[comp.sys.next] NeXT memory questions.....

dwboyce@acsu.buffalo.edu (Mr B) (02/16/91)

I have a couple of questions concerning the new NeXT's and memory.

1) What is the difference between normal 1MB & 4MB simms and the
interleved version the NeXTstation Color requires? And are there any third
party suppliers of this????

2) There were comments when the NeXT was first released that, although it
used 1MB simms, 4MB would and possibly 16MB simms might work in the NeXT.
Since one company selling 16MB memory was memtioned on this net has anyone
tried to use 16MB simms????

The interleaved memory used by the NeXT color products (both
Nextstation and allegedly nextdimensions) are in a 72pin packaging
and are 80ns or faster.  They come in 256Kb x 32 or 1Mb x 32 for
non-parity  and 256kb x 36, or 1Mb x 36 for parity systems.  There
are third party memory suppliers investigating this memory, but
currently they have had space (side by side) problems fitting
their prototypes into the color NeXTstation.  If I hear something
definitive on the subject I will post the information.

BTW we will not post memory prices and suppliers in the FAQ. However
we will have pointers to such information if it maintained on
some archive.

Can you tell me if this is the same memory used in the Macintosh IIfx?
