System Status
19 October 2018: VAX-11/780-5 to be replaced by VAX 7000-640

We will be moving all OpenVMS accounts from the 11/785 to a 7640 beginning on
Monday, 22 October 2018.  All software licenses will be transferred, so there
should be no user visible changes in operation other than the higher speed of
the new processor.  This should take 2 days, and VMS will be available again by
Wednesday.  The 11/785 will be retargeted for another operating system, to be
announced later.


16 October 2018: CDC 6500 UP!

The compressor in the chiller was successfully replaced on Monday, 15 October
2018, and the system is up and running.  We apologize for the extended downtime
and thank the users for their patience.


28 September 2018: IBM 4361 (VM/SP) down indefinitely

The 4361 was down for more than a month with a hardware failure in a channel
interface.  We eventually replaced the external peripheral emulator's channel
emulation card, and were able to bring the system back to life for about 10
days, but it suffered a massive internal power related failure last night and
cannot be brought back up.  We have no estimate on when the system will return
to service at this time.  We apologize for the inconvenience.



10 July 2018: DECSYSTEM-2065 down (Tops-10)

The diagnosis has come in regarding the 2065:  Repairs are necessary on the
entire CPU board set.  We expect the system to be down for another two weeks.
We apologize for the inconvenience.




28 February 2017: CP-V (Sigma 9) accounts

Updating the message from last month:  We have learned that the system was
built on a so-called private disk pack, which is limited to a maximum of
96 distinct accounts.  We are working on building a public pack system,
which does not have this limitation.  We appreciate your continued patience.

14 August 2018: IBM 4361 (VM/SP) down

UPDATE:  The system crashed on Friday, 10 August, with a channel failure of
some kind, reporting that it could not find its disk drives.  FSI checked the
logs on the FLEXCUB disk emulator, and noted that the system was unable to
connect to them.  We have run the IBM diagnostics, and are in the process of
replacing 2 boards in the channel.  We apologize for the ongoing inconvenience.


10 August 2018: IBM 4361 (VM/SP) down

The 4361 crashed with a channel problem of some kind today.  The support
people from FSI are looking at the logs on the FLEX-CUB device emulator
to determine what has happened and how we move forward.  We apologize
for the inconvenience.


10 July 2018: CDC 6500 down

The compressor in the chiller for the 6500's coolant fluid has broken down and
must be replaced.  At this time there is no estimate for a repair and return to
service.  We apologize for the inconvenience.


5 July 2018: CDC 6500 down

The chiller for the 6500's coolant fluid has broken down.  At this time there
is no estimate for a repair and return to service.  We apologize for the
inconvenience.



8 June 2018: DECSYSTEM-2065 (Tops-10)

Due to unscheduled electrical work on its UPS, the 2065 is down with a serious
hardware failure.  We have no estimate for how long the repair will take; we
apologize for the inconvenience.



28 March 2018: VAX-11/780-5 (VMS 7.3) upgrade

We have replaced the disks on the 785 in order to upgrade the disk service to
an Emulex SCSI controller connected to an SD card disk emulation.  This will
provide more stable file service in the future.

  Due to continuing network-based attacks on the TOPS-20 systems, we have disabled
  the use of TELNET as the way to log on to them, and will require the use of a
  2-stage connection via SSH to our firewall using a new well-known user address.
  After 12:00 NOON on Monday, 4 December 2017, please connect to the public TOPS-20
  system with the following credential:

			toad-2@TTY.livingcomputers.org

  We apologize for any inconvenience this may cause.

7 June 2017: DECSYSTEM-10 CONNECTION CHANGE!  PLEASE READ!

For technical reasons, we have had to change the way in which users of the
DEC-10 (2065 running Tops-10) connect to the system.  It can no longer be
reached by TELNETing to

			DEC-10.LivingComputerMuseum.org

Instead, please use SSH to connect to

			dec-10@tty.LivingComputers.org

which will take you to the usual Tops-10 login prompt.

24 March 2017: BSD4.3 (VAX-11/730)

The system is down for the weekend.  Expect normal operations to resume on
Monday.  We apologize for the inconvenience.

28 February 2017: Tops-10 (DEC 2065)

Yesterday evening the main power supply experienced an age-related issue.
Getting at the non-functioning device and orderng a replacement will take
several days.  Watch here for further news.
********************************************************************************

13 February 2017: VMS (VAX 785) logins

In order to prevent VMS lockouts, Telnet and SSH logins have been turned off.
To log in to the VAX, ssh to vax780@TTY.LivingComputerMuseum.org to connect
automatically via an internal network at the museum.

27 January 2017: CP-V (Sigma) logins failing

Several people who just received new accounts on the Sigma 9 have reported that
they are unable to log in with their new credentials.  We are investiagting the
issue and expect to have an answer shortly.  Thank you for your patience.

4 May 2016:  CP-V (Sigma) down

Our apologies for the late notice.

Memory has been flaky for some time, and we have been running with half of the
memory turned off.  Recently, some new jobs failed because of insufficient
memory, so we are working to fix it.  The system will be down sporadically for
extended (overnight) periods for the next two weeks.
********************************************************************************

25 January 2016:  CP-V (Sigma 9) running again

The apparent memory fault was more complex than we expected.  The actual source
of the failure was a blown component on a circuit card used (in the original
configuration) to connect a Sigma 6 to the same memory as the Sigma 9.  This
component was holding a signal down so that nothing else could access the
memory.

Thank you all for your patience while we diagnosed this problem.
********************************************************************************

15 December 2015:  CP-V (Sigma 9) down

The Sigma 9 hung today with what appears to be a memory fault, although there
is also a possibility that it is a CPU failure.  We are working to converge on
the cause and to get the system running again as quickly as possible.  We ask
for your patience.
********************************************************************************

1 October 2015:  Tops-10 (2065) system up

On 20 August 2015, the serial line card in the front end processor of the 2065
died.  We eventually found a replacement card, but in the mean time the memory
interface in the CPU developed a problem.  We have now replaced the failing
card in the CPU, and the system is back up for timesharing.
********************************************************************************

30 July 2015:  Accounts on Sigma 9 and PDP-11/70 now open
  
23 July 2015:  Sigma 9 CP-V, PDP-11/70 Unix v7

Requests for accounts are currently being accepted.  There may be some delay
in setting them up.  We ask for your patience as these new systems move to
operational status.

25 June 2015:  2065 Tops-10 7.04

All user accounts have been moved onto a larger disk (RP07 instead of RP06),
directories on the old MDE drives MONE:, MTWO:, MTRE:, and MFOR: have been
moved to DSKM: (RP07), and directories on the old RP06 MDE disks DSKK:, DSKL:,
DSKM:, and DSKO: have been moved onto DSKO: (RP07).
