HP-41 Math/Stat Pac? - Karl Schneider - 07-17-2002 I've seen a "Math/Stat Pac" ROM included in various 41C* auctions. This module is listed in a 1987 HP calc accessories brochure, but not in the HP-41CV accessories flyer from 1982. The Pac's manual has not been scanned for the MoHPC CD set, to my knowledge. Q: Does the Mat/Stat Pac include *all* the functionality comprised by the "Math I" and "Stat I" Pacs available in the early '80s? (I have both of these, with manuals.) Thanks,
Karl

Re: HP-41 Math/Stat Pac? - Raymond Del Tondo - 07-17-2002 as thibaut.be already wrote, you'll have the whole functionality of both modules.

Re: HP-41 Math/Stat Pac? - Chris Catotti - 07-17-2002 The MATH/STAT PAC for the HP-41 comes with the Math Pac Manual, The Stat Pac Manual, and a card 00041-9056 "ABOUT THIS PAC AND ITS MANUALS" that says there is no seperate manual, just use the two manuals, You can not just solder a MATH PAC and a STAT PAC together, you would get a port conflict. You can solder one application ROM with a system addressed ROM, such as TIME MODULE, EXTENDED FUCTIONS/EXTENDED MEMORY, EXTENDED MEMORY, QUAD MEMORY, HP-IL, etc.
Combining HP41 ROMs. - Tony Duell - 07-17-2002 Actually, although the Math/Stat Pac contains the same code as the separate math pac and stat pac, you can't just solder the 2 PCBs together to make the combined pack. To understand why not, you have to know something about the HP41 memory layout. The Nut CPU can address 64K words of ROM. By convention, this is divided up into 16 4K pages. The first 8 pages (0-7) are used for 'system' functions -- the HP41 firmware itself, printer ROM, HPIL ROM, Time module ROM and service module. Re: HP-41 Math/Stat Pac? - Raymond Del Tondo - 07-17-2002 Of course you're right regarding putting (or better not) the ROMs together. I simply forgot these port-coding mechanics while writing the article. Maybe too long ago since I fiddled with modules;-) Regards,
Raymond
Re: Combining HP41 ROMs. - Mike (Stgt) - 07-19-2002 You should not put the Card RDR ROM to an other page than E. Ciao.....Mike
BTW, this list was obviously scaned for email addresses as I received spam to "Mike (Stgt)". The addition 'Stgt' I only use on this list to show my location. M.
Re: Combining HP41 ROMs. - Tony Duell - 07-19-2002 Well, the physical ROM in a 41 card reader is an 8 pin chip that will _always_ appear in page E. That chip has no pins to select which page it would appear in. Re: Combining HP41 ROMs. - Mike (Stgt) - 07-23-2002 Not only in an MLDL it would fail, in an SW emulation too. If you look the firmware listings (VASM, MCode) you see at once, that far jumps (Go To/Execute - on Carry/on No Carry) are normaly coded "port independent" with 3 10-bit words (by calling a appropriate Main Frame routine with a relative address where to go realy). All 2-word GTO/XEQ in the Card RDR ROM go directly on page E. Ciao.....Mike
BTW - who is reading along VASM listings anyway <VBG>
Re: HP-41 Math/Stat Pac? - John Breda - 08-01-2002 I believe it does. I would like copies of your math and stat manuals however since I have lost mine. Are you willing to help? jbreda@massmed.org
Re: HP-41 Math/Stat Pac? - Ellis Easley - 08-01-2002 Are you aware of the Museum CD-ROM set? It includes scans of manuals for many HP calculators and accessories including the 41C Math Pac and Stat Pac. Here is a page with a list of the contents:
