Does anyone have a Digi Port?


Omega-TI

Recommended Posts

I'd like to learn more about this device, possibly even see a schematic or get my hands on one.

The idea of being able to play a .wav file on the TI is interesting.

 

I'm not sure how often I'd use a device like this, but the price looks right. I'm wondering if it was ahead of it's time or just too late to catch on? Ether way, this thing looks like it could have some potential so I'd like to learn more.

 

... thinking out loud...

 

There are a lot of really CHEAP amplifiers << HERE >> a person could use...

Chris' USB power port project would work in the P-Box too, or one of a 1/2 dozen converters I already have...

 

I know I have a pair of old PC amplified speakers laying around too...

I suppose I could 'update' the finish to match the TI's black & silver styling like I did with the trackball....

Use decal sheets to put a TI logo on them when I'm done...

Hmmm....

I may have found my next project....

 

How do I get a hold of this guy to order one?

Here's an album of what I have what I paid and the manual pages..

It plays RAW/PCM VOC files not WAV files, WAV's are compressed and the TI has no ram or free cycles to do that work and play a sound.. WAV's are easy converted to PCM though.

Most WAV files are NOT compressed, but these days format conversion is trivial enough on the PC anyway. ;)

 

In the picture it looks like they painted over the IC to hide what it was, but there were a lot of parallel port audio solutions for various things, so it's a safe bet that it just converts the parallel output from digital to analog. (A lot of solutions just used a resistor array - here's a simple one that will work on any 8-bit port: https://www.ikalogic.com/8-bit-digital-to-analog-converter-dac/
