On Wed, 16 Apr 1997 22:23:30 -0400, this arrived on the list from
the esteemed Mr. Allen Underdown:
In the olden days of magnetic floppy media, there was
a sector hole
FOR EVERY SECTOR located around the hub of the floppy.
All very well and good, but there's that one extra you forgot
about. ;-)
Yes, hard-sectored disks _do_ have a hole to denote the beginning
of each sector, but to indicate the beginning of a _track_ they use
two adjacent holes. In soft-sectored disks, the single hole serves
to signal the beginning-of-track; the individual sectors are defined
via headers recorded during the format operation.
God I love reading this list!
With all due respects to Mr. Mel Brooks: "Ditto!"

Well, when your operating system is a whopping 4Kb, and
the Basic Interpiter was 12K, you didn't need much.
It wasn't that you wrote in assembler because it was
faster, but it was the only...
I stand humble to those who corrected me..

WOW 1's and O's - you where lucky! I had to use l's and O's.
Of course I cheated and wrote out all my code long hand - that was when
I was back in Egypt. I am sure you've seen some of my code 8-)

What - you had an assembler? I have to toggle in ones and
zeroes. Before that we didn't even have zeroes and I had
to use the letter 'O'. Tim. (selling his last of seven IMSAI's to a

I have that Dilbert clipped and tucked away somehwere. That one is an
all-time favorite.

Ah, IMSAIs. And seven of them! I hope to someday find one of these. It
is one of the classic microcomputer/mini's.

So what happened to the first six? Wouldn't mind one myself. Back when
they were available, an enlisted man's pay wouldn't qualify me for the
loan to get one from the local Byte Shop.
