11/34a Thanx..

  Well, muchas gracias to Mr. Duell; I have one of my 11s out of
deep sleep and talking to it's console. For any who have followed
this sequence.. the problems resolved to a) bad BA11 (PSUs good,
something else is wrong) b) the old grant continuity confusion, and
finally c) a bad RS232 cable I put in the line to the console VT100
to extend it a bit.

  So now, I have one 11/34 computer running, with an RX02 (but no
bootable media for it) and two RK05s, neither of which work at the
moment.... but that's the next hurdle.

 Actually, I have configured a single RK as unit 0 and terminated
it. The *problem* is something in the control logic preventing the
unit from spinning up the disc and coming into ready. So I'm
kneeling on the floor under the drive with a voltmeter and a scope,
trying to find where the chain is broken. At least I have extender
cards....

  Again, many many thanks to all of you who have taken the time to
offer advice... it was correct and successful.

  More later as the situation progresses..


Cheers

John
