Fujitsu for general purpose servers, and Atmel (maybe others too?) for rad-hardened Sparc.

> Atmel

Microchip these days, Atmel got acquired few years back..

The packaging looks cool of those https://www.microchip.com/wwwproducts/en/AT697F

That's how it's packaged prior to trimming and lead forming, which looks like this:

That is an interesting look. There's an 8 bit ATMEGA like that too: https://www.microchip.com/wwwproducts/en/ATmegaS128

I wonder what that form factor with the chip suspended like that actually does for it.

Given that Fujitsu has jumped ship to ARM for their supercomputers I wonder if they'll be doing so with their other hardware as well?

Gaisler and the ESA are launching SPARC into space.

They are using risc-v for their 64-bit cores now.

The context was not "Who isn't using RISC-V?" It was whether anyone is using SPARC. The reality: they're not mutually exclusive. They offer both, contrary to the implied subtext of your comment that there has been a transition from SPARC to RISC-V.

No one worth mentioning AFAIK.
