The small board is an NVRAM or Flash memory board. I know the form
factor is right for the CSC-MC NVRAM board and wrong for the CSC-MT
which is a full MCI bus card, but I don't know about the CSC-M or the
CSC-MC+ (see

aecd8029d3ed.html>)
It would be odd for it to be a CSC-MC because the ENVM board holds the
NVRAM for AGS+ systems.

Not sure about the second #3 but #1 and the first #3 look like software
corruption of some kind.

The 6*ethernet card (CSC-MEC) is a cBus card and has to go in slots 5,
6, 8 or 9 with the CSC-CCTL2 board in slot 7. The MCI bus runs to all 9
slots, the cBus only the bottom 5. There are also two versions of the
cBus and if you've got really old kit (unlikely with CSC/4s) you have to
make sure that all the cards are compatible.

Flash, eh - that might well be a CSC-MC+ card then. We got rid of our
AGS+s around 10.3 so I don't know when flash started to be supported or
how to use it on that type of system. We always used to boot from ROM
or by TFTP. What do the boot commands in the config say?

ISTR it being 3 and them looking like standard AA NiCds. I have no idea
if they could be replaced or bypassed, but the point is that they're
there to preserve the NVRAM contents while the power is off - using a
UPS seems like overkill!

You have to install the CCTL2 and the other boards in the right slots
but there's nothing else to configure on the CCTL2. (There are DIP
switches to set a "unit number" but I can't remember what they're for
and the manual I have (Hardware Products Installation Guide, October
1990) doesn't help, and anyway it only covers the CCTL not the CCTL2).
