Yes, pretty much so, but thanks, "24 bit", I appreciate it!
If there isn't anything called "FDDITalk" or similar on this particular DevCd, then October '93 could be removed from the checklist, together with November '93 that I checked myself.
As to the 1991 disks, it's better to start with Volume #8. That one should be from August / September, I guess.
