The extreme III and IV are opproximatly twice and three times as fast as the II so if I would get another increase if I upgraded to one of those. I am getting 4 MB as opposed to 1.5 to 2 with the hard drive. I should expect 6 and 8MB with the extreme III and IV. AFAIK (based on a vague reminiscence and a google search) the theoretical maximum data transfer speed on an ISA bus is about 6 MB/s. As the Lib110's HD is attached through a 16 bit ISA connection (without DMA), that 6 MB/s is about all you'll get. Or am I wrong here? (hopefully not, for your sake) I am also using a second flash card for a virtual memory drive but it is an old one so only gives hard drive speeds. If I updated that with a newer one I would think the increase in speed be noticalbe in swap file use. How did you connect that 2nd one? thru the PCMCIA slot? I remember I found an external -PCMCIA, or rather, Cardbus- HD to be clearly faster than the internal one (I had a 7200 rpm Hitachi inside). There was also a thread on this in the mailing list. I notice a real reduction in temperature also using a solid state drive. My libretto was always having to slow down to cool off but it is very cool now when it runs. Anyway it all sounds like a bright idea to me. Any idea about battery power savings using flash rather than rotating storage? Sometimes I feel a bit sorry to have decommissioned my L110; it merely serves as a sort of book stand, right on top of a much older DEC 450SLC/e notebook (with a 50 Mhz 486-DX2 inside - wow). Sometimes I start them up just for fun, like today when the clocks in my place must be reset to winter time. BTW have you ever had any luck upgrading the RAM beyond 64 MB? (I remember you were busy with that). There were some guys who have fitted a Portege 64 MB module in the extension slot to get 96 MB; that was the max I've ever heard of w.r.t. Lib110. Best wishes, Philip

I am going to solder the buss to a couple, maybe three, of so-dimm sockets. I am going to run the so-dimm sockets into the hard drive bay, where I have room now (I was just waiting until compact flash capacity got large enough to use as a hard drive so I could try this and have space inside the libretto), and try using standard so-dimm edo plug-in modules. It is slow going because I don't have anywhere to work and lack tools. I don't think I'll have to remove the soldered chips on the motherboard. I have also been thinking of installing a sdram controller and use sdram but all of that is very hard to do since all I have is the memory upgrade port to use for access.
