Hello Avi Its a lot of work. Basically I matched the ram upgrade module port to a standard 144 so-dimm pinout. So I believe a standard 60ns sodimm module can be used to increase ram. So I have a old 32MB libretto module. What I am doing is first removing the chips an the board then connecting so-dimm sockets to the module using 32 gauge stranded wire. I am soldering the wire to where the chips were soldered and to the socket itself if need be. Once that is done I am going to run the socket into the hard drive bay and fix it to the side. the pinout for the libretto ram port is in the Libretto 100 maintanence manual. john --- Avi Cohen Stuart <[EMAIL PROTECTED]> wrote: > Date: Mon, 29 Oct 2007 06:01:26 +0100 > From: "Avi Cohen Stuart" <[EMAIL PROTECTED]> > Subject: RE: [LIB] speed gain using flash card > > John, > > I am very interested in the technical details on the > >64MB libretto > upgrade. > I don't mind to experiment but currently don't have > a clue to do what... > > Avi. > > > -----Original Message----- > > From: John [mailto:[EMAIL PROTECTED] > > Sent: Monday, 29 October, 2007 0:03 > > To: Libretto > > Subject: Re: [LIB] speed gain using flash card > > > > Date: Sun, 28 Oct 2007 16:01:36 -0700 (PDT) > > From: John <[EMAIL PROTECTED]> > > Subject: Re: [LIB] speed gain using flash card > > > > > > --- Philip Nienhuis <[EMAIL PROTECTED]> wrote: > > > > > Date: Sun, 28 Oct 2007 09:51:48 +0100 > > > From: Philip Nienhuis <[EMAIL PROTECTED]> > > > Subject: Re: [LIB] speed gain using flash card > > > > > Hello Philip > > : > > <snip> > > > > getting with a standard hard drive.
