>1. What is the ram capacity of the HP 48 and 95 LX?

Base memory on the 48SX is 32 KB, expandable with 2 128 KB RAM
cards for a maximum of 288 KB.

Base memory for a 95LX is 512 KB, not expandable.  RAM cards only
act as disk drives, not main memory.

I am running Turbo Pascal 5.5 on my HP95LX.  It supports overlays and
dynamic variables.  Everything on the 48SX is RAM based--overlays are
not needed.  Everything on the 48 is dynamic, more or less.

A cord. And Kermit software.

For the 95LX, it is 8088 assembly, you provide your own assembler.
Officially, the 48 assembly language is undocumented.  There are those
on this news group that do know how to do it, but 48 assembly is a pain
mainly because it is not a supported thing.

P.S. - For my 2 cents worth, the 48SX is a great calculator, but
programming large projects or using large amounts of data are not
recommended.  The 95LX has got more raw capability, is more expensive,
and also is more frustrating, because of its almost useable keyboard and
almost useable display.

If you want to do serious programming, wait for a portable Macintosh and
use MPW...
