IBM Thinkpad 730T
I had a lovely IBM Thinkpad 730T on the shelf for ages and actually forgot I had it. It's a very similar machine to the 730TE, so all the teardown instructions and ideas to replace the 8 leaky caps and the soldered coin-cell battery are exactly the same. What was especially charming about this 730T was that it had the original 105Mb IBM PCMCIA miniature hard drive, running Windows For Pen Computing, fully working. I found a compatible (parity) 8Mb IC DRAM card, put a new energiser 2032 battery in, and we were in business.
The only difference between it and the TE is that it has a much slower 33Mhz 486 without a maths coprocessor.
