HP41CL newbie question

[rprosperi]

Until Sylvain is available (he may have updated his tutorial), there is a quite detailed step-by-step explanation available here:

Keep in mind this was a few months ago, so some small details have changed (e.g. the clupdate program is no longer 1.0.0, so would need to use the updated version number, the UPDAT ROM is now version 3B, etc.) but the sequence and flow are still the same.

A key thing to understand is the clupdate software is a server that, once run with --update option, will sit and wait for data requests; the actual update process (initially scanning and then updating) is controlled by commands on the 41CL.

Also, the updates you will need will be unique to your machine's age and configuration, so interpret the results stated in that walk-through accordingly.

If you will be doing a full update (a good idea), plan on spending a few hours for the complete process, and I suggest you start with a fresh set of N batteries in your 41CL. For 95+% of that time you don't need to do anything, just wait for the update process to proceed.

Good Luck
