HJhook up a serial disk drive to your 128, press the reset and notice
if the LED on your disk drive comes on, then back off.  If it sticks
in the on position, then you may habe a bad reset circuit, 556 chip
and assoicated parts.  Dont rule out the small capacators in that
area, they have caused me problems once before!  Really tuff to hunt
down!
 
Also, check the power supply!  I know, evveryone says that, but it can
be the source of a lot of trouble!
