The 3 diskette images are from CP/M-86 for the IBM PC [Not PC/XT as is more
commonly found].  They're 5 1/4" SSDD 8 sector diskettes.

What is unique about this version, compared to the PC & XT version:

This is for the IBM-PC, there isn't any hard disk support AFAICT.

The Bios INIT: entry is a few pages lower in memory.

The Boot Sector is different code, it is a one stage loader, it expects CPM.SYS
to be first in the disk directory, and first file on the disk, and of a certain
size.

There is an 'Easter Egg' banner in the boot code.  It is accessed by pressing 
all of: Left-Shift, Right-shift, Ctrl, and Alt, at the same time, as the
system boots.  It is a message from Dean Ballard, that he wrote the Bios.

[The PC&XT version has an easter egg as well, accessed by pressing the R-shift
and the question mark keys, as the system boots.  It too, is a message from
Dean Ballard, that he wrote 'much of the code'.  The PC&XT boot loader is
a two stage loader, the 1st sector loads the secondary loader found on Trk0
Sectors 5,6,7,8 into memory, this 2nd then finds & loads CPM.SYS or CCPM.SYS]

This does not have the AT-Patch installed, meaning CP/M overwrites many of the
Page Zero interrupt vectors to an interrupt trap within itself, by design.  
This is of no problem on a PC/XT, it is a problem on more recent processors.

I can boot this on an XT clone, if I remove the SCSI HD Controller from the
buss.  With a Seagate ST-01 installed, it loops reboot attempts.  With a 
Future Domain SCSI Controller, it locks up in the Banner Page.  Without
either, it works fine.
