The main desktop is still the SGI O2 (CPU: MIPS R10000 @250 MHz, RAM: 1
GB, HDD: 32 GB, IRIX 6.5.27). The only change was increasing list of
WWW servers which cannot be accessed from this computer because they
switched to HTTPS and use CPU-intensive (or too new) encryption
protocols. The rest works as always (Vim, LaTeX, XFig, Gimp, OpenGL 1.1
stuff).
I used the Lenovo X61s as a secondary desktop (well, to browse the WWW
and to connect USB devices) but I have had to replace it with the
ODROID ARM-based desktop. It is 32bit machine with 2 GB of RAM which
have introduced some unexpected problems (there is no 32bit Firefox so
I have to use Chromnium) and there are issues not only with graphical
Links browser (it does not work) but also with colors in teh Gimp and
with icons on the LibreOffice (they re invisible). But it is a device
for WWW which works enough (so far). It runs the Ubuntu MATE 16.04.
With unusual luck I have got a IBM IntelliStation 285 near for free. I
have expected to used it more but it is not so easy to configure it to
fit my needs. But it has 2 POWER5+ CPU cores which is not bad. It have
3 HDDs (one with the AIX, one with Linux and one unused). I should
manage the 3rd one to be a place for data. The problem of this device
is its 8 GB of RAM. I thought that it is enough but I needed to do some
computations which required more... Anyway it is probably my fastest
computer.
Sometimes I use my SGI IRIS Indigo (33 MHz MIPS CPU, 96 MB of RAM, IRIX
5.3) just to browse Gopherspace or to write something with little
distraction (it can access the outside world only via gopher, ftp and
plain old http). I developed a habit to use the Indigo on Saturdays
instead of the O2.
