I was playing around with my 48 tonight, and decided to explore the self test
mode. After pressing ON-D, I then pressed the MTH key. The 48 started
beeping and displayed:
ESD 210V 210V
|| ||
Does this mean it has been zapped with an electrostatic discharge of 210V?
It passes all of the tests as far as I can see. I think it did get a static
zap the other day.

This is a fast looping memory test which will halt with a checksum if ram is somehow changed. Its purpose was to allow us to verify that the 48 was not losing its mind when we zapped it. In addition, the test also displays the current status of the low battery indicators in the machine: the "2" indicates the battery in the card in port 2, the "1" is for card port 1, the "0" is for the main AAA's, and the "V" is for a "very low battery" indicator (loss of contact, or other such) on the AAA's. A bar under indicates the active state - obviously, you didn't have ram cards in either port, since it is telling you the port batteries a low... The first set of bars is the current indication, the second set is a sticky bit for each that is cleared when the test is started by pressing the MTH key in selftest mode, but remains set if the corresponding indicator was set even temporarily during the test. An interesting feature, but I think not generally useful. All the obvious and non-obvious disclaimers apply... Steve
