In KSR-35 mode, lower case input and output characters are converted -automatically to upper case, and parity is ignored. In KSR-37 mode, lower -case characters are left alone, and even parity is generated on input. -KSR-37 is the default. - -Once COM is attached and the simulator is running, the 7750 listens -for connections on the specified port. It assumes that any incoming -connection is a Telnet connections. The connections remain open until -disconnected either by the Telnet client, a SET COM DISCONNECT command, -or a DETACH COM command. - -The 7750 implements the following special SHOW commands - - SHOW COM CONNECTIONS displays current connections to the 7750 - SHOW COM STATISTICS displays statistics for active connections - -The 7750 implements the following special SET commands: - - SET COM DISCONNECT=n disconnect line n - SET COMLn LOG=filename log output of line n to filename - SET COMLn NOLOG disable logging and close log file - SET COMLn KSR35 set line n to KSR-35 - SET COMLn KSR37 set line n to KSR-37 - SET COMLn 2741 set line n to 2741 - SET COM CHAN=n set channel for com controller. - -The controller (COM) implements these registers: - - name size comments - - ENABLE 1 enable flag - STATE 6 controller state - MSGNUM 12 input message sequence number - - -2.6 Symbolic Display and Input - -The IBM 7070 simulator implements symbolic display and input.

In addition, units can be -set to enable or disable formatting: - - SET DKn FORMAT enable formatting - SET DKn NOFORMAT disable formatting - SET DKn HA2 enable writing of home address 2 - SET DKn NOHA2 disable writing of home address 2 - SET DKn MODULE=n sets modules for unit, modules - can only be even. 0 to 8. - SET DKn CHAN=n sets channel for unit (A-H). - SET DKn SELECT=n sets select on channel (0 or 1). - SET DKn CTSS sets disk to use CTSS bootstrap. - SET DKn IBSYS sets disk to use IBSYS bootstrap. - -Formatting is disabled by default. - -All Disk units support bootsrapping with boot command. Bootstrap code -is build based on whether CPU is in CTSS mode or not. - - BOOT DKn - -Error handling is as follows: - - error processed as - - not attached report error and stop - - OS I/O error report error and stop - -2.4.2 Hypertape 7340 Tape drive (HTA/B) - -These come in groups of 10 units each. The controller defines which channel -the devices will be on. - - SET HTx CHAN=n Set magtape to channel n. x = A|B. - SET HTx SELECT=n Sets the selection mode for the channel. - -Each individual tape drive support several options: HTA used as an example. - - SET MTAn LOCKED Sets the mag tape to be read only. - SET MTAn WRITEENABLE Sets the mag tape to be writeable. - -NOTE: Hypertape drives may not be working correctly since there is -very little documentation available on them. - -Hypertape drives can be booted with: - - BOOT HTxn - - -2.4.3 7750 Communications Controller (COM and COML) - -The 7750 is modelled as a terminal multiplexor with 33 lines. It consists -of two device: COM is the multiplexor controller, and COML is the indivdual -lines. For the first 32 lines, the 7750 performs input and output through -Telnet sessions connected via a user-specified listening port; the 33rd line -is permanently attached to the simulator console window. The ATTACH command -specifies the port to be used for Telnet sessions: - - ATTACH COM set up listening port - -where port is a decimal number between 1 and 65535 that is not being used -for other TCP/IP activities. - -Each line (each unit of COML) can be set to one of twp modes: KSR-35 and -KSR-37. In KSR-35 mode, lower case input and output characters are converted -automatically to upper case, and parity is ignored. In KSR-37 mode, lower -case characters are left alone, and even parity is generated on input. -KSR-37 is the default. - -Once COM is attached and the simulator is running, the 7750 listens -for connections on the specified port. It assumes that any incoming -connection is a Telnet connections. The connections remain open until -disconnected either by the Telnet client, a SET COM DISCONNECT command, -or a DETACH COM command. - -The 7750 implements the following special SHOW commands - - SHOW COM CONNECTIONS displays current connections to the 7750 - SHOW COM STATISTICS displays statistics for active connections - -The 7750 implements the following special SET commands: - - SET COM DISCONNECT=n disconnect line n - SET COMLn LOG=filename log output of line n to filename - SET COMLn NOLOG disable logging and close log file - SET COMLn KSR35 set line n to KSR-35 - SET COMLn KSR37 set line n to KSR-37 - SET COMLn 2741 set line n to 2741 - SET COM CHAN=n set channel for com controller. - -The controller (COM) implements these registers: - - name size comments - - ENABLE 1 enable flag - STATE 6 controller state - MSGNUM 12 input message sequence number - -2.5 7289 High-Speed Drum (HD) - -The 7289 (also known as the 7320A) high-speed drum was a late -addition to CTSS. Very little is known about the device, other -than what is used in the CTSS sources. - -The drum can be changed to different channels with the - SET HD0 CHAN=n where n is A-H. The channel must be configured - as a 7289 type channel. Otherwise the drum will - not work. - - SET HD0 UNITS=n Sets the number of 256K drums on the unit. - - -Error handling is as follows: - - error processed as - - not attached report error and stop - -Drum data files are buffered in memory; therefore, end of file and OS -I/O errors cannot occur. - - -2.6 Symbolic Display and Input - -The IBM 7090 simulator implements symbolic display and input. Display is -controlled by command line switches: - - -c display as BCD character - -m display instruction mnemonics - -l display as lisp pointer. - -Input parsing is controlled by the first character typed in or by command -line switches: - - ' or -c BCD character - " or -s BCD string - alphabetic instruction mnemonic - numeric octal number - -Instruction input uses standard 7090 assembler syntax. There are two -basic instruction classes: memory reference and index reference. - -Memory reference instructions have the format - - memref{*} address{,tag} - -Index reference instructions have the format - - idxref{*} address,{tag},decrement - -Specific instructions may disallow indirect addressing or limit the -size of the tag, address, or decrement fields. - -Channel (I/O) instructions have the same basic two formats. - -2.7 Sim Load - -The load command looks at the extension of the file to determine how to -load the file. - - .crd Loads a card image file into memory. - standard 709 format + 1 card loader. - .oct Loads an octal deck: - address octal octal... - .sym Loads a 709 symbolic deck. - address instruction. - address BCD string - address OCT octal, octal,....
