Rise and fall time of TI 'F' family

[Joerg]

Hello NT,

I'd like to upgrade mine too... How do you open the head? Does the port
labelled 'mouth' take CD or DVD? ...

A slice of wonderbread?

If you dont want to play that game, stick with an older less bloated OS
and non bloated apps.

That's the thang ta do.

Regards, Joerg

Hello Bob,


My father worked on the design of a system that had 2K of memory and
controlled a complete cold-rolled steel production line. IIRC it never
crashed. Probably around the time Bill Gates was in first grade.


One technique is simply not to upgrade. I am writing this on what some
would consider a clunker. Pentium 2, 64MB of RAM, old NT. Mozilla seems
to have some memory leaks so once in a while I have to re-start and it
speeds up again. But not more often than once a day. You can kind of see
when it's time because it starts grinding on the hard disk page file too
much. This is the machine I use to keep online data sheets on screen
while designing on the other PC.

I just don't follow the bloat unless there is a very compelling reason.
The only reason I can think of is if some SW isn't backwards compatible.
However, I tend not to buy such SW so only a client requirement could
trigger that situation.

Regards, Joerg

Armco Steel built a computer controlled hot strip in Middletown
Ohio. It opened in the early '60s and was controlled by a computer
supplied by Westinghouse. It had a 36" 10 MB hard drive that took over
five minutes to come up to full speed. It ran on 208, three phase. The
disk drive motor was 2 HP. The system was in use until the mid '80s
when they replaced it after it started causing problems, and they had no
real source of spare parts.

Remember those Phoenix 15" drives with the removable pack that went in
over the fixed disks? Had to be run on purge about an hour before you
*dare* load the heads?

4" voice coil and the head carriage on ball bearing rollers - great to
watch doing a butterfly test.

Puny by comparison with your beast, though, only a 1/4 HP motor

About 300MB, IIRC.

Some of those were still in use in the mid -1990s

Remember them? I scrapped truckloads of the old 20/20 drives with 20
MB fixed and 20 MB removable. I still have a big box of the magnetic
couplings from the scrap disk packs. The magnet assembly is missing
from the bearing, but I am building a wire measuring machine using an AC
motor with the magnet for the supply reel, and a belt driven DC motor to
drive the take up spindle. A controlled DC current to the AC motor
will control the tension, or brake the reel if the wire breaks or runs
out.

The worst design I saw was an early Burroughs computer that was built
with what looked like a clear vinyl VCR cover that was placed over the
open drive. I was surprised that the disks weren't gouged, but it had
sat in storage long enough to have dust on both sides of the disk.
