Well I did some looking and I found that the 1mb apple SRAM models DID
work all newtons (PN: H0028LL/A). However, most of the flash cards, 2
and 4mb only mounted read only (PN: H0008LL/A, H0092LL/A). But one card
4mb apple card did work (H0230LL/A) and those had the white label I believe.

Other flash cards that are known to work in emates are:

INTEL Series 2+, P/N: iMC0nnFLSP where nn is the memory capacity in MB.
They came in 4, 08, 20, 40 MB
Reading voltage: 3.3V,5V; writing-/erasing voltage 3.3V,5V,12V.

INTEL Value Series 100, P/N: iMC0nnFLSC where nn is the memory capacity
in MB. They came in 02, 04, 08, 16 MB.
Reading voltage: 5V; writing-/erasing voltage 5V

Now if I remember right Viking has several cards that have those
voltages and will work as reported by several members in the past (look
for linear 5v reading and writing). You might want to dig in the
archives, or perhaps someone will speak up that know the particulars.

Or go for a SRAM card, they are not as common but any SRAM card will
work in a Newton. I have bought several over the years, but the are
usually more expensive than FLASH but don't have limited write cycles
like FLASH does. Is that a issue? Some say there is so many write
cycles that your great grand kids could be still using the same FLASH
without a problem in a Newton. Others say no. There has been several
debates in the past and you might want to check the archives.
