need Info on Cirrus card set in a PDP8/A

[Jerry Wright]

Hi,


I have a PDP8/A with a Cirrus   processor card set.  Either
I have looked in the wrong places or at least I have not
come up with any info. on these.  It has all the other
DEC cards M3320, M8416, M8317, M8417, Cirrus, Cirrus, Cirrus
and a M8330.

I'm trying figure out the console port (serial). It has the
standard  DEC port and 2 connections on the cirrus boards. The
cirrus  boards have there own ROM's.   It seems to start up and
do a auto boot of some type. It does not respond to the front panel
like a standard DEC board set does And there is nothing at the DEC
console (serial) port.  It does display what its doing. (addressing
and the the run light ) On the front programmers console.


Thanks,  Jerry
