   1     Welcome to the IBM System/3 Model 10 SIMH simulator.
   2     ---------------------------------------------------

   4         To compile under linux:
   5
   6         cc s3*.c scp*.c sim_rev.c -o s3
   7
   8         This code can be compiled and run as a console application using
   9         Microsoft Visual C++.

  13         To IPL the provided SCP distribution disk:
  14
  15         ./s3
  16         sim> at r1 m10scp.dsk
  17         sim> at f1 f1f1f1.dsk
  18         sim> at lpt print.txt
  19         sim> d sr 5471
  20         sim> boot r1

  25          // LOAD $MAINT,R1
  26          // RUN
  27          // COPY FROM-R1,LIBRARY-ALL,NAME-DIR,TO-PRINT

  35         The text file "system3.txt" gives details on the simulators
  36         implementation of System/3 hardware.
  37
  38         A write up on the use of the SCP and the OCL job control language is
  39         in the text file "userguide.txt".  This includes examples of using the
  40         utility programs, and a tutorial guiding you thru a sysgen.
  41
  42         A nearly complete listing of all possible SCP halts is in the
  43         document "haltguide.txt".

  45         IMPORTANT NOTES:
  46
  47         1) How to correct typing errors when using the System/3 console:
  48         If you make an error, press ESC, which will cancel the current
  49         line being typed and print a quote in position 1.  Then you
  50         can use CTRL/R to retype characters up until the error, then
  51         type correctly.  Or simply retype the line. BACKSPACE DOES NOT
  52         WORK with the SCP.
  53
  54         2) While the simulator allows disk images to be independently
  55         attached to any disk unit, on the real hardware R1 and F1 were on
  56         a single spindle, and R2 and F2 likewise.  It is not possible using
  57         SCP to attach R1 without attaching a disk image to F1 also, because
  58         SCP will always look at F1 even when IPLed off R1.
  59
  60         The OS distributed with the simulator is version 16 of the Model
  61         10 SCP.  This is sysgenned with support only for R1 and F1.  If you
  62         do a sysgen to support R2 amd F2 also, you must have images attached
  63         to all 4 disks when you IPL, because SCP looks at all drives when
  64         it starts up, and you will get an "Unattached Unit" error if you
  65         fail to have one attached.
  66
  67         3) The 1442 card reader had in reality one card input hopper
  68         and two stackers.  This means the same path is used for reading and
  69         punching cards.  When punching cards, SCP does a read operation
  70         and inspects the card read for blanks, and if it is not blank,
  71         issues a YH halt.  SCP will not punch data onto non-blank cards.
  72         This feature causes problems in the simulator, and as a result
  73         if you punch cards from SCP, YOU MUST not have any file attached
  74         to the CDR device.  Leaving this device unattached presents an
  75         infinite supply of blank cards to SCP for punching.
