Unfortunally the files are way too big to send over mail, but I've made them available from our webserver, here you go:|
It's all the available updates, at their latest versions. Heads up on the 2238C NIB firmware, there were one version 4.13.1 released 3-2-2004, and another version 1.03 released 6-4-2005. Don't know which one you should use, I thought it was a bit strange the lower number version was released later...
The memory card explorer demo software is packed with the 1224C.
Best of luck!
