Yeah, they are old tantalum caps that look like diodes, next to the DRAM. Not electrolytic.
But check the 12v & 5v rails for a short first.. you never know…
My SB II has the dreaded beeeeeeeeeeeeeeeeeeep of death, gah! But I think SB I is ok. They’re in storage right now after a house move, wrapped in plastic and duct tape with all my other machines. Meanwhile, some guys on another forum are getting itchy for some uIDE boards and I’ve not even established an electronics workshop yet. Too busy decorating and DIYing..
Ok. So you will achieve a boot from at least one of those Maslin images (cannot recall which) but the screen will be reversed. I have a proper SBII boot image somewhere. Want a copy?
