Do the RAMcards used in the Ultralite conform to industrial RAMcard
"standards".  I learned sometime ago that many US and Japanese companies
formulated a RAMcard (or RAMdrive) standard to promote their wide use.
The Poqet uses the industrial "standard" RAMdrive.  1 M Poqet RANdrive
still costs around $500.  So if these RAMdrives are compatible, the
2 M Ultralite is a good buy just for the RAM alone.  Any comments?

I have been using Toshiba T1200 and T1000 for more than 3 years and
Poqet almost a year, so far I have lost any data yet.  May be I am
just lucky.  I have not had a chance to use my backup discs yet.
The RAMdrive has its own battery.  My calculation indicates that
the battery life is about 6 months.  Howver, if they are in computer,
the main battery supplies the power.  I still have the original
battery in the RAMdrive which has been in use for one year.
The same is for the Toshiba's RAMdrive.
