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 andStokes                                                          [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).   ... Enc.
