Well, 7680 bytes = 60 128-byte sectors, which is more than the first
two tracks on an 8" floppy. I suspect that the "file on the site"
is from an implementation where the boot track was double density
or on something other than an 8" floppy. (30 256-byte sectors,
15 per track, maybe? Sounds like a 5.25" DD format.)

According to my DR "CP/M 2 Alteration Guide", track 0 sector 1
is the cold start loader (bootstrap). Track 0 Sectors 2-17 are the CCP.
Track 0 Sectors 18-26 and Track 1 Sectors 1-19 are the BDOS. And
Track 1 Sectors 20-26 are the BIOS. This is for a plain-vanilla
8" SSSD installation, of course.
