dm4l board on hicom300e

[tq7]

Hello,

I am using a Hicom 300e System with installed DM4L Board.
Does anyone know the meaning of the Status LED on the DM4L Board?

Our board has status LED named RUN (that's quite clear), Busy (I got that as well), LCT, NAL and UAL.
As far as I know, the LCT Status ist flashing, when the System is started without HDD.

What ist the meaning of NAL and UAL?

LCT actually stands for "Load (from) Cassette Tape," which happens when you push the LCT switch at start up. The ACT LED indicates hard drive activity, and the two LEDS at the bottom are for Minor Alarm (Left - amber) and Major Alarm (Right - red).

I think that covers it.
