I found these and cabbed them up together. I did not write the exe's, but the installation called for dropping them in the startup folder. The attached cab installs them to \Program Files and installs lnk's to \Windows\Startup.
The meters are pictured below. The bar at the top of the task bar is
battery remaining, and the one below is free
RAM.
Install the cab then soft reset. Each
meter uses 1kb of prgram
memory
