2. PDP-10 Features
|
||||
|
||||
The PDP-10 simulator is configured as follows:
|
||||
|
||||
device simulates
|
||||
name(s)
|
||||
|
||||
CPU KS10 CPU with 1MW of memory
|
||||
PAG paging unit (translation maps)
|
||||
UBA Unibus adapters (translation maps)
|
||||
FE console
|
||||
TIM timer
|
||||
PTR,PTP PC11 paper tape reader/punch
|
||||
RY RX211/RX02 floppy disk and two drives
|
||||
DZ DZ11 8-line terminal multiplexor (up to 4)
|
||||
LP20 LP20 line printer
|
||||
RP RH11/RP04/RP05/RP06/RP07/RM03/RM05/RM80 controller with
|
||||
eight drives
|
||||
TU RH11/TM02/TU45 controller with eight drives
|
||||
XU DEUNA/DELUA Ethernet controller
|
||||
|
||||
The PTR, PTP, and RX211 are initially set DISABLED. The DZ11 and LP20 can
|
||||
also be set DISABLED. Some devices support the SET ADDRESS command, which
|
||||
allows the I/O page address of the device to be changed, and the SET VECTOR
|
||||
command, which allows the vector of the device to be changed. All devices
|
||||
support the SHOW ADDRESS and SHOW VECTOR commands, which display the device
|
||||
address and vector, respectively.
|
||||
|
||||
The PDP-10 simulator implements several unique stop condition:
|
||||
|
||||
- illegal instruction (000) in kernel mode
|
||||
- indirect addressing nesting exceeds limit
|
||||
- execute chaining exceeds limit
|
||||
- page fail or other error in interrupt sequence
|
||||
- illegal instruction in interrupt sequence
|
||||
- invalid vector pointer in interrupt sequence
|
||||
- invalid Unibus adapter number
|
||||
- non-existent exec or user page table address
|
||||
|
||||
The PDP-10 loader supports RIM10B format paper tapes, SAV binary files, and
|
||||
EXE binary files. LOAD switches -r, -s, -e specify RIM10, SAV, EXE format,
|
||||
respectively. If no switch is specified, the LOAD command checks the file
|
||||
extension; .RIM, .SAV, .EXE specify RIM10, SAV, EXE format, respectively.
|
||||
If no switch is specified, and no extension matches, the LOAD command checks
|
||||
the file format to try to determine the file type.
|
||||
|
||||
2.1 CPU
|
||||
|
||||
The CPU options allow the user to specify standard microcode, standard
|
||||
microcode with a bug fix for a boostrap problem in TOPS-20 V4.1, or ITS
|
||||
microcode:
|
||||
|
||||
SET CPU STANDARD Standard microcode
|
||||
SET CPU TOPS20V41 Standard microcode with TOPS-20 V4.1 bug fix
|
||||
SET CPU ITS ITS compatible microcode
|
||||
|
||||
The CPU implements a SHOW command to display the I/O space address map:
|
||||
|
||||
SHOW CPU IOSPACE show I/O space address map
|
||||
|
||||
CPU registers include the visible state of the processor as well as the
|
||||
control registers for the interrupt system.

|
||||
REG[0:127] 36 fast memory blocks
|
||||
|
||||
The CPU can maintain a history of the most recently executed instructions.
|
||||
This is controlled by the SET CPU HISTORY and SHOW CPU HISTORY commands:
|
||||
|
||||
SET CPU HISTORY clear history buffer
|
||||
SET CPU HISTORY=0 disable history
|
||||
SET CPU HISTORY=n enable history, length = n
|
||||
SHOW CPU HISTORY print CPU history
|
||||
SHOW CPU HISTORY=n print first n entries of CPU history
|
||||
|
||||
The maximum length for the history is 65536 entries.
|
||||
|
||||
2.2 Pager
|
||||
|
||||
The pager contains the page maps for executive and user mode. The
|
||||
executive page map is the memory space for unit 0, the user page map the
|
||||
memory space for unit 1. A page map entry is 32 bits wide and has the
|
||||
following format:
|
||||
|
||||
bit content
|
||||
--- -------
|
||||
31 page is writeable
|
||||
30 entry is valid
|
||||
29:19 mbz
|
||||
18:9 physical page base address
|
||||
8:0 mbz
|
||||
|
||||
The pager has no registers.
|
||||
|
||||
2.3 Unibus Adapters
|
||||
|
||||
The Unibus adapters link the system I/O devices to the CPU. Unibus
|
||||
adapter 1 (UBA1) is unit 0, and Unibus adapter 3 is unit 1. The
|
||||
adapter's Unibus map is the memory space of the corresponding unit.
|
||||
|
||||
The Unibus adapter has the following registers:
|
||||
|
||||
name size comments
|
||||
|
||||
INTREQ 32 interrupt requests
|
||||
UB1CS 16 Unibus adapter 1 control/status
|
||||
UB3CS 16 Unibus adapter 3 control/status
|
||||
|
||||
2.4 Front End (FE)
|
||||
|
||||
The front end is the system console. The keyboard input is unit 0,
|
||||
the console output is unit 1. It supports one option:
|
||||
|
||||
SET FE STOP halts the PDP-10 operating system
|
||||
|
||||
The front end has the following registers:
|
||||
|
||||
name size comments
|
||||
|
||||
IBUF 8 input buffer
|
||||
ICOUNT 32 count of input characters
|
||||
ITIME 24 keyboard polling interval
|
||||
OBUF 8 output buffer
|
||||
OCOUNT 32 count of output characters
|
||||
OTIME 24 console output response time
|
||||
|
||||
2.5 Timer (TIM)
|
||||
|
||||
The timer (TIM) implements the system timer, the interval timer, and
|
||||
the time of day clock used to get the date and time at system startup.
|
||||
Because most PDP-10 software is not Y2K compliant, the timer implements
|
||||
one option:
|
||||
|
||||
SET TIM NOY2K software not Y2K compliant, limit time
|
||||
of day clock to 1999 (default)
|
||||
SET TIM Y2K software is Y2K compliant
|
||||
|
||||
The timer has the following registers:
|
||||
|
||||
name size comments
|
||||
|
||||
TIMBASE 59 time base (double precision)
|
||||
TTG 36 time to go (remaining time) for interval
|
||||
PERIOD 36 reset value for interval
|
||||
QUANT 36 quantum timer (ITS only)
|
||||
TIME 24 tick delay
|
||||
DIAG 1 use fixed tick delay instead of autocalibration
|
||||
|
||||
Unless the DIAG flag is set, the timer autocalibrates; the tick delay
|
||||
is adjusted up or down so that the time base tracks actual elapsed time.
|
||||
This may cause time-dependent diagnostics to report errors.
|
||||
|
||||
2.6 PC11 Paper Tape Reader (PTR)
|
||||
|
||||
The paper tape reader (PTR) reads data from a disk file. The POS
|
||||
register specifies the number of the next data item to be read. Thus,
|
||||
by changing POS, the user can backspace or advance the reader.
|
||||
|
||||
The paper tape reader requires an unsupported driver under TOPS-10
|
||||
and is not supported under TOPS-20 or ITS.
|
||||
|
||||
The paper tape reader implements these registers:
|
||||
|
||||
name size comments
|
||||
|
||||
BUF 8 last data item processed
|
||||
CSR 16 control/status register
|
||||
INT 1 interrupt pending flag
|
||||
ERR 1 error flag (CSR<15>)
|
||||
BUSY 1 busy flag (CSR<11>)
|
||||
DONE 1 device done flag (CSR<7>)
|
||||
IE 1 interrupt enable flag (CSR<6>)
|
||||
POS 32 position in the input file
|
||||
TIME 24 time from I/O initiation to interrupt
|
||||
STOP_IOE 1 stop on I/O error
|
||||
|
||||
Error handling is as follows:
|
||||
|
||||
error STOP_IOE processed as
|
||||
|
||||
not attached 1 report error and stop
|
||||
0 out of tape
|
||||
|
||||
end of file 1 report error and stop
|
||||
0 out of tape
|
||||
|
||||
OS I/O error x report error and stop
|
||||
|
||||
|
||||
2.7 PC11 Paper Tape Punch (PTP)
|
||||
|
||||
The paper tape punch (PTP) writes data to a disk file. The POS
|
||||
register specifies the number of the next data item to be written.
|
||||
Thus, by by changing POS, the user can backspace or advance the punch.
|
||||
|
||||
The paper tape punch requires an unsupported driver under TOPS-10
|
||||
and is not supported under TOPS-20 or ITS.
|
||||
|
||||
The paper tape punch implements these registers:
|
||||
|
||||
name size comments
|
||||
|
||||
BUF 8 last data item processed
|
||||
CSR 16 control/status register
|
||||
INT 1 interrupt pending flag
|
||||
ERR 1 error flag (CSR<15>)
|
||||
DONE 1 device done flag (CSR<7>)
|
||||
IE 1 interrupt enable flag (CSR<6>)
|
||||
POS 32 position in the input or output file
|
||||
TIME 24 time from I/O initiation to interrupt
|
||||
STOP_IOE 1 stop on I/O error
|
||||
|
||||
Error handling is as follows:
|
||||
|
||||
error STOP_IOE processed as
|
||||
|
||||
not attached 1 report error and stop
|
||||
0 out of tape
|
||||
|
||||
OS I/O error x report error and stop
|
||||
|
||||
2.8 DZ11 Terminal Multiplexor (DZ)
|
||||
|
||||
The DZ11 is an 8-line terminal multiplexor. Up to 4 DZ11's (32 lines)
|
||||
are supported. The number of lines can be changed with the command
|
||||
|
||||
SET DZ LINES=n set line count to n
|
||||
|
||||
The line count must be a multiple of 8, with a maximum of 32.
|
||||
|
||||
The DZ11 supports three character processing modes, 7P, 7B, and 8B:
|
||||
|
||||
mode input characters output characters
|
||||
|
||||
7P high-order bit cleared high-order bit cleared,
|
||||
non-printing characters
|
||||
suppressed
|
||||
7B high-order bit cleared high-order bit cleared
|
||||
8B no changes no changes
|
||||
|
||||
The default is 7B, for compatability with TOPS-20.
|
||||
|
||||
The DZ11 supports logging on a per-line basis. The command
|
||||
|
||||
SET DZ LOG=line=filename
|
||||
|
||||
enables logging for the specified line to the indicated file. The
|
||||
command
|
||||
|
||||
SET DZ NOLOG=line
|
||||
|
||||
disables logging for the specified line and closes any open log file.
|
||||
Finally, the command
|
||||
|
||||
SHOW DZ LOG
|
||||
|
||||
displays logging information for all DZ lines.
|
||||
|
||||
The terminal lines perform input and output through Telnet sessions
|
||||
connected to a user-specified port. The ATTACH command specifies
|
||||
the port to be used:
|
||||
|
||||
ATTACH {-am} DZ <port> set up listening port
|
||||
|
||||
where port is a decimal number between 1 and 65535 that is not being used
|
||||
for other TCP/IP activities. The optional switch -m turns on the DZ11's
|
||||
modem controls; the optional switch -a turns on active disconnects
|
||||
(disconnect session if computer clears Data Terminal Ready). Without
|
||||
modem control, the DZ behaves as though terminals were directly connected;
|
||||
disconnecting the Telnet session does not cause any operating system-
|
||||
visible change in line status.
|
||||
|
||||
Once the DZ is attached and the simulator is running, the DZ will listen
|
||||
for connections on the specified port. It assumes that the incoming
|
||||
connections are Telnet connections. The connection remains open until
|
||||
disconnected by the simulated program, the Telnet client, a SET DZ
|
||||
DISCONNECT command, or a DETACH DZ command.
|
||||
|
||||
The SHOW DZ CONNECTIONS command displays the current connections to the DZ.
|
||||
The SHOW DZ STATISTICS command displays statistics for active connections.
|
||||
The SET DZ DISCONNECT=linenumber command disconnects the specified line.
|
||||
|
||||
The DZ11 implements these registers:
|
||||
|
||||
name size comments
|
||||
|
||||
CSR[0:3] 16 control/status register, boards 0-3
|
||||
RBUF[0:3] 16 receive buffer, boards 0-3
|
||||
LPR[0:3] 16 line parameter register, boards 0-3
|
||||
TCR[0:3] 16 transmission control register, boards 0-3
|
||||
MSR[0:3] 16 modem status register, boards 0-3
|
||||
TDR[0:3] 16 transmit data register, boards 0-3
|
||||
SAENB[0:3] 1 silo alarm enabled, boards 0-3
|
||||
RXINT 4 receive interrupts, boards 3..0
|
||||
TXINT 4 transmit interrupts, boards 3..0
|
||||
MDMTCL 1 modem control enabled
|
||||
AUTODS 1 autodisconnect enabled
|
||||
|
||||
The DZ11 does not support save and restore. All open connections are
|
||||
lost when the simulator shuts down or the DZ is detached.
|
||||
|
||||
2.9 RH11 Adapter, RM02/03/05/80, RP04/05/06/07 drives (RP)
|
||||
|
||||
The RP controller implements the Massbus 18b (RH11) direct interface for
|
||||
large disk drives. It is more abstract than other device simulators, with
|
||||
just enough detail to run operating system drivers. In addition, the RP
|
||||
controller conflates the details of the RM series controllers with the RP
|
||||
series controllers, although there were detailed differences.
|
||||
|
||||
RP options include the ability to set units write enabled or write locked,
|
||||
to set the drive type to one of six disk types, or autosize:
|
||||
|
||||
SET RPn LOCKED set unit n write locked
|
||||
SET RPn WRITEENABLED set unit n write enabled
|
||||
SET RPn RM03 set type to RM03
|
||||
SET RPn RM05 set type to RM05
|
||||
SET RPn RM80 set type to RM80
|
||||
SET RPn RP04 set type to RP04
|
||||
SET RPn RP06 set type to RP06
|
||||
SET RPn RP07 set type to RP07
|
||||
SET RPn AUTOSIZE set type based on file size at attach
|
||||
|
||||
The type options can be used only when a unit is not attached to a file.
|
||||
Note that TOPS-10 V7.03 supported only the RP06 and RM03; V7.04 added
|
||||
support for the RP07. TOPS-20 V4.1 also supported only the RP06 and
|
||||
RM03. Units can be set ENABLED or DISABLED.
|
||||
|
||||
The RP controller implements these registers:
|
||||
|
||||
name size comments
|
||||
|
||||

|
||||
|
||||
2.12 RX211/RX02 Floppy Disk (RY)
|
||||
|
||||
RX211 options include the ability to set units write enabled or write
|
||||
locked, single or double density, or autosized:
|
||||
|
||||
SET RYn LOCKED set unit n write locked
|
||||
SET RYn WRITEENABLED set unit n write enabled
|
||||
SET RYn SINGLE set unit n single density
|
||||
SET RYn DOUBLE set unit n double density (default)
|
||||
SET RYn AUTOSIZE set unit n autosized
|
||||
|
||||
The floppy disk requires an unsupported driver under TOPS-10 and
|
||||
is not supported under TOPS-20 or ITS.
|
||||
|
||||
The RX211 implements these registers:
|
||||
|
||||
name size comments
|
||||
|
||||
RYCS 16 status
|
||||

|
||||
|
||||
not attached 1 report error and stop
|
||||
0 disk not ready
|
||||
|
||||
RX02 data files are buffered in memory; therefore, end of file and OS
|
||||
I/O errors cannot occur.
|
||||
|
||||
2.13 DEUNA/DELUA Ethernet Controller (XU)
|
||||
|
||||
XU simulates the DEUNA/DELUA Ethernet controller. The current implementation
|
||||
is a stub and is permanently disabled.
|
||||
|
||||
2.14 Symbolic Display and Input
|
||||
|
||||
The PDP-10 simulator implements symbolic display and input. Display is
|
||||
controlled by command line switches:
|
||||
|
||||
-a display as ASCII character
|
||||
-c display as (sixbit) character string
|
||||
-p display as packed (seven bit) string
|
||||
-m display instruction mnemonics
|
||||
-v interpret address as virtual
|
||||
-e force executive mode
|
||||
-u force user mode
|
||||
|
||||
Input parsing is controlled by the first character typed in or by command
|
||||
line switches:
|
||||
|
||||
' or -a ASCII character
|
||||
" or -c sixbit string
|
||||
# or -p packed seven bit string
|
||||
alphabetic instruction mnemonic
|
||||
numeric octal number
|
||||
|
||||
Instruction input uses standard PDP-10 assembler syntax. There are three
|
||||
instruction classes: memory reference, memory reference with AC, and I/O.
|
||||
|
||||
Memory reference instructions have the format
|
||||
|
||||
memref {@}address{(index)}
|
||||
|
||||
memory reference with AC instructions have the format
|
||||
|
||||
memac ac,{@}address{(index)}
|
||||
|
||||
and I/O instructions have the format
|
||||
|
||||
io device,{@}address{(index)}
|
||||
|
||||
where @ signifies indirect. The address is a signed octal number in the
|
||||
range 0 - 0777777. The ac and index are unsigned octal numbers in the
|
||||
range 0-17. The device is either a recognized device mnemonic (APR, PI,
|
||||
TIM) or an octal number in the range 0 - 0177.
|
||||
|
||||
The simulator recognizes the standard MACRO alternate mnemonics (CLEAR
|
||||
for SETZ, OR for IORI), the individual definitions for JRST and JFCL
|
||||
variants, and the extended instruction mnemonics.
