Got one of my Sun3's open - no life yet - but they don't look too bad; look at that BBC Engineering sticker; and they're neighbouring serial numbers on the machines - these are siblings! Few fun board bodges.

A Sun3 mainboard - at the back there are 24 SIMM slots, 20 of them are filled with 1MB simms It's big - it drawfs the 68020 in the middle. To the bottom right is the graphics card.
A PAL with one of it's pins obviously cut
The back showing the serial numbers
The other side of hte back showing the video sockets an unusual huge (68pin?) D scsi, and a 'BBC Engineering chiswick - Audio section' sticker.

I've just extracted my #suntember projects from the bottom of the pile. A pair of Sun 3/60's. They weigh 12kg each - I guess the case was designed to withstand the weight of the monitors.
#retrocomputing

A stack of old Unix workstations on a trolly. From top to bottom; an SGI Indy, a Sun Ultra 1, an HP 9000/735 and two Sun 3/60's. In front is the corner of a Sun3 optical mouse mat and keyboard. They're sitting on a black dolly.
