[rescue] Need help in booting Sun 2/50

Your 68030 tapes will not work on the 3/60, which is 68020-based. The 030
tapes are meant for the sun3x machines, the 3/80 and 3/4xx. And the Sun-2's
are yet another architecture, being 68010-based.

The appropriate tape images for all of these are available online, but then
the question is how to get the files onto a tape in the first place. You may
be better off going a different route: installing SunOS on an emulated Sun-3
(because I believe you can use the raw files of a tape image directly with the
emulator rather than having to create a physical tape). Then you can netboot a
physical machine from the emulated machine, and from there you can make
physical tapes, if you still want to.

Hi Steven,

Thanks for your feedback, I just took out the boards for photos and there
is a SCSI board attached which is not from Sun anyway, I think I will do
two ways, one is to resolder the connector and another is like you said
install 4.0.3 in the Sun 3/60 box, BUT, can you give idea on how to install
it? it seems there is no Sun documentation on SunOS 3.X or 4.X online. I
also don't have keyboard and mouse for the Sun 3 and it seems I can only
try to make an adapter to connect the Sun 2 keyboard to CPU..

I have 5 x SunOS 3.5 tape and 2x 4.0.3 domestic 68030 boot format 1/4"
