You mentioned that you had a 3/110 CPU board, which got me thinking: I'm
looking for a 3/110 *chassis*, do you have one you would be willing to
let go of?

Sun2 disk install
I made an interesting rescue last week. a hackerspace moving to a new
was getting rid of some old gear, including Sun-gear. 16 years ago (when
was not yet a hackerspace) I had already rescued a Sun 2/50 from the same
place, that I got to work using a NetBSD-based boot server. (And a Sun
that I parted with, still regretting that.. it is somewhere in the UK
This time, they sent me some pictures of some Sun 3/xx pizza boxes and a
of VME boards. Included on the pictures was a Sun 3/75, which I have been
looking for for almost 2 decades so I was very eager to pick up the
Sadly enough, the Sun 3/75 was just an empty box. I can put in a random
board, but I would really like to put in a Carerra (b3004b) CPU board,
found in the 3/75 (and 3/140, 3/150, 3/160 and 3/180). Itbs a long
but does anybody have one to spare? It would need to be sent to the
Netherlands. Trading for other VME boards is also possible (e.g. 3/110
Not only was the 3/75 empty, a lot of the VME boards were missing parts.

see. There were a bunch of TTL and ECL monitors, that were also
But, to make up for that, there was a Sun 2/120 in there as well that
to go! Given the state of the other stuff, I was fearing the worst for

501-1006 Sun-2 SCSI/Serial
501-1013 1M RAM

501-1048 1M RAM
501-1048 1M RAM
501-1082 Xylogics 451
501-1051 2/120 CPU ROM Rev R
SC4000 SCSI bridge
I can still feel my muscles after getting this thing down from three
After cleaning and confirming that the power worked and the CPU worked, I
started adding boards and they all seem to work as well. Typed in

is a also a SC4000 SCSI board in the case, not connected.
Slot #9 is empty, but therebs something in the back of my mind telling
this slot is special in some kind of way. Can I just use it for any board
just uses the P2 connector?
I would like to put a disk in the 2/120 with an OS. I took the NetBSD
I used as a boot server in 2002 for my 2/50, which still booted. I put
address in /etc/ethers and that was all that was needed to get the 2/120
netboot SunOS 4.0.3, hurray! My plan is to use this running system to
drive, copy all the files over, install boot blocks and that should get
working system. This is probably easier than making boot tapes and fixing
capstan rubber of the QIC drive.
I connected an old SCSI disk directly to the 501-1006 board. The
the bottom is the SCSI so I read. But the kernel does not see a disk
booting, nor does the bformatb command see a disk. I used proper
termination (I thinkb& controller - cable - disk - cable - terminator).
So my questions are:
- do I need a special drive for it to be recognised under SunOS 4.0.3 or
just use any old SCSI disk?
- do I connect the drive directly to the SCSI controller, or do I connect
SC4000 to the controller and the disk and tape drive to the SC4000?
