According to the brochure I got this afternoon, the _only_ difference is that there is 32K memory, rather than 2K (discounting cosmetic differences -- it now says "Advanced Scientific Calculator" on the panel above the display. >2.

When I talked to the EduCalc people, they said that HP was still having the yield problem, and that they (EduCalc) already had a backlog of orders, but expected them to start coming in around the middle of February. When I talked to the guy running the calculator desk at the Tam's Stationers near San Diego State U., he checked his distributer and got a date around February 1. No fool, I filled out a special order form to get notified as soon as they come in. -- Sean Malloy {hplabs!hp-sdd, akgua, sdcsvax, nosc}!crash!malloy ARPA: crash!malloy@nosc Naval Personnel Research and Development Center San Diego, CA 92152-6800 UUCP: {hplabs!hp-sdd, akgua, sdcsvax}!nprdc!malloy ARPA: malloy@nprdc

There are a number of differences between the HP-28C and HP-28S. Here's a brief summary of the modifications/enhancements present in the 28S: * 32 Kbytes of RAM * Directory system for USER menu * Custom menu in which you can combine user variables and built-in commands. * Save, retrieve and combine LCD pictures/plots. * Combinations and permutations * Plotting continues despite math errors/exceptions. * POS (position) finds an object in a list. * A(I) returns the Ith element of a list or array, within an algebraic, allowing indexed variables. A(I,J) works too. * User defined functions may be defined with programs. * Command arguments requiring real numbers in lists permit use of programs or symbolics in place of the numbers. * Double-space print mode available. * Programs decompile and print with automatic indentation to show control structures. * Single character operators automatically add needed spaces in program entry. * Press ON-L together to dump LCD image to printer at any time. * RND (round) works on complex and array objects. * Singular matrix inversion is tied to the divide-by-zero exception flag. * Errors automatically identify the guilty command. * Various 28C bugs fixed. * Other minor tweaks.

Do you know what price EduCalc will be charging, or is that also up in the air?

Its wonderfull to hear that the 28S fixes the bugs in the 28C and that its lots faster, it would be even better to hear about how to trade up. The release of bigger/faster/fixed so quickly leads me to hope that it will be possible. -- Dale Chayes Lamont-Doherty Geological Observatory of Columbia University usmail: Route 9W, Palisades, N.Y. 10964 voice: (914) 359-2900 extension 434 fax: (914) 359-6817 usnet: ...philabs!lamont!dale

Since I have gotten many requests for the address of EduCALC, here it
is:
EduCALC Mail Store
27953 Cabot Road
Laguna Niguel, CA 92677
Orders can be placed by calling 1-800-633-2252, ext. 345. If you ask
them to put you on the waiting list for the 28S, they will take your
credit card number; then, when the calculators come in, they will charge
your account and ship the calculator to you. Again, the price for the
28S will be $179.95 from them. The price for shipping via UPS is $3.00.
