I feel such nostalgia for Sun hardware. I've had several sparcstations over the years: a SparcStation IPC, SparcStation 5, and an Ultra 10. I still have the Ultra 10, and put OpenBSD on it the other month, after replacing the NVRAM chip.

...but yeah, the slow factor means it doesn't get bench time, the 3/160 almost always gets picked over the 3/50 for hacking. I'd still like to do a dataless install for the 3/50, I recently refurbished a Sun SCSI shoebox with an 80 MB MFM drive on an Adaptec ACB-4000 and that'd probably be the "best" use for it.
And, the future marches on, such as the DECstation 3000 emulator that runs on an RP2040. [0] Seeing a cheap microcontroller doing something like that makes me laugh out loud.
