Program Recorder

[wierd_w]

Well, I mean, if you WANT to solder up something, you totally could--  You would need 2 mono headphone female jacks and some protoboard...  But it's not worth it in my estimation.

Did you have to replace the belt on the program recorder, or had it survived the ravages of time?

[wierd_w]

I think he is using a non-TI cassette recorder.

It appears that time was on this one's side...in truth I didn't think I going to be lucky enough to find an original.

PC2TI v0.1

 

On the stripped male connector the red wire is tip, white is base.

 

White (Earphone) TI wire connected to Tip.

Red (Mic) TI wire connected to Base.

@wierd_w

I know you said it wasn't worth it ... I just kept having the wires slip off. Wanted something to make sure that the connections remained solid through the transfer.

Now I am a total noob when it comes to actually working with  programming on the TI. So,  I am gonna run though the "Getting to know you" book. The Big yellow one. see if I can't teach myself something..... annnd get rid of this damn mechannical keyboard that loves to ghost in letters.

TI to PC.  The saving to the recorder should only be done by the TI. The ground loop issue is addressed internally in the recorder, from what I can tell.
 
The TI really belts out the signal, while the PC kinda just half-asses it, even with volume turned up to 130%.  Saving from the Ti assures proper output levels.

Looking for this in the FAQ. Thanks !

TI REC Cable Tip -|

                           |-->PC Cable Tip

TI Playback  Tip --|

 

 

TI REC cable sleave -> PC Cable sleave

 

TI Playback sleave -> NC

 

 

The grounding issue is that the REC tip is not connected to ground properly, so when it is plugged straight into the PC, it has a "Floating ground" and produces an awful hum. This makes it very hard for the TI to properly decode the sent audio, especially since the PC is not really loud enough. (barely loud enough with VLC doing the playback, and volume turned to 130%. Still not as loud as the TI belts it out though.)

 

From what I can gather, there is a common ground inside the program recorder, which makes this problem magically go away once both leads are plugged.  However, that common ground does not exist plugging the REC cable straight into a PC's headphone jack-- hence the hum.  The goal here is to connect the REC cable's ground with the playback cable's ground, so that something like a common ground is obtained using the TI's electrical system exclusively.  It works.

Is it working for you?

[Mehridian Sanders]

first attempt is a "ERROR - NO DATA FOUND", even at 125% output.... gonna try some volume work.

 

[wierd_w]

I could be a bonehead, and have REC and PLAY mixed in my head... When you play the wav file, do you hear the playback on the TI?  If not-- Swap the cables in your thingymajig.

swapped em, but still no TI output. Lemme make sure that the signal is still getting through.

hahahahahahah I derped the connection... hang on reworking connection

 

[Mehridian Sanders]

so... helps if you don't  try and take everything from ground.

 

got signal to the TI

 

"DATA OK"

 

[Mehridian Sanders]

recording to tape successful. 

Checking Data..

DATA OK

[wierd_w]

Yup.  When saving to cassette, always do so from the TI.  The PC is just not loud enough.  It's barely loud enough to send to the TI in place of the recorder, but the reduction in volume when played back from tape is too great, and you will get read errors.  Load into the TI's memory, then save from the TI.  No problems then.

Thanks Wierd... I just noticed the misspelling and found it to make sense ... Wy Erd. Weird Wired.. like it.. kinda like my brain sometimes. Lol

Thank you kindly to all who were working with me on this! I was so excited to have this work.
