[bulpper]

Hi!

I'm looking for working PSU for my Sun Ultra 1, model SUN 300-1308. ...or some some tips, or help, for replacing PSU with PC PSU.

Thanks,

Something like that could be an option, but I guess that SUN power might be little bit different...

Eg. type label says 2.5-3.6V @ 12-8.3A.. ? And there is smaller ribbon cable that I have no idea what it is for...

And; I have original PSU but it's completely dead... The backup plan is to fix it, but the again I don't know how
the original PSU should deliver the power

But thats very interesting gadget though =)

I googled Ultra's service manual. Looks like it uses +12v, -12v, +5v, +3.3v and +3.0v, so would need to generate that last one separately.

Anyway, there are people on that project's Discord channel installing this on Sparcstations. I haven't used the PSU myself, just the USB4VC project (to connect USB devices to PS2, gameport etc) from same creator.
