Module codes Message #1 Posted by Matthias on 25 June 2003, 5:17 p.m. Hi again.. perhaps someone can help me once again.. I do want to get clother infos about the HP-41 module codes. Many of the modules do have a code as 8250xX-Xxx, but can you help me to disassemble this code? 82500A 4k modules produced by HP for companies? 82500B 8k modules produced by HP for companies? 82508 ? 825009 ? -Axx produced in America? -Bxx produced in Brasil? -Sxx produced in Singapore? Did I forget something that can be interesting for other people? Thanks to all, Matthias Matthias

At least he showed me some of those modules, including the Buderus ones, I think ;-) Raymond BTW: Since you bought a W&W surveying module some time ago, have you tried the software ? It was much work...

Re: Module codes Message #3 Posted by Ellis Easley on 28 June 2003, 7:13 p.m., in response to message #1 by Matthias In my 1986 HP catalog, under the heading "HP-41, HP-71, and HP-75 Custom ROM Modules", I find for the HP-41: 82508A/B and 82509A/B, "Provides 4K or 8K bytes of memory with each module, or nearly 21,000 program lines with up to 4 8K byte modules." Also for the HP-71: HP82491A/B through HP82494A/B, "Provides 16K, 32K, 48K, or 64K bytes of program storage in a plug-in module. May be used in quantities of one to four for a maximum capacity of 256K ROM. (Minimum order: 100 modules.)" And for the HP-75: HP82726A/B through HP82729A/B, "Provides 8K, 16K, 24K, or 32K bytes of program storage in a plug-in module. May be used in quantities of one to three for a maximum capacity of 96K ROM. (Minimum order: 100 modules.)"
