What do you think, will our old computers become valuable antiques of the future? Should I start seeking out a Win 3.1 system to make my fortune in the future?
Just an IDLE thought!No.That's my plan to be a billionaire scuppered!  If you had one of these it might be worth some money.

Interesting article on some of the history of computers.Do mechanical analog computers count?

Original IBM PC (1981)

The PC that started the whole craze almost 3 decades ago isn't worth much today, even to antique dealers. A Model-T Ford still gets a raised eyebrow of respect in Sunday parades, but the original IBM PC is worth less then a BRADY Bunch Lunch box.

Several owners have raised the price of their Originals by turning them into Lamps. 30 dollars each doesn't quite make up for the 10 thousand or so that was paid for each one, but that's deprecation for you. Besides, they save money they owuld have spent on a lamp for the side of the bed.

IBM XT:

A mega-improved version of the original. It took twenty engineering teams to design this new PC. They each won a award for engineering excellence when they placed a "reset" button on the front of the case. No longer did the users have to reach into the jungle of wires behind their PC every 15 minutes when the computer froze inexplicably! They were each given handsome bonuses and forced into exile, so that no other company would learn the secret engineering techniques involved with putting reset buttons on the front of the case.

owners of these PCs have also been able to create light fixtures from these old PCs. The most profitable (about 50 dollars) means wiring the reset button as the light switch. This makes a great lamp for the side of the bed.

Now, all that being said, there could be money in it yet! A GERMAN CALCULATOR from the 1820's fetched $11.8 Million at an auction at Christie's in London, a record auction price for a scientific instrument. How many calculators have you thrown away over the past ten years? (Including the free ones included with magazine subscriptions?)

The Altair, the first Personal Computer, is now selling for thousands of dollars as a collector's item.

Your IBM=PC, XT,286 or 386 would have to be passed down for several generations before it can be cashed in as a collectible. And your great-grandchildren will always remember you as a techno-weenie. But at least they might be able to live comfortably.I've heard that the old eight inch floppy drives and disks can be worth some money.I have a few OLD computers:

Acorn BBC Micro - 1981
Sinclair ZX81 - 1981 (I Think)
Acorn Archimedes 310 - 1989
Acorn A5000 - 1992
Ambra Sprinta (Windows 3.1, 486SX, 4mb RAM) - 1992

All still WORK!  BBC Micro is actually a hybrid of two broken ones - One had dead PSU, other had dead motherboard!

They can all (Except for Ambra Sprinta) can be found on Google.
