IBM ThinkPad 320

IBM Type 5523

The IBM ThinkPad 320 is a 486SLC-based laptop that was released in May 1993, exclusively in Japan. This model was essentially just a 486 version of the PS/55 note M23V, which released 6 months earlier. The ThinkPad 320 lacks any internal pointing device. Officially, up to 10MB of RAM is supported, but a source I found says a 16MB module will work. The proprietary hard disk caddy is apparently the same as the one used in the ThinkPad 330C/CS, and the ThinkPad 550/555BJ.
