   Are there any figures available from HP on how many HP-48SX units
have been sold? Or better, is the info gathered from the customer
survey `purchase registration' cards available?

How many units of the HP-41CV emulator card have been sold?

   Are there any second-source ROM card manufacturers? What is the
cost-quantity/turnaround for HP-manufactured ROM cards? I guess that
here voltage regulation isn't as much of an issue. Are the ROM cards
some kind of standard PROM modules - can I, with the proper equipment,
program the ROM cards myself, or are they manufacturer-masked?
