USB41 while upgrading the 41CL

[aurelio]

Thank-you Sylvain, while the CL's update is running I'm rereading the old posts and really I should have done it it before to ask, I must flash my own memory to get an update for myself

I have done several update cylces with >200 ROM images to be updated on a single set of batteries, and then used it often for weeks after that, all on one set of batteries.

I keep a new set of 4xN batteries ready nearby my work area, but I would not expect to need them for just upgrading 2 machines.

You might even want to hook up your 41CL via a USB power module to a permanent power source during update. The idea is by Diego Diaz. Find the schematics to build one here: http://www.hpmuseum.org/cgi-sys/cgiwrap/...722#183722 You will need a doner HP-module for it.
