Looking through some of the Japanese sites, I came across pictures of the ADTEC a while back. The physical layout of the chips on the silicon is a little different. If memory serves me, the ADTEC had less on there. The Vintage chip, after looking through the List archives, seems to be a Toshiba part. Maybe for their line of Libretto laptops, before the became a bit larger? I couldnt find any technical information on either, such as speed, voltage, etc. Maybe I could find some type of Classic RAM analyzer? Anyone know what specs are needed for 2400c RAM? Never could understand why there is a *hardware* limit on the RAM in these units.... Hmmmm... next up is soldering a 64MB chip into it ~_^ __________________________________ Do you Yahoo!? Yahoo!
