I have a DecStation 5000/200 running 1.4Q.
This machine crashed. OK - no big deal I thought ...
But then it started:

I have a serial console only. This worked fine all the time.
But now I have only the output from the boot process until it
says abount a filesystem, which I should check manually ant it asks
me to press ENTER or to enter the name of a shell.
At this point I noticed that the serial console would not take my
input - it simply ignores it. So I cannot do anything, not even
interrupt the boot early with a CTRL-C.
First question:
Anybody seen this? Do I have any chance to make some input?
I have removed the graphics card already - no difference.
I have a DEC keyboard and treid this - no diffrence.

At this point I decided to trie to read the SCSI disk on another machine.
But the only one I have is a Linux PC running a 2.2 kernel.
It recognizes the disk on startup, but says:

 sda: unknown partition table

And if I try to mount e.g. /dev/sda1 it complains

 /dev/sda1 is not a valid block device

So this got us to the second question:
Do I have any chance to recover my data mounting the disk on Linux?

Thanks for any suggestions,
