Hello All, Somehow the question was quickly forgotten or ignored and the discussion soon deteriorated. I have a 1GHz MDD SINGLE processor with a 133MHz bus and would like to know if the following item on eBay can be used to upgrade my MDD. TIA, Dan http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=5797912059&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1
