The actual drive is the TK50. There is a scsi bridge to make it a tk50z.

What are we talking about a tk50z in a ba42 box?

In addendum to my earlier message, can anyone point me at a source for
the pinout of the TK50? I did a websearch, but it was hardly productive.

I've picked up a TK50z-ga (TK50 in a box with a SCSI bridge card
inside)
recently. The scsi controller in my *c does see it, but the board/drive
doesn't return any id when probed. What I'd like to do is pull the TK50
and put in a TK70 (for anonther system, not the 486).
The question of the day is: Are the two drives interface compatible?
Thanks.....

OK, by *c I'm guessing you mean PC, or to put it another way a PC running
some kind of Microsoft OS. If this is correct I'd say you are out of luck.
I seem to rememeber reading a few months back about someone having limited
success getting a PC running Linux to access one, but couldn't get it to
function properly. I believe the problem is with the way DEC designed the
SCSI bridge.
The TK50 and TK70 require separate controllers.
Now the question of the day is why you would want to waste them on a PC
when you could attach them to a nice VAX! :^)

Is there any chance of getting a copy of the ROM on the SCSI bridge card? I've
got a TK50Z-FA, and have been trying to upgrade it to a -GA. I tried DEC
a while back, but the part number in their system shows zero availability.
When they had them, it was a $4 part.
I'll show you mine, if you show me yours. :-)

I just did it this way:
Linux on PC, RT-11 on PDP-11/83's MFM disk, bare RL02, and kermit at both
ends.
2.9BSD image on the PC.
Kermit BSD image to RT11 harddisk.
Make RT11 wite the image to the RL02.
Reboot.
Viola. 2.9BSD. Now, I just need the Q-bus MUX that's supported...
All I've got is a few DLV11Js and a DHV11.
I also have something called a DQZ11 (Or maybe DZQ11?) but no cable kit...

It's much easier to have the Q-Bus RL02 controller in a MV2. Run VMS with
CMUIP, on the VAX and FTP the image from the Linux box to the VAX. Then
write the image to the RL02 pack.
Of course like you've I've no cab kit.
However, this doesn't solve the original problem of getting NetBSD onto a
TK50 tape :^)
BTW, what happened when you tried booting the 2.9BSD image? I tried
booting it on my /73 and it came up, but the console went all wierd on me.

[2.9BSD]
It works fine - I play Rogue with it.
Make sure to use 7E1...

I was really planning on hooking it up to my Alpha :-}) , which is why a little
more than ~90MB of tape would be nice....What I was thinking is using the Alpha
(axpci33 running NetBSD) to write a boot tape for the MV3600. Looks like it's
net boot time....If I could afford one, I'd be looking at a DLT2000 or 4000.
But then again, they won't write tapes that the tk70 in the MV3600 can read...

Actually it might not matter if it's only 90Mb. Unless I'm mistaken
doesn't NetBSD only support TK50's on the VAX? I've no idea as to what it
supports under Alpha's. You might want to get ahold of the people doing
the Alpha port, they've probably got a better idea on this one.

Good luck on the net boot. I gave that a try, and gave up once I got VMS.
Of course I think part of my problem was corrupt tar files.
