Default Re: IBM PS/2 seems to have got stuck!

Unfortunately there is also a 8086 version of the model 30 as well as the 286 version you have. I am pretty certain that 61X8574 is the p/n for the 8086 version power supply, 27F4166 is definitely the correct psu for a model 30-286. The power supplies are also slightly different shapes and the power switch link rods (from front panel on/off toggle to the power switch on the psu) are also different lengths. I suspect the connectors are also different. Given the scarcity of replacement parts I wouldn't risk fitting the wrong PSU.

There is a seller on Ebay offering 27F4166, they are listed as being for an 8555 not an 8530 but don't be put off, I have checked and 27F4166 is also the correct psu for an 8555 (PS/2 mod 55sx which is the same physical size as a 8530 but is a 386sx microchannel machine).

My brain may unearth more information overnight, if so I'll update this thread in the morning.
