Funny you mention this because in 1990 I was working in a school and the
deputy head teacher considered I was light years in front of their IT guy
(10 computers and a steel door?).
The guy was doing a Masters degree and had all his thesis on a floppy
disk...... You guessed. It became unreadable and he was sweating buckets as
the deadline was approaching....................
PLEASE came the plaintiff cry can you help me. Hmm I thought what's in it
for me? Then I remembered he had said When you get your Honours degree we
will pay you $180 a day (they were paying $155 at the time as I had only
completed 3 years of a 4 year course but had a teaching certificate and was
registered)
Early days of the PC and I had a copy of "Norton" winch at that time you
could actually get to raw data level.
Took me 2 days to drag every bit of text off the floppy in a sensible
readable order between the hieroglyphics and re wrote it to a new floppy
with a second copy as backup using "wordstar" (I think)
He was so happy he gave me $200 (GB Pounds equiv) and upped my pay to the
fully qualified level the following month instead of waiting 4 months for
the Hon's Degrees to be announced.
Can't do that with Norton any more.................
Sir Hugh of Bognor
