Artoj Posted April 30 Author Share Posted April 30 Hi All, This is one of the most dense boards yet, so I hope I haven't made too many errors. This is on the list for the PCB's to be made. Regards Arto. 2 Quote Link to comment Share on other sites More sharing options...
Artoj Posted April 30 Author Share Posted April 30 Hi All, I have been checking out some great work from JasonACT(PPEB), JJB (APEDSK99), and Speccery (Picoart) besides S Conner, Rickydean and OPA Gary revitalising all the earlier work, I am amazed these guys are really pushing the little orphan to the limit. So I have made an addition to the MPEB line up, the Jumper Board, it can accommodate two TI99 44pin side port connections on top and one to the opposite side, also the two 44pin header that are on all my boards, you also have access to all the buses via Male header pins. I am still deciding what to put in the large open spaces, maybe a lot of prototype pads, a power supply, switches or a lot a flashing leds (LOL). The first pic (P1000802) is the the MPEB connection to the TI 44 pin port , the second pin (P1000803) is the top connection using the same board, (P1000804) is connected and (P1000805) is with out the FM header pin connector and finally the 3 connectors. The left connector is the FM header, the other two are the same but the one on the right has the pins slightly bent to grab the board. This board is on the PCB print list as well.

Artoj Posted May 1 Author Share Posted May 1 2 hours ago, HOME AUTOMATION said: Can I use this to make the speech Synthesizer talk! It is even funnier when you realise you can manually select the registers and toggle the data by hand, the TMS9919 is not even needed as there is an audio amplifier on board. You have to carefully workout which sequence of switches you need to get it to say a simple word, it would be painfully tedious but not improbable. You have to think like the TI-CPU and act like TI-BUS at the speed of a snail about 0.099 hz. The Speech Synth has an Oscillator on board so all you need is the correct sequence of signals to the registers and data selection in the ROM to trigger a word. I would guess it might take you about 1 hour of toggling switches, without a mistake, LOL, regards Arto.

What I'm using now is far too EASY... As for toggling switches w/o a mistake ...Far too easy ...I'll have to replace them with SHIFT REGISTERS, that I can operate with three switches ...then I'll be ready-to-go! 2 Quote Link to comment Share on other sites More sharing options...

Great idea!!! It looks like adding a small daughter board might be a good option, I'll look into that at some point, but if you want to modify the circuit to add this option, you are very welcome, keep me posted, regards Arto. 1 Quote Link to comment Share on other sites More sharing options...
Artoj Posted May 3 Author Share Posted May 3 Hi All, While mulling around an open TI motherboard I realised a simple circuit to test for Keyboard problems. I am getting ready to get a few boards made so I need to have as many as possible for my order. Here is the circuit, regards Arto. 15 x 3mm leds 1 x 9v battery and holder 1 x 25 ohm resistor 1 x 15 pin male header with 7mm (9/32") long pins like the mother board. 1 x pcb board size 3.2" x 2.2" (81.28mm x 56.007mm) 4 Quote Link to comment Share on other sites More sharing options...
Artoj Posted May 4 Author Share Posted May 4 Hi All, I am now pacing myself to get as many MPEB cards ready for PCB prototype production. I have mashed the FORTI Music Clone with the Digitiser and Clock card. I have the card about 80% wired at present and running into issues, I need to take a breather for a couple days so the conglomeration gels in my head space, LOL, here is the card at the moment. Regards Arto. 10 1 Quote Link to comment Share on other sites More sharing options...
Artoj Posted May 5 Author Share Posted May 5 Hi All, I have completed the MPEB TI99 /4A Music Card V4.0, while I am waiting for another 3D printer to arrive, I will optimise and tidy this board and all the other boards that will be made.

Artoj Posted May 10 Author Share Posted May 10 Hi All, Testing the 3D print, they still need a bit of tuning, regards Arto. 7 Quote Link to comment Share on other sites More sharing options...
Artoj Posted May 15 Author Share Posted May 15 Hi All, I am still tidying all the MPEB boards, in the mean time here is the 3D printed Box and it's first run, it failed on part of the print, which is fine as this is only to test the board fit when they get made. I caught the Digi bug so it gave me a reason to add the MPEB Jumper boards I was planning to include in the future. These Jumper boards fit on top of a MPEB board and are an addition to the base board underneath, like the one I made here where you can use the TI to create stereo audio output from your digital data.

+dhe Posted May 16 Share Posted May 16 Hey @Artoj ! Are you going to be taking orders for boards, or will you be uploading the cadd files and having folks order their own? I'm looking forward to getting boards of a couple of your designs. Thanks! 2 Quote Link to comment Share on other sites More sharing options...
