PREFACE
This supplement to the Model 990 Computer Prototyping System Operation Guide describes an
enhancement of the TMS 9900 Prototyping System, defined as the Prototyping Monitor (PX)
with Resident Assembler, Tracer, Linking Loader, and Editor (PXRATE). This supplement
documents changes to the TMS 9900 software modules which now comprise the PXRATE
system. It also describes the hardware required to support the PXRATE system.
This manual is intended for users of the TMS 9900 Prototyping System software and for users
who require the capability to generate, edit, assemble, load, and debug user application programs
and generate firmware for the 990/4 Computer, the 990/10 Computer, and the TMS 9900
Microprocessor. It is also intended for users who desire to perform input/output operations on
the 733 ASR Data Terminal to/from peripheral devices.
This manual is divided into four sections and one appendix as follows:
I

General Description - Describes the PXRATE software and the hardware needed to
support it.

II

System Installation and Operation - Gives the sources of information on unpacking,
installing, and operating the supporting hardware. Provides step-by-step procedures for
PXRATE system software cassette generation.

SECTION I
GENERAL DESCRIPTION
1.1 INTRODUCTION
This supplement to the Model 990 Computer Prototyping System Operation Guide documents an
enhancement of the TMS 9900 Prototyping System, defined as the Proto typing Monitor (PX)
with Resident Assembler, Tracer, Linking Loader, and Editor (PXRATE). This section presents
an overview of the enhanced software and the hardware required to support it. The first portion
of the section describes the purpose and capabilities of the enhanced software and identifies the
hardware. The remainder of this section briefly describes changes to the modules that comprise
the enhanced system software. These modules include the debug monitor and its overlays, the
text editor, and the one-pass assembler.
1.2 PURPOSE AND CAPABILITIES OF THE ENHANCED SYSTEM (PXRATE)
The enhanced TMS 9900 Prototyping System software augments the capabilities of the TMS
9900 Prototyping System software. The original system is documented in the Model 990
Computer Prototyping System Operation Guide, Manual Number 945255-9701. User familiarity
with the original system documentation and operation is prerequisite to this supplement. The
PXRATE system requires a minimum memory size of 12K words. In this 12K, all software
development/debug capabilities are coresident (text editor, assembler, linking loader, trace, and
program debug). Coresidency of these capabilities negates the time-consuming process of reloading (from cassette) the appropriate utility between program development steps. This coresident
package of software also supports the use of the Model 33 ASR Data Terminal paper tape
reader/punch.
1.2.1 DESCRIPTION OF SYSTEM ENHANCEMENTS. The purpose of the PXRATE prototyping system software is to provide the capability to generate, edit, assemble, load, and debug
user application programs and to generate firmware. The PXRATE package also includes a Device
Service Routine (DSR) which supports the use of a TTY paper tape reader/punch. The former
instruction trace overlay is no longer an overlay, but is now a command in the resident monitor.
In addition to the debug functions, the debug monitor provides supervisor calls to perform
input/output 0/0) operations on the 733 ASR Data Terminal and utility routines, such as
decimal ASCII to binary, hexadecimal ASCII to binary, binary to decimal ASCII, and binary to
hexadecimal ASCII conversion. Overlays to the debug monitor provide the capability to dump/
reload a program from/to memory to/from tape in a compressed absolute format. In addition,
monitor overlays are provided to support the PROM Programmer Package and BNPF (or
HIGH/LOW) formatted dumps to cassette tape or to paper tape. The BNPF overlay also provides
the capability to load tape in BNPF format back into memory.
The PXRATE system software is available in object format on a read-only magnetic tape cassette
and in source format on punched cards; however, the system source must be assembled and
linked using a 990/10 Program Development System. The PXRATE system software provides the
capability to generate source and object which is upward compatible with other 990 systems. See
Appendix A of Model 990 Computer Pro to typing System Operation Guide for restrictions.

1.2.2 HARDWARE CONFIGURATION REQUIRED FOR PXRATE SYSTEM SOFTWARE. The
hardware required for the PXRATE proto typing system is the same as that described in the
Proto typing System Manual except that a minimum of 12K words of memory is required in the
enhanced system. See figures 1-1 through 1-4 for detailed memory requirements of systems with
12, 16, 20, and 24K words of memory. Part of the user area of the memory is shared by the
text editor and the one-pass assembler for tables and buffer space.
The Model 33 ASR teletypewriter may be configured as an optional peripheral (TTY lElA Kit,
Part Number 974704-0002). It may not be used as the system console. The int~rface card must
be inserted in the left half of computer chassis slot 6, corresponding to CRU base address 20 16 ,
1.3 SYSTEM PART NUMBERS
Refer to Manual Number 945255-9701, paragraph 1.3, page 1-5.
1.4 SOFTWARE MODULES
In the PXRATE proto typing system, the debug monitor, trace capability, text editor and the
one-pass assembler have been combined into one module. In addition, when PXRATE is initially
loaded, the linking loader overlay is automatically placed in the overlay area. This software
package now becomes coresident in memory. The instruction trace overlay now becomes a part
of the monitor and is no longer an overlay. The PXRATE package is supplied on cassette tape.
Two new commands now reside in the coresident package. These commands are PA to activate
the one-pass assembler, and TE to activate the text editor. No parameters are necessary for either
command. Following the invocation of either of these commands, the operation of the assembler
or text editor is the same as described in Section IV of the Proto typing System Manual.
Activation and operation of the trace and linking loader has not been altered, except that no
overlay process is required prior to their use. Since the linking loader is located in the monitor
overlay area, it will be overwritten if another overlay is placed in memory, and must be reloaded
to be used again.

3.

Press CONT START (13). This causes the selected file to be recorded on the copy
cassette.

4.

After copying the PROM Programmer part 1, repeat step 4 to record the next file (PROM
Programmer part 2) onto the same cassette. Do NOT turn RECORD CONTROL to OFF
between these two files.

5.

Set RECORD CONTROL to OFF (5) to clear the buffer and record the last block of data
on the tape.

6.

Rewind and remove the copy cassette and label with the appropriate file name. Protect
tape side A from overwrite by setting write tab to uncover hole on bottom of tape for
side A (see figure 2-2).

7.

If there are any remaining overlay object files onPXRATE cassette 2, insert a blank

cassette into cassette drive 2. Rewind and ready blank cassette and repeat steps 2 through
6 (note that step 4 applies only to the PROM Programmer overlay). Continue this process
until each overlay is recorded on a separate cassette.
8.

Rewind and remove PXRATE cassette 2 and store it in a safe place.

The relocatable code version of PXRATE (table 2-1, cassette 2 side B) is supplied in the event
that the user would like to "custom place" the monitor in memory. The user must affIx the

CAUTION

It is possible for the user to overwrite the assembler, text editor,
and monitor by loading a user program larger than the available
user space (see figures 1-1 through 1-4). If this should happen,
reload the entire PXRATE package from the cassette tape.

SECTION III
TELETYPEWRITER INPUT/OUTPUT (I/O) SUPERVISOR CALLS
3.1 INTRODUCTION
This section describes the extension of prototyping system I/O supervisor calls to include
program I/O interface to the teletypewriter paper tape reader and punch (part of the Model 33
ASR Data Terminal). The user is referred to paragraph 3.5 of the Prototyping System Manual for
a general description of supervisor I/O calls. Read and write supervisor call codes are consistent
with those of the rest of the prototyping system.
3.1.1 HARDWARE (MODEL 33 ASR DATA TERMINAL). The Model 33 ASR Data Terminal
is an automatic send/receive teletypewriter. It has a paper tape reader and punch for automatic
input and output. The reader is a means of automatically entering programs that are on punched
paper tape. The punch is a means of recording object code output of the computer on paper
tape. File data of other types may be read or punched in a similar manner. The reader may be
put online for input, and the punch may be put online for output.
NOTE
The Model 33 ASR Data Terminal is supported as an optional
peripheral only. It may not be configured as the system console in
place of the 733 ASR terminal.
Data is punched on paper tape serially by character. The individual bits of each character are
aligned across the width of the tape and are punched in parallel. The hole in the tape represents
a one bit and the absence of a hole represents a zero bit. Data is transmitted and received
simultaneously (full duplex) over current loops in 7-bit ASCII for textual character or 8-bit code
for direct mode. The Model 33 ASR requires a Teletypewriter Peripheral Kit (ASR 3320/5JE
Interface), TI Part Number 974704-0002, which is supported by the computer CRU DSR and
I/O supervisor calls.
3.1.2 REFERENCES. For further information, refer to TTY/EIA Interface Module Installation
and Operation Instruction Manual, Section II, TI Part Number 946240-9701. A complete description of the Model 33 ASR may be found in Technical Manual, 33 Teletypewriter Sets, Volumes
1 and 2 (Bulletin 3l0B) and Model 33 Page Printer Parts (Bulletin l184B) supplied with the
teletypewriter. If your teletypewriter was not supplied by Texas Instruments, modifications are
necessary as outlined in the above referenced TTY /EIA Interface Module Installation and
Operation Instruction Manual.
3.2 ACCESS TO MODEL 33 ASR DATA TERMINAL
The PXRATE system accesses the TTY paper tape reader/punch by the invocation of supervisor
calls. A supervisor call is made with an extended operation (XOP) assembly language machine
instruction using an extended operation code of 15. The XOP instruction specifies an address
pointing to a Physical Record Block (PRB) containing the supervisor call and any necessary
arguments. The format of the PRB is illustrated in figure 3-1.
A detailed discussion of the PRB parameters is presented in paragraph 3.5.2 of the Prototyping
System Manual.

3.3 LOGICAL UNIT NUMBER (LUNO) ASSIGNMENT
Before execution of any supervisor call I/O operation, a LUNO must be assigned to the
particular peripheral device with which I/O communication is desired (refer to paragraph 3.4.2 of
the Prototyping System Manual).
With the Model 33 ASR Data Terminal, the device symbols and names of interest are:
PTR
PTP

Paper Tape Reader
Paper Tape Punch

An example of LUNO assignment is:

.AL,3,PTR
This assigns Logical Unit Number 3 to the paper tape reader, so that whenever LUNO 3 appears
in a PRB, the paper tape reader will be accessed through the execution of a supervisor I/O
operation. It should be noted that default LUNOs have not been provided for Model 33 ASR
Data Terminal support (refer to paragraph 3.4.2 of the Prototyping System Manual).
3.4 OPERATION CODE (OPCODE) INTERPRETATION
The monitor's interpretation of the various opcodes in the PRB depend upon the particular
teletypewriter device being accessed. The following two paragraphs describe those interpretations.
3.4.1 PAPER TAPE READER. The functions of the possible opcodes for the tape reader are
described in table 3-1.
3.4.2 PAPER TAPE PUNCH. The functions of the possible opcodes for the tape punch are
described in table 3-2.
3.5 ERROR RETURNS
Error detection is performed by the Device Service Routine (DSR) with meanings as defined in
table 3-3.
When a supervisor call causes one of these errors to occur, the code is returned in the user flags
byte of the PRB (see figure 3-1).

Read ASCII

If reader flag is set, data is read from the paper tape. Termination
is caused either by a carriage return or user's buffer full. Only seven
bits of data are transferred to the user's buffer with the eighth bit
(parity) ignored. At termination the tape continues until a readeroff character is sensed, during which no data is stored. The number
of characters read is returned to the user's character count.

A

Read Direct

Checks if reader flag is set. If set, data is read until the first non-null
frame is encountered. Termination is caused by user's buffer full,
and tape continues to pass until a reader-off is sensed during which
no data is stored. The number of characters read is returned to the
user's character count.

3.6 PAPER TAPE FILE AND DATA FORMATS
Two types of paper tape I/O are supported: ASCII and Direct. The type of data to be punched
or the interpretation of the data to be read depends on the particular type of opcode used (see
Opcode Interpretation, paragraph 3.4).
3.6.1 ASCII. This type of data represents characters in ASCII 7-bit code. ASCII mode is used
for storing and retrieving character information. The ASCII paper tape format and an actual
paper tape sample are illustrated in figure 3-2.

tape. A hole represents a one bit and lack of a hole represents a zero bit. It is used for storing
and retrieving binary data on paper tape. The Direct paper tape format and an actual paper tape
sample are illustrated in figure 3-3.

SECTION IV
DEMONSTRATION OF THE PXRATE SOFTWARE PACKAGE
4.1 SAMPLE PROGRAMS
Sample programs I and 2 exist in the Prototyping System Manual. These programs may be used
with the PXRATE system. A minimum of 4K-word user memory space is required with sample
program 2. Therefore, at least a 16K-word memory prototyping system is required for sample
program 2.
Three new sample programs (numbers 3, 4, and 5) are presented in this section. Sample
program 3 illustrates the use of the PXRATE system in the development of a short user program.
Sample program 4 demonstrates the use of supervisor I/O calls on the Model 33 ASR Data
Terminal paper tape reader and paper tape punch. Sample program 5 demonstrates the use of the
BNPF utility overlay with paper tape instead of magnetic tape cassette.
These sample programs are presented with the assumption that the user has read the Prototyping
System Manual and this supplement to the manual, and has been introduced to the functions
used in these documents.
The source for sample programs 3 and 4 are provided on tape cassette; sample program 5
requires only the BNPF overlay.
Included in each of the following sample programs is a brief explanation of the procedure and a
listing of most, if not all, of the actual procedures followed. In some places, comments have
been added within computer printout reproductions. The following conventions are used in each
of the sample program listings:
•

Comments that explain to the user what to do or what is happening are delineated by
parentheses.

•

Keys that must be depressed on the log keyboard are indicated in the listings by an
underscore.

•

Angled brackets enclose a single key to be depressed; e.g., «CR» directs the user to
depress the carriage return.

,

4.1.1 SAMPLE PROGRAM 3, USER PROGRAM DEVELOPMENT. This program demonstrates
the use of the PXRATE system in the development of a user program. The source for this
program is supplied to the user on a cassette. The program takes a string of ASCII digits and,
given the radix, computes the binary value of the number. An intentional error has been
introduced into the program to demonstrate use of the PXRATE system to detect, locate, and
correct programming errors.
4.1.2 TEXT EDITOR. The user should ready the sample program cassette in the cassette 1
transport of the 733 ASR Data Tenninal and ready a blank cassette in the cassette 2 transport.
Now some comments are added to the source by means of the text editor. See figure 4-1.

4.3 SAMPLE PROGRAM 5, BNPF USE WITH PAPER TAPE
This procedure illustrates use of the BNPF overlay to dump and load data to and from paper
tape in BNPF format. Since the BNPF utility always dumps to LUNO 7 (normally cassette
drive 1), reassign LUNO 7 to the paper tape punch for dumps to paper tape or to paper tape
reader for loads (or compares) from paper tape. See figure 4-16. A reproduction of the resultant
tape can be seen in figure 4-17. A teletypewriter listing can be seen in figure 4-18.

END OF RECORD: CR for ASCII, DC3 for Direct
END OF FILE: DC3 for ASCII, does not apply for Direct
CHARACTER SET: As shown in figure A-I
1.

HT, FF, BEL, BS, and characters in the range >20 to >7F are stored in the user's
buffer.

2.

ETB is translated to CR and stored in the user's buffer.

3.

CR indicates end of record and is not stored in the user's buffer.

4.

DC3 received as the first valid character of a record indicates end of file and is not
placed in the user's buffer.

5.

The sequence LF, or DEL or LF,DEL or any number of nulls at the beginning of a
record are ignored if present. The first character following such a sequence is considered the first valid character in the record.

6.

In direct mode, the contents of a physical block on tape is transferred to the buffer
without conversion.

ASR 33
PERIPHERAL: ASR 33 TTY Paper Tape Punch (ASCII, Direct)
PHYSICAL ORGANIZATION: Character, Record, File
END OF RECORD: Depletion of Character Count
END OF FILE: DC3 for ASCII, does not apply for Direct
CHARACTER SET: As shown in figure A-2
1.

HT, FF, BEL, BS, and characters in the range 20 16 to 7F 16 are output as is.

2.

CR in the user's buffer is translated to ETB and output.

3.

The end of record character sequence is CR, LF, DC3, NULL, NULL, NULL, NULL.
These characters are automatically output to control the paper tape and are not user
data characters.

4.

The end of file character sequence is DC3, CR, LF, DC3, NULL, NULL, NULL.

5.

DC3 is allowed within a record for compatibility with standalone software. It may not
be written, however, as the first data character in the record.

6.

In direct mode:
•

Data is output unconverted; entire ASCII set is valid.

•

The end of record character sequence is DC3, NULL, NULL, NuLL.

•

If DC4 is encountered in the user's buffer, it is output and record is turned on
again by sending DC2.

•

The user is responsible for ensuring that last block is dumped to cage.

•

The end of record character sequence is output at the end of each write operation
by the DSR.
