Network Working Group A. Stokes Request for Comments: 588 UKICS NIC: 20217 October 1973

                       LONDON NODE IS NOW UP
 The London node of the ARPANET has been on the Net (Address 42) since
 early September.  It consists of a TIP (Address 170) and, at present,
 a local HOST (0), a PDP-9, which front-ends the Rutherford High
 Energy Laboratory 360/195 located 60 miles from London and connect to
 it by a 2.4 Kbps line.  The specific details of the 360 will soon
 appear in the Resource Notebook, but, in brief, it has 2 megabytes of
 fast store (750ns), a fixed head disk and a large number of other
 peripherals.  It operates under OS/MVT release 21.7 and HASP II
 version 3.1, with a locally written message switching system MAST and
 an interactive editor ELECTRIC.  In addition to the local hardware,
 it supports about 20 remote workstations, which are, in many cases
 GEC 2050s simulating IBM 1130s.  Eventually, other Hosts will be
 attached to the Very Distant Host Interface (Address 234).
 The PDP-9 at the Institute of Computer Science also simulates a 1130
 with 2 card readers, 2 card punches, two line printers, three MAST
 consoles, and a system console.  It has a 16K (18 bit) words store, a
 256K word drum and a number of devices usually attached by modem
 interfaces.  The 1130 simulator software has been interfaced to an
 ARPA system, which, at present, has IMP-HOST, HOST-HOST, ICP, and
 TELNET protocols.  The TELNET link is initially to the PDP-9 from
 whence the user may login to the 360 provided one of the two MAST
 ports is available (the third being for local use).  The access is to
 ELECTRIC, and the user may enter and edit files, submit them to the
 batch stream, and inspect the output interactively from a terminal.
 The facilities will be extended soon to allow the printing of jobs at
 TIPS and later the RJE and FTP protocols will be implemented.
 The 360 is available for limited experimental use, and a free login
 facility has been provided (GUEST).  This account has a very limited
 allowance (currently, 1min CPU time/week), and is designed only for
 demonstration purposes.
 All jobs under this account must be Class X, which has a maximum run
 time of 10secs.  Proper accounts, for which there will be no charge,
 can be arranged for appropriate users by contacting KIRSTEIN@ISI.  It
 is not planned, at present, to make the 360/195 a normal service
 HOST, like for example, the CCN machine.  However, the machine will
 be made available for cooperative projects involving a US group and

Stokes [Page 1] RFC 588 London Node is Now Up October 1973

 an interested party in the UK.  Of particular interest to us are
 applications in Network measurements, high energy physics, and
 accelerator design, though other projects would be considered.
 Primitive HELP facilities exist on both the PDP-9 and the 360, and
 they are accessed by %H and TYPE JB=HELP, respectively.  Up to date
 details will be given in the message obtained on connecting to the
 PDP-9 and in the PDP-9 Help file.
 ... A typical scenario is attached.
 The intention is to keep the PDP-9/360 available as a HOST between
 19.00 and 09.00 local time, as well as a number of periods during the
 day (the local time is 8 or 9 hours ahead of California, and 5 hours
 ahead of the East Coast).  There will be no operator available on the
 PDP-9, although during the day and at least the early part of the
 evening, there will be users in the computer room who will give
 assistance where necessary.  The "operator's console" is a Teletype,
 so any messages sent during the night will be read in the morning,
 and we will try to send replies to all queries (if you tell us where
 to reply to Network mail for our site may be send to KRISTEIN@ISI, or
 to myself (IDENT=AVS) at the NIC.  Connection problems should be
 referred to Peter Higginson (NIC ident = PLH).
