While browsing @geneb's Internet Archive uploads, I came across this weird copy of PC-DOS 1.10. It is weird because it came on an 8" disk, in CP/M format. Had that been the only anomaly, I might not have bothered mentioning it. However, what adds an extra layer of peculiarity is that it differs from the PC-DOS 1.10 available online.
I extracted the files out of it and compared them against the well-known copy of 1.10, 5 files (IBMDOS.COM, DEBUG.COM, DISKCOMP.COM, DISKCOPY.COM and FORMAT.COM) are different and it contains 2 extra files (GRAPHICS.COM and VENDOR-#.DY1). I'm not exactly sure what the differences are yet. Could it be a later (and maybe unreleased) version of PC-DOS 1.10?
I'm also curious why it's on an 8" CP/M disk. The files are in the exact same order as the official PC-DOS 1.10 release and the system files even have their attributes set.
The raw files from the 8" disk are in "dos_disk_files.zip" and a reconstructed bootable 5.25" 160K disk (with files truncated down to their actual sizes) is in "dos_disk_160k.zip".
