IBM ThinkPad 700/700C
The ThinkPad 700/700C are 486-based laptops that were released in October 1992.
The ThinkPad 700 and 700C were really the first "true" ThinkPads. The 700T came first, but it was not actually a laptop.
These ThinkPads, along with the 720, are weird beasts. They are based on IBM's Microchannel architecture, not ISA, and they use proprietary ESDI hard drives. This means that getting one working can be really difficult if the drive has gone bad. I currently don't know of a single modern replacement for them, so your only option is to get another ThinkPad and hope it has a working drive in it.
The systems shipped with 25MHz 486SLC processors, with a 50MHz 486SLC2 upgrade being made available later on. They were also available in a beige color, I believe only in Europe/Germany?
These models were badged under the PS/2 brand name. Labels on the inside read "700 PS/2" and "700C PS/2".
