getting yer old school on with tru64 via es40 emulation

Emulators are fun! Especially when I get to go back to my early days of computing. Back in the day I used to run a 400cpu alpha cluster over at the Sanger. It was all Tru64, all the time. We started out with 4.0f and ended when alpha ended at 5.1b - fun times indeed. Here's a little picture of the tru64 DS10 pie box cluster as it was being built at that time in a machine room in the EBI.

Terrifying times if I were to be totally honest - tru64 is a wicked mistress. Anyone who has ever seen "AdvFS Domain Panic" will understand the true meaning of the word "Panic!".

Anyway, life moves on, we get older (sometimes even wiser), the alpha died out, as did tru64, but there are those epic folks out there that keep the dream alive. I'd been fiddling with ES40/45 emulators for a while over at and they kinda sorta work.

I was looking for full boat nostalgia to get a 5.1 install from scratch via an old ISO and found it over at Seems to be one of the best es40 emulators out there for short or no money. There is the Stromasys stuff that is also pretty cool and also the FreeAXP stuff, but I wanted me an ES40 for no $ ;-)!

Took a while to get all the moving parts together for example we needed a version of putty for linux with gtk2:

mkdir ~/putty
cd ~/putty
svn co svn://
./ # you need to run this to generate the Makefile.gtk used below
cd putty/unix
sudo make -f Makefile.gtk

you need to have the no echo thing set as you can see below this is the alpha emulator doing it's ev6 21264 thing via console, with networking and everything, remember to boot it via sudo, or the pcap networking driver will fail bringing up the LAT and segfault the emulator!

Pretty cool eh? You can even go gang busters and fire up the old ghetto xdmcp from your linux box, to hell with security - these were the days of telnet and plain text! Mind you remembering securettys also caused me heartburn - these were different days of "securing" things, check out the root login via telnet ;-):

well once you remember all that, you can then get back to your XDMCP fun:

Ahhh it takes me back... CDE in full boat 8bit technicolor!

Oh happy days!
