HP Series 80 (HP-86 / HP-87) VisiCalc PLUS on Floppy Disks & Tape with Manual

Description

For sale is the software module
VisiCalc PLUS (Rev. B) for the HP Series 80 Desktop Computer (HP-86/87)
in its original storage box with the software on two 5-1/4" floppy disks, one 3-1/2" diskette, and a 3M DC-2000 tape cartridge, along with the original Manual.
I have no way anymore to determine the integrity of the software files on any of the media included.  Despite the fact that the item has been stored in favorable conditions since I've owned it (nearly 20 years), for the purposes of this sale, I would assume none of the media are still working. The software is available online.  If you have the ability to access it, you may end up being pleasantly surprised, but don't count on it.  The plastic storage box is in Excellent condition with only some smudging on the front clear plastic that I will believe can be easily removed and some discoloration at the edges of the cardboard cover art.  I suspect the real gem here is the Manual, which looks like it was never touched and is in Mint condition.  It is dated USA 6/82.
From online sources, it appears that the software (or perhaps an earlier version of it, also available online) will also run on the HP-83/HP-85 desktop models.  The manual included here references only the HP-86/HP-87, and I believe the software version (Rev. B) on the included media (if accessible) will only run on those later models.
