[rescue] Small cache of Sun2 boards/systems to test.

[Steve Piette]

I have a collection, cache, big pile of old Sun hardware including
several 2/120 and 2/170 systems and spares to weed through.

I've put together a 120 backplane and power supply for testing the
various boards but I'm afraid to try using any of my 1/4" tapes due the
the drive belt issues or powering up any of the machines with 1/2"
drives considering it's been almost two decades since most of it was
last powered up.

Does anyone have the diagnostics for the 68010 machines or a bootable OS
handy I could get a copy of so I can see what works and what needs repair.

Thanks,

Steve

If you have the Multibus SCSI host adapter, it's possible to create a bootable
OS disk using a newer machine running SunOS 4. After copying and booting the
miniroot, the install just untars tape files, then runs makedev, creates an
fstab, and installs a boot block. I can walk you through it if it would be
helpful to you.

It's possible to use a modern disk too, though not necessarily completely
straightforward to get it set up so the Multibus SCSI host adapter is happy
with it. I captured some notes here:

I have several 501-1006 Multibus SCSI host adapters but ATM no running
Sun machines to format a drive on. I guess I should fix one of them up
first.

It's been a long time but I seem to remember I could dd disk images
between SCSI disks but not SMD and ESDI drives due to drive parameters
being on disk. I barely remember installing the OS 3.X and 4.X but I do
remember rebuilding the kernel to reconfigure or add devices.

Speaking of the MB SCSI HA, does anyone have a part number label still
on the center most 16R4 PAL next to U300. I have all the other PALs
labeled but that one.

Thanks, I found your site early on in the search to refresh my long
paged out memories. What you've posted was useful.

Fearing the loss of something important reusing any of my existing
drives I've got a SCSI2SD on order.

I have all this stuff, ping me tomorrow and Ibll upload a bootable disk
image somewhere.

i've only done it between scsi disks and only on sunos4 and solaris2,
but you may be able to pipe dump to restore to move images. dump
works on the raw device but - on later systems at least - restore
works within the fs, so if you can format the target drive you're good
to go.

you could also use tar or cpio piplines, but in my experience
dump/restore was faster than anything except dd, and it was more
flexible.
