Re: [Thinkpad] CPU Upgrade for 770Z - Anyone Tried PIII 500MHz after Switching 64MB Onboard Memory to 100MHz?

Hi Brian,

You might want to check out ebay for those sticks you're
talking about. I just did and found two currently going
for $30 usd ~ just do a search there and include that it
also look in the descriptions with the text of "Fru#33L3069"
and "Fru#20L0255" ~ Just a thought if you're trying to safe
a few bucks. Just keep in mind that some sellers in the US
may not want to ship internationally, which in that case, maybe
get a friend here in the states to get them for you.

Just a thought
Justin
