Weird OSs

Once upon a midnight dreary, Derek Peschel had spoken clearly: But... what (I think) you're referring to may not count. Like the ROM-based DOS for the Tandy CoCo was considered either DECB (Disk Extended Color Basic) or RS-DOS, depending on who you ask, and when. Plus, for the Z-80 side of RS, you had TRSDOS, LS-DOS, NewDOS, and prolly more I've never heard of, but *none* of these examples are what Zane was originally referring to, for DOS is only a subset of the entire, correct name. In fact, MS-DOS and PC-DOS wouldn't even count for his argument. (CompSpeak: RS-DOS != MS-DOS != NewDOS != DOS...) Likewise, if there was an OS called PPOS, or NewPOS, these wouldn't count either. That is, if I read his statements right. Question: How many DOS's were just "DOS?" No more, no less, just "DOS?" Just a thought, Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.
