All,
I've added a VCB02 card to my MicroVax 2. Right now the VAX is setup with
the following layout...
Slot 1 KA630-A CPU M7606AF
Slot 2 8M RAM M7609-AM
Slot 3 8M RAM M7609-AP
Slot 4 CMD SCSI MSCP encapsulating (top half) empty bottom
Slot 5 M7516-YM (ethernet, top) M7546 for TK-50 (bottom)
Slot 6 VCB02
Slot 7 VCB02 Memory
Slot 8 VCB02 Memory
Per the docs on bitsavers, the VCB02 can go in any QBUS slot 5-8, but the
layouts in the manual are different than what I have setup.
With the VCB02 in there POST takes longer, but the console still comes out
on the serial port. The VCB02 shows 3 red LEDs.
I assume I need to set the addressing on the card, but I have 0 clue what
to do.
OK, when you boot, you get no display on the screen?
That means the boot ROMs in your CPU board don't have
VCB-02 support in them. (Same as mine.)
My notes show the device address was set to 777402
(Gee, that looks like an octal address. So much I've
forgotten about VAX stuff...)
I think the 3 LEDs come on at power up, and then go off
in a quick sequence when the device driver configures
it.
Is this a VMS or Unix-derived system? I know VMS
4.7 had the drivers for the QDSS (VCB-02), but if you
are using an older OS, not sure.
As the boot ROMs don't support the frame buffer, you
should not expect any display until the OS is up.
Other than making sure the I/O address was set to
a value so that the driver enumeration could identify
the board, I did nothing special to configure it.
