DEC 4000/600

This machine was part of RedIRIS , the Spanish Academic and Research Network and was used in the late 198x, and first 199x.



The box in the left is the Main CPU, at the RIGHT there is hard disk cabinet.

The machine has 64Mb, of memory and was used mainly to provide Internet/OSI related services to the Spanish Research Community.

The machine was used, for example, to keep the X500 directory (LDAP is based in this protocol), and also to provide email (not only SMPT/TCP services, also X.400 ).

Also it's very likely that the first DNS server for the ".es" Top level domain were running
in this machine.


Opening the door we can see that there are three hard disks (one seems to be broken),
ethernet (RJ-45/BNC) connection, console connection (with the typical DEC connector) and some serial card for consoles and serial connexions to other hosts.

DEC 3000/400

This old 64 bit system (according to Wikipedia , this models were build from 1992 to 1995), has been donated by a Spanish University.

This machines were the FIRST with a 64 bit processor (Alpha), from DIGITAL, later buy by compaq , now part of HP, nice world, Digital is one of the historic companies. and Unix was first develoved in a "PDP" series machine.



the system is currenly runninng an old operating system named OSF/1:,

# uname -a
OSF1 theory.cie.uma.es V4.0 878 alpha

but in the ALPHA chip, you could also run OpenVMS (from Digital), most of the free Unix (*BSD, Linux) and also Windows NT for Alpha !!!

This machine has the following hardware configuration:

Interesting is that the machine can be opened very quickly: here is an image of the interior , see the FAN row , they don't produce any noise when running.


unscrewing two screws, the rest of the hardware is opened:



showing the memory banks and CPU and the three fan in a row.



As usual with the Digital system, the console uses a "non standard" connector, named "MMJ", and need also a "MMJ to RJ45" cable named BN24J-07 , with and aditional adaptor from RJ45 to DB9 to be used for console, here you can see the rear part of the machine, with the ethernet connector (RJ45 and AUI), the ISDN and RJ11 (modem) connector and then the MMJ , Serial , Parallel and SCSI connector.



To be able to change the root password the system must boot on single user mode, remount the root partition with read write permissions and then change the /etc/password file , deleting the root password "root::0:1:root users:/:/bin/sh:

• from the boot prompt boot: >>> boot -fl s
• from the # console mount with rw persmissions: mount -u /
• Set the console to VT102 : TERM=vt102
• export TERM
• launch vi : vi /etc/passwd
• Contiene with the booting: exit

This is a new addition to the Museum.
