Great ! nWAIT may be a candidate for a pull-up. nWAIT has risen to
fame in GTA02 as the Glamo's preferred way of hanging the whole
system. In GTA01 it only connects to a test point, despite the 2410
manual saying
| If nWAIT signal isn't used in your system, nWAIT signal must be tied
| on pull-up resistor.
nWAIT can be ignored by software and is disabled by default, but
letting inputs float is rarely a good idea.

It already helped find one ;-) Thanks !
