Connector type on a IBM AC ADAPTER-30?

[marinelayer]

Hi everyone,

I'm looking for a 60W version of the IBM AC Adapter-30 (PN: 84G2128) ubiquitous to the 3XX and 7XX series Thinkpads. Why a 60W version, you ask? Well it's for a precursor to the Thinkpads; the IBM PS/2 CL57SX. From what I can tell it looks to have the same 4 pin connector (and pinout).

This may be a situation where I have to canablize a Adapter-30's cord and soldier it to a. 60W power adapter, but I'm hoping for another solution.
