Rare Vintage Eletech VP-870 PC Voice Card 8bit ISA for IBM PC XT AT

I can find no record of this specific model.  I was only able to find info on the VP-880.
This is not a typical sound card, in the traditional sense.  It is used for recording and playback of audio.  Nothing more, as far as I know.
Include original manual, software, and one audio cable, as shown.

I can't test everything I sell, but I will stand behind it.  Return for any reason!
