Security & Theft Securing tractor from theft

[patrick_g]

Won't be long before the rs232 is nothing but a bit of data and old specs .. something you will find in a history book...

You mean like REAL floppy disks which were 8 inch?

Note for youthful readers: 5 1/4 inch floppy diskettes started out with about 360K single sided single density.

REAL floppy disks (8 inch IBM 3740 format) had 251K storage and were single sided single density.

Probably more obsolete than button hooks for high button shoes.

In many cases I'm more concerned about securing my machines from vandelism than theft.

Funny you mention those 8" disks. I had a dual drive set, back in??89-91? they were old iron even then.. I used an external floppy controller and 'driveparam' from ms-dos to make those things work. I got them from a salvage sale from UF along with a box of disks... useless devices.. but was a fun make-er-work project.

I bet it won't be long till usb and firewaire are about the only non video/audio IN/OUT ports on a computer..

On consumer PC's, you are dead on. On industrial PC's, you've got more than a few years left. Look up PC104, EBX other SBC computers. There's a whole 'nother world out there that a lot of folks aren't aware of. A lot of legacy stuff will be around for sometime to come.

The first removable disk I saw was about 14 inches across and was in the 25,000 dollar bracket for the unit. If I remember right the disk held a whopping 5 k of memory and we were so amazed

It is amazing what you can do with Industrial Programmable controllers. 15 years ago I worked at a steel mill a couple of years before I quit we put in motor controllers for some 750 horsepower motors. The old unit had all the servo loops in the controller ( speed, current, voltage etc) The new units did all the computations in the PC and then connected with the motor controllers with fiber optics so that it could handle the motors in real time.

Why would the average computer user here have anything other than a consumer grade pc?

in any case.. there are other applications where rs-232 use is still common. i have rackmount electronic gear.. new.. that still uses it.

My comment was aimed directly at the average pre-built.. box store computer... HP, Dell.. etc..

And from the peanut gallery:

The performer again leaps upon the boards. His cloak of many sides swirls about his ankles. As he strides forth dispensing "My opinion only is allowed" the cloak of many sides inadvertently grasps his prancing feet and deposits him face down in front of the lowly peanut gallery audience. Slowly, slowly he recovers his limited facilities and makes haste to the curtains for shelter from the diatribes of the lowly he rails against.

Being a duly relegated member of the peanut gallery can be interesting and does have benefits.

This thread started out about securing tractors from theft and now it's moved to floppy drives? Next it will be IBM selectrics and Royal typewriters----------creatively used as front weights.

I still got one of them old 8"floppy's somewhere, PDP11

EXCELLENT

Yes, being in the PG has benefits, low risk and high upside for entertainment opportunities.

PG, er ahh, I mean Pat_G

IM not a peanut if I am anything it is a full sized nut

Great Idea i am sure they can be bought cheaper than front end weights and probably about the same weight.

 

[Soundguy]

I got a couple setting in our office supply shed.. and yep.. they are some good dead weight.

I'll see your 8" floppy and raise you two complete boxes of 80 column punched cards (er.. actually unpunched cards)

OK... who's got punched tape??

 

[Soundguy]

Hey now.. food for a card walloper!

Got you covered. Contains a program to compute electric bills on an IBM 1620. 1620 was cabled to an IBM 1401 for meter read card I/O and mag tapes.

In the late '70s, I did a payroll system for a remote site on a 3741 with those giant disks. Dialup connection to mainframe to upload results.

[texasjohn]

Well, bless my little BCD heart.... there's a fellow who knows how to

1 read a card (from 100 to 179 on a 1401)
2 punch a card (from 200 to 279 on a 1401)

with a little word mark here and word mark there
an early card read here and early card write there
he knows how to get the best thruput anywhere

If some of y'all don't understand the above, it's OK... GS and I are in our own little world
