	Here's one for the books...
	
	We've got a Vax750 that when powered up doesn't
	output ANYTHING to the console port. Ever board
	in the 750 was replaced with another set
	and the problem is the same.

	Problem with the console port you say? Well, the
	console on the 750 is strapped right to the back 
	of the backplan of the 750. And get this, the pins
	on the console port are:

		Pins 1,2,3, AND 24??????

	What is DEC doing with pin 24??

	We've got a TrueBlue digital vt100 on the console,
	tried every baud rate there is and still nothing.

	I've check all the power points coming from the power
	supply, everything looks ok.

	Something strange, I was told that the FIRST thing the
	750 does when powered on (along with printing >>>) is to
	try to boot off the TU58 if there is a tape in. Well,
	the TU58 tape drive is as dead as the console.


	ANY HELP would be great! I've been working on this
	problem for 2 weeks now, and NOTHING!!! ARG!!!


		thanks!
