Cray collection

we collected a bunch of Crays. The Y-MP EL in front is currently working, the others behind will be restored one day.

Collection of Crays

Crays and Cybers

These two will only be for display, but won't be running again.

When you unpack the tarball of gcc-2.9 and start compiling and it stops with the strange error, that the built stuff is older than the content of the tarball. Welcome on my #Cray, which remains in 1993.
So had to touch a lot of files to get them back to history lane.... #datArena

TeX 3.0 reel edition

If you get software in a reel, you need the right equipment to read it.

Hollerith or IBM?

We found something older than our Siemens Telephonysystem from 1922.

Telefonanlage Siemens 1922

It is a manual card punch from the Deutsche Hollerith Maschinen Gesellschaft M.B.H. Berlin from 1920.

It was later sold by IBM. IBM - Handlocher Modell 011 Baujahr 1920

And the interlink is heavy. The connectors are upside down and off by a few millimeters. Took ages to get it plugged in correctly.

Why does booting a #PDP8 straight eight take 20 minutes? The #Teletype isn't any faster reading the paperstrip...

And another #robertredford movie "Three days of the condor" with a #PDP8e a card punch and a printer-terminal. You can visit the #datArena to see systems like this in our minicomputer area.

Perl on a Cray Y-MP EL

Compiling Perl on a Cray is not an easy task, if you only have a few hours every Tuesday. And taking a Cray home, even the little Y-MP EL, is not an option. Neither is letting it run unattended.

The frustrating part is the wait. Unicos does not even have a 'top' command, so ps -efa is your best friend

Testing the read/write head of a RK05

Testing the read/write head of a RK05

We were testing the read/write head of the RK05 with the alignment disk. So the drive is fine, but the PDP-11 is still not booting. Has some one wipe the disk of content?

Altes Eisen

Eine Tour durch das historische Rechenzentrum der datArena

Wir haben mal eine kurze Präsentation des historischen Rechenzentrums erstellt. Und zeigen diese auch beim https://www.vcfe.org VCFe während der optionalen Führungen.
