One issue I ran into was no pre-built packages for newer releases, so when I updated to 6.5 I had to downgrade to 6.3 to get any packages. Sans that, it's also unfortunate that Common Lisp implementations don't tend to support a MIPS that isn't under GNU/Linux; the GNAT compiler for Ada also isn't available. I can get GNU APL though, so that's nice.
Since some are wondering, I bought mine about eight years back for a few hundred dollars and even back then the website that supplied mine soon ran out of stock.
This article has reminded me that I'd intended to make pictures and descriptions of my Lemote Yeeloong available on my website months back, which is a great option for my 2019-09-09 article, so I'll do so.
Owning this machine has been a nice way to not use x86(_64) for everything and it's made me intent on my software working properly on less common machines and operating systems. My choices of language have likely already betrayed that, but I eventually intend to write implementations of my own and I'll ensure my Lemote Yeeloong is well supported. I also must remember that OpenBSD may not support it forever, although I could perhaps take over if it's ever necessary.
I could write more concerning this, but this seems sufficient.
