I was wondering if anyone knew where i could get a processor chip for an old ibm thinkpad i found laying around and how much it will cost me. I want to put http://menuetos.org/ that OS on the comp and maybe put a little use to it.:alright:

What model of thinkpad, what processor, what speed ? Have you tried IBM service parts, they sometimes have older ones around. I find that I have no problems finding parts for my 2647 A2U T20 from IBM, though that is a PIII 700 Mhz so it might be a bit newer than yours.

do you think Dell can upgrade my 25MHz 386SX laptop circa '91? :grin:

Nope, but then he didn't describe anything about his laptop except that it was old, I see my T20 laptop as old. If it's a PII or above the chances are good the IBM can still supply the parts for it. If it's a pentium there is a small chance all the same, below that no chance at all.

Hurrah! my P200MMX still has hope :) not that it's useful "on-the-go", since the batteries are expensive to replace and the ones i have go kaput after about 5 mins.

Yeah, I have the same problem, batteries are expensive. Mine can still last about an hour and a half but that's down from 2 1/2 to 3 when I bought it.

okay well i took some time to examine it.

on the inside of it when you open it up in the lower left hand corner of the by the screen it says "720c"

and on the back of it along with some other information on this label it says "version 9552". As for the processor speed anything that'll get it to run not a 60mhz or a 2 ghz just something low maybe like a 400mhz would do.:alright:

This is the info you need :

720c Harware Maintenance Manual

It should give you the part numbers you need to check with IBM. That model was made in the early 90's so I wouldn't hold my breath. BTW it's a 486LC 50 Mhz Processor.

ouch, okay thanks and i guess i'll have to toss this crap...

Still ok for DOS :) and the processor should be about a buck or less.

thats cool i've been wanting to work with a dos only environment for a while.:grin:

and my Dad thought that the chip was gonna cost alot of money... he swears he knows more about computers than me although i put my own together when i was 11.

thanks again:alright:

hmm... well, i've never assembled my own computer... my father always has. but i've been programming for over a dozen years. although i make no such claims about knowing stuff about computers, it's assumed by a lot of people that i do :rolleyes: .
