a small amount of homebrews that I would like to test out. Darryl

This is amazing! Thanks for sharing! Darryl

Found this at a vintage computer show. Any idea what it is and if there is some documentation for it? Not mine, but the owner would like to know. Darryl

Awesome. Can't wait to give this a try! Darryl

Yes... as well as the New 3DS and non-XL variants.

Works with cartridge installed... if it is anything like the original from the 80's. And it looks the same to me. The only reason mine is lifting up on that edge is that I have a crack in mine. Also, mine is severely yellowed.

Excited to test this version and for what the future holds for this emulator. Already, I am just having fun playing some of my favorite games on my portable 3DS game system. So glad you took on this project. So thank you! Darryl

Here is my install. Eventually I will design and 3D-print a nice piece. But for now this is it. Note: audio too.

Couple more cosmetic differences: Beige has a different power switch. I much prefer this one. It's on top and very easy to slide. Beige is missing the power LED. But it can be added if you solder it and drill a hole for it. Beige may also have beige-colored joystick and/or cassette ports. Beige is missing the sliding door that covers the side port (where the Speech Synth plugs in). Some beige units have beige keyboard overlay strips. Also, I am not sure but I think some beige units have a more efficient internal power supply board, recognizable by only two pins in the connector at the back. The part I am not sure about is if that is restricted to only QI consoles or not. Darryl

I have the same exact issue. I can see the TIPI in Windows File Explorer "\\TIPI\tipi", but on the TI, a CALL TIPI gives "BAD NAME". EDIT- I got it working. I removed the 32K, separated the TIPI from it, pressed the EPROM chip into the socket,and reconnected everything. Not sure if it was the re-seating the edge conector of the 32K, the TIPI, or the EPROM chip, but it's working now. 🙂 Darryl

I am thinking, instead of speech, additional sound capability would maybe be possible. Different wavforms (triangle, sawtooth, etc) or maybe more channels?

Thanks for this.

Yes, I consider my beige style Speech Synthesizer model finished. I will put the STL files up one day. Darryl

Mines does not work on the non-QI. Didn't try the QI.

Here are two label variants I made. Which looks better, black or green? And I added text to the edge. Darryl

OK, so I put the cpld and avr firmwares on the device. Then (on my non-QI TI), it booted it up and got a colorful menu. I also got a Review Module Library option one time. Then I got only TI Basic. On my QI, I managed to get into FinalGROM99 one time and after the first menu, (shown in the previous post with a yellow block in it), it gave me a blank screen on the next menu. I put the v1.3 firmware back on it and it's good again... at least on my non-QI. My QI shows the blank screen with a couple glitchy lines on the right side.

Not having any luck with this on my QI it my non-QI. Fwiw, my QI has 1981 rom.

OK. Thanks for the replies. I'll test on my QI console tomorrow. Darryl

If I had to guess, I'd say the chip shortage is causing the delay.
