Hurrah! Progress!
Your machine runs android 1.5 and the list of apps includes Tape-a-Talk Voice Recorder. I just tried this and it does make and store consecutive recordings.
Recordings are stored in the tapeatalk_records folder or can be accessed using the Tape-a-Talk icon. Records bear numeric names yy-mm-dd-hh-mm-ss.wav and can be renamed.
