Hi Mike,
The Bernoulli disks definitely do use servo, so as you say, if the servo
patterns are damaged the data is toast.
Do you have any advice on head cleaning? The docs on the second-generation
drive (Alpha-10H) just say to use a cleaning cartridge, and I don't have
one. I've cleaned floppy dr
I'm glad you corrected because when they worked, they were awesome. When
they didn't, life had a lot of swearing in it... And when I was sysadmin
for the MicroVAX II that had them, I swore like a sailor

If it is anything like installing NetBSD, which I have done on a
VAXstation with a DLT4 drive, it should be 512 byte.
So, while I do not know for sure for Ultrix and MicroVAX, 512 is
probably a good starting point? Hopefully someone else will *actually*
know.

Be careful, TK-50 is different than 9-track. It's a streamer tape like
QIC, 4mm and 8mm. The blocking is done under the covers by the HW and the
blovk size if just how a DMA is done. I recommend that you pre-fetch the
read with dd or double-dd setting ibs=64k, obs=20b and conv=sync and pipe

I can confirm that the media is starting to degrade - at least, it
does if it wasn't stored properly. I have a couple of cartridges here
that are shedding badly. You can manually open the cartridge by
tripping the catches and sliding the door open, and look at it. Here's
a picture of such a sheddin
Hey all --
Got an HP 2382A terminal I'm attempting to resurrect. I get no video, no
heater, no high voltage. What I believe to be the horizontal output
transistor appears to be bad, but I'm not sure if this thing contains
internal diodes that might be throwing off my testing attempts. It's
