I have seen a host of chess computers being offered for sale where the adaptor is missing.  Otherwise, the unit is in beautiful condition with all pieces etc.  Someone obviously took great care of the computer.  But in alot of cases it is useless without the adaptor. This is something you would not loose.  Why are so many missing?  Is it possible that the seller is truly unable to test it, thus saying it works perfectly as far as he knows?  So if it does not work, you are sol.

Of course, not all chess computers can work on adapters, but I suppose that's not the kind you have in mind.

So restricting ourselves to the sort that can be connected to an adapter, I've seen quite a few computers that came without an adapter. If a computer also works on batteries, the supplier can keep the price low by supplying the adapter optionally. In that case the customer can try to use a 'generic' or 'general purpose' adapter.

I remember I once bought a new Glass Chess computer from an American seller. Excalibur had obviously economized on the adapter: there was none in the box and if I ordered one in America, it would not only be twice as expensive as a general-purpose specimen, but I would have to pay a large sum for the shipping as well. So I tried a general-purpose adapter which I had at home. Little did I realize that the manufacturer had even economized on parts. If the manufacturer had used a diode (which is not exactly a very costly component, is it?) to prevent current flowing through the computer in the wrong direction, my Glass Chess would still have been intact (http://overtom.nl/weblog/01DEC04.html)

Anyway, it's not sure at all that all the computers that are sold at eBay without adapters were originally bought with an adapter.

As far as I know, computers that need a special adapter (such as the Milton robot) are normally sold with one, and if the adapter is absent, you may expect a considerable discount (my MB computer came without an adapter - and with no manual - and cost no more than 35 Euro).

And if you can use a general-purpose specimen, please be smarter than I was and don't expect all manufacturer to protect their computers from reversal of polarity.

Best regards,

tom
