    checking out this guys other sells he looks like one of those that goes around to vintage thrift & antique shops, buys crap he has no idea what it is, prices high (cuz it's antique) and thinks he's going to make a fortune off each piece. In other words, a moron. 

    I agree that the prices are ridiculous.  But, his profile shows 4.3K items sold and 2K feedback with 100%.  So I'm not sure moron applies. Maybe to his customers.

  2. On the issue of interference, also consider moving the cell phone away from the area.  Recently, I was gaming online and using Discord with a microphone.  I was coming through very garbled.  Eventually found that my phone was the problem.  I can't have it anywhere within a few feet of the microphone.  I imagine the same could happen between a microphone and a TI connection.

    Is that a CF7 or a NanoPEB?  I thought only the NanoPEB connected to the side directly.

     

    In any case, I am not certain if the card can be used after formatting (if using direct access, formatting should not matter, but...)  If it does need to be cleared, diskpart can do that.

    Linux user.  I did a

    dd if=/dev/zero of=/dev/sdc

    which wrote all zeros to the disk before using the DOS dsk2cf.exe to write a volume. 

    I think it was a CF7+.   Maybe a precursor to the NanoPEB?

  4. The one I have connects directly to the side port (no ribbon cable).  The red power LED comes on showing it has power.  However, it has, what I thought was an optional, power input for use with speech module.  I don't recall having a 5 volt power supply to use with it, but it's worth a shot I guess.   When I wrote the original post, I had just PC formatted the CF disk.  Since then, I have downloaded the DOS utilities and the sample VOL1.DSK file that goes with it.  Still didn't work.  Also tried some disk images found here and no joy.    

     

    Addendum: The CF card is the original 32MB card that came with the device.  So compatibility shouldn't be an issue.

  5. So reading through a search I've found some disk images.  It appears the CF card did not have any hidden code on it.  I've also read that my side mount version was known for static zaps.  So I'm going with it being bad.   Would anyone want it (repairable?)?  I'd probably end up putting it on a shelf somewhere, because I don't want to toss it in the landfill, where it will be tossed into the landfill by my heirs.

  6. I dusted off my old side port CF7.  I must have reused the CF card for something.  Connecting without a CF7 and doing SIZE in Extended Basic shows that 32K memory is not available.  Putting a formatted CF card in the CF7 causes the TI-99/4A to freeze on start up (long tone, no welcome screen).  So either my CF7 is bad, or there was some startup code on the original CF card.  Anyone know if the latter is true?  If you have one, can you report on what happens without the CF card?  Do you get an operational 32K without CF card?

     

    Thanks.
