本文探討瞭如何修復一臺經典的 Sun SPARCstation IPX 工作站。作者首先回顧了 90 年代初期 UNIX 工作站在性能和功能上如何超越當時的個人電腦,並介紹了 SPARCstation IPX 的硬體規格及其在當時的高昂售價與特定應用。接著,文章詳述了該機器的主要問題——電源供應器故障,其肇因於老舊電解電容器的失效與洩漏,這在 IPX 和 IPC 型號中屬常見現象。為了讓機器恢復運作,作者逐步說明瞭如何更換電源供應器內的所有電解電容器,並列出所使用的具體零件型號與規格。儘管 NVRAM 的修復細節在本文中尚未提及,但此篇為 S

Someone's old Sun SPARCstation IPX fan page I ran across today, randomly.

I love old pages like this.

Ok, here's the blog post!

If you've wanted to party like it's 1994 and experience life on planet #Unix _before_ Solaris, why not try a bit of #RetroComputing and try #SunOS 4 on an emulated #SPARCstation 5? https://apintandaparma.club/cos/falling-down-a-rabbit-hole-of-nostalgia-episode-1-sunos-4

Trying to remember a unix gag from the early 90s. You could send a command to someone else's terminal and a little guy would appear on screen and slowly push the whole thing off your monitor. If you knew what was up, you could kill the process, but if not, you'd be locked out. I'd swear this was called "Ferkle", but I can't find anything mention of this anywhere. This was on a Sun SPARCstation, I believe.

Anyone?

The #sparcstation lives! It's been nearly a decade. Not sure why I can't get a console in my regular user account, but that's the least of my worries. Is there a way to use Sun OpenLook without a mouse? #sun4m #retrocomputing #retrounix
Flashback: Sun SPARCstation 20 running OpenBSD as mail server

En the early 2000s, when I was in education, I had to complete a project by my own. As I somehow got a Sun SPARCstation 20, with a few GB of disk and - as I remember - 256 MB of RAM. The CPU was a SPARC 32bit. I decided
