Michael from the Adelaide Retro Computing Group had a Sun CDROM drive arrive for recycling. He kindly sent it my way. I think it’s probably one generation newer than the IPX but it will do.
Like the DEC CDROM, it was non-functional due to leaking capacitors. Once they were replaced, it made a great addion to the lunch box stack.
Michael also came up with a very weathered Sun CPD-1790AS monitor. It really needs a lot of work to clean up the interior metalwork. It is operational though.
The original optical mouse had always been a pain. While acquiring Sun Keyboards for my Ultra 5 project, i also gained several mice, including a Sun Compact 1 Ball Mouse which work much better than the optical mouse.
