They do The real problem with NiCd's is their power curve. Normal batteries follow a long steady line from 1.5V down. Nicads start at 1.2V, drop quickly to a level slightly lower and then suffer a very slow decline to ~1V or so. After that it just sort of drops away to nothing. Suddenly. This is really bad when your unit's memory could get wiped out. A computer's battery level alarm doesn't give a lot of warning and may not even trigger. BTW Henry, welcome aboard. In an earlier post you spoke of those right-shifted special characters. There is a nice keyboard template overlay you can buy. They should have included it with the base machine. -- Red Alert. -- Q, "Deja Q", stardate 43539.1 Arthur Tateishi g9ruhtra@zero.cdf.utoronto.edu
