Thanks!

Anyway, before I get on with the FP memory issue I decided that it was more important to verify that everything I had lined up for the Falcon, i.e. monitor, speakers etc. all worked together.

Thankfully it works a treat...

The speakers I rescued from work last December seem pretty decent quality, sound wise, too.

I think that I may even get around to starting on the Apricot FP CPU board tomorrow. I did get my (dwindling) stock of 16pin sockets down from the loft this evening.

Well, no Apricot repair today.

I had an e-mail at work asking around if anyone could help recover some data of a DDS-1 DAT tape (scientific data) written on a VMS machine. Well, we have an old DAT drive on a shelf at work and I have old Sun SPARCstations here, so I offered to help.

To cut a long story short, my workbench is now home to my SPARCstation IPC.

Oh, and I tried to get NIS working better on my home server, so I rebooted it... And GRUB now crashes out, so I'm going to have to fix that first.

*sigh*

Down the rabbit hole we go!

I got tired of rabbit holes, hence my multi server Windows domain is no more and I will never do it again. The worst part was recovering Exchange whenever something went down, bye bye weekends.

Well, it seems it's a bug in Grub2, which is fixed in a version later than the one used in the distro (which doesn't help me), where with newer xfs filesystem versions the loaded miscalculates offsets in the data structure and hence reads garbage. So, basically unsolvable.

So, I'm having to rebuild the root filesystem as an ext4 one and rsync the backup copy over to the original. Then I can attempt to re-install Grub2.

Well, the kernel boots... But that's as far as it gets. I think I'm going to gave to rebuild the initrd.img with the new fstab.

Got it working. Phew!

And for tonight's trick...

Extract files written on a VAX/VMS system stored on a DDS-1 DAT tape 30 years ago using a Sun SPARCstation IPC running SunOS 4.1.4 for a professor in another department...

My goodness! I'd forgotten just how slow tape drives are!
