RE: NEW: HP 15C Collectors Edition
Hi all,
Received my cable a few weeks ago but only just had the opportunity to download the firmware to fix the HP16c mode DEC bug. Have been following the excellent instructions on the Calculator Store & everything worked as described by Jose. However, I am having trouble locating the memory addresses that need to be modified. Downloaded & installed free Hex Editor Neo for Windows but can't seem to find the following addresses: > At 0x0EF5E we find 46 03 - and this is not what we expected (346)! Then we remember that the coding here is "Little Endian" so all byte nibbles are reversed - so it is correct! We need to replace the 46 03 by 00 00. > At 0x0EF60 we find CB 01 - which is the Little Endian 2-bytes form of the 10-bit number 1CB. We need to replace the CB 01 by 00 00 > At 0x0EFB0 we find 7A 01 - same as above, this is the Little Endian form of 17A. We need to replace it by AC 03. I've only dabbled a little in the past with Hex Editors so probably just my lack of experience :-(. Would any of you please suggest how I might find the addresses within the editor? Thanks, Michael |
