>Here is my list of HP-41 questions: > - I heard a rumor that fourth was available for it. Is this true? An extended Forth is available for the 71B (Forth with an additional floating point stack, strings, file-handling, communication with Basic [a Basic program can invoke a Forth word and access the Forth stacks, and Forth can execute a Basic command and invoke a Basic function, passing parameters and receiving the result on either the regular or floating point stack], a built-in text editor and assembler), but there is no Forth language for the 41C. > - What is the difference between the new printer that works with HP-IL > and the old printer that plugs into a module slot? The HP-IL printer provides several features not available in the direct-connect printer: "parse mode" provides word-wrap when printing text, output can be right and left justified or centered on a line, a full 7-bit ASCII character set can be accessed, in addition to the 41C character set, 41C barcode can be printed with the plotter ROM. The principal advantage is that it can be used with other products such as the 71B, 110, series 80 computers and future products supporting HP-IL. > - Does the plotter module allow you do make plots that use the full > resolution of the printer? The only way the plotter ROM module interacts with the printer is in printing barcode. All other plotting on the printer is done using column graphics; each column of dots requires one buffer location and the HP-IL printer provides 101 buffer locations while the direct-connect printer provides only 43. > - What is the lifetime of the printer's head? The print head on either printer is expected to print at least 20 million characters with no failures. > - What is the lifetime of the HP-41 now that HP has released the 71? The 41C has been discontinued, but the 41CV and 41CX will continue to be built and sold for many more years, and HP promises to provide service for at least five years after the product is officially obsoleted (we are still servicing HP-35 calculators). > - Does anyone make a case for the the 41 in which the stupid quick > reference card will fit? > - What sort of non-technical things do people use their 41's for? > I use mine as a $250 alarm clock/phone book/appointment book/memo > pad, etc. What other things do people use it for? The best way to get answers to these questions is to contact the PPC, the users group for HP calculators. You can reach them at: POB 9599 Fountain Valley, CA 92728-9599 They publish a regular newsletter including new ideas for using calculators, calculator programs, product reviews, user letters and general information, and also organize meetings all over the world.

#N:umn-cs:30300001:000:1132 umn-cs!horswill Sep 13 22:31:00 1984 Here is my list of HP-41 questions: - I heard a rumor that fourth was available for it. Is this true? Does it run in finite time? It sure would be nice to have a real subroutine stack. - What is the difference between the new printer that works with HP-IL and the old printer that plugs into a module slot? I am thinking about buying one of the old ones used for my CX, but the Univ. of Mn. bookstore only sells the new one now. I notice that the old printer does not print out the date and time on listings like the new one is supposed to do. Does the plotter module work with it? - Does the plotter module allow you do make plots that use the full resolution of the printer? - What is the lifetime of the printer's head? - What is the lifetime of the HP-41 now that HP has released the 71? - Does anyone make a case for the the 41 in which the stupid quick reference card will fit? - What sort of non-technical things do people use their 41's for? I use mine as a $250 alarm clock/phone book/appointment book/memo pad, etc. What other things do people use it for? Ian Horswill
