compatability of ac power supply ?

[parangles2]

Can someone give me a general idea of which older thinkpads use
a common power supply connector?
I am thinking of buying a cheap T61 to use as a dedicated iTunes machine in my garden/ BBQ area.
Most of the cheaper T60, 61s on eBay have no HDD or power supply
and I would like to use stuff from my 600x and T41 T41P scrap heap.
Thanks

I believe it's T6x/X6x/Z6x when Lenovo went to 20V power supplies with their own triaxial barrel connectors (metal shell on the outside, metal shell on the inside and a center pin). Earlier to this, was the ubiquitous 16V yellow-tipped coaxial plug. They are not compatible. Put another way, all of the 600X and most of the T41 stuff can't be used with the T6x. Besides the AC adapter, this also applies to the memory and hard drives. You should be able to swap the T41 Ultrabay Slim devices into the T60/T61 however.
