Appendix B) and press "F1" keys to cause the system to "AUTO Boot", the system will display the message : TATUNG DOS VERS V.W* and then the symbol "A>" will appear. This is the indication that the Operating System program has successfully loaded and is controlling the commands to perform the processing required. -
Page 14: System Description
The TATUNG TPC-2000 Integrated desktop microcomputer system is a single user system, it is a compact and very attractive desktop unit. The standard system consists of the processor unit, CRT display, detachable keyboard and dual slim line mini-floppy disk drives. -

The ROM firmware will be considered a subset of the software, since it is program material. The program in the ROM was written by TATUNG and is required in order to perform the most basic machine functions. -
Page 17: Cp/M Operating System
CP/M OPERATING SYSTEM General Description CP/M is a monitor control program for microcomputer system development w h i c h uses IBM-compatible f l e x i b l e disks for backup storage. C P / M provides a general environment for program construction, storage, and e d i t i n g , along w i t h assembly and program check-out facilities. -
Page 18: Function Description Of Cp/M
WRITE Write a record onto the disk. SELECT Select a particular disk drive for further operations. The CCP provides symbolic interface between the user's console and the r e m a i n d e r of the C P / M system. The CCP reads the console device and processes commands which include listing the file directory, printing the contents of files, and controlling the operation of transient programs, such as assemblers, editors, and debuggers.. -
Page 19: File References
in disk A, prompts the user with the symbol "A>" (indicating that CP/M is currently addressing disk "A"), and waits for a command. The commands are implemented at two levels: built-in commands and transient commands. Nearly all of the commands reference a particular file or group of files. - Page 20 ppppppp. are abbreviations for As an example, is interpreted by the CCP as a command to list the names of all disk files in the directory, while DIR X.Y searches only for a file by the name X.Y . Similarly, the command DIR X?Y.C?M causes a search for all (unambiguous) file names on the disk which satisfy this ambiguous reference.
-
Page 21: Switching Disks
Switching Disks The operator can switch the currently logged disk by typing the disk drive name (A,B,C,orD) followed by a colon ( : ) when the CCP is waiting for console input. Thus, the sequence of prompts and commands shown below might occur after the Cp/M system is loaded from disk A: A>DIR List all files on disk A. -
Page 22: Dir Afn
ERA *.ASM All files with secondary name ASM are removed from the current disk. ERA X?Y.C?M All files on the current disk which satisfy the ambiguous reference X?Y.C?M are deleted. ERA *.* Erase all files on the current disk (in this case the CCP prompts the console w i t h the message "ALL FILES (Y/N)?"... -

device and the console device until the next ctl-P is typed. ctl-S Stop the console output temporarily. Program execution and output continue when the next character is typed at the console (e.g., another ctl-S). This feature is used to stop output on high speed consoles, such as CRT's, in order to view a segment of output before continuing. -
Page 26: Stat
Transient commands are specified in the same manner as built-in commands and additional commands can be easily defined by the user. As an added convenience, the transient command can be preceded by a drive name, which causes the transient to be loaded from the specified drive into the TPA for execution. -

The two-pass assembler is automatically executed. If assembly error occur during the second pass, the errors are printed at the console. The assembler produces a file X.PRN where x is the primary name specified in the ASM command. The P R N file contains a listing of the source program ( w i t h imbedded tab characters if present in the source program), along with machine code generated for each statemnt and diagnostic error messages, if any. -
Page 29: Pip
The LOAD command creates a file named which marks it as containing machine executable code. The file is actually loaded into memory and executed when the user types the file name x immediaietly after the prompting character ">" printed by the CCP. - Page 30 2) PIP "command line" <cr> In both cases, PIP is loaded into the TPA and executed. In case ( 1 ) , PIP reads command lines directly from the console, prompting with the carrige r e t u r n is issued by the operator). Each successive command line causes some media conversion to take place according to the rules shown below.

- Page 35 used to "abstract" a particular section of a file (such as a subroutine). The start and quit string s are always included in the copy operation. NOTE the string s following the S and Q parameters are translated to upper case by the CCP if form (2) of the PIP command is used. Form (1) of the PIP invocation, however, does not perform the automatic upper case translation.

The SUBMIT function creates a file of substituted commands with the nae on the logged disk.

which are executed in sequence by the CCP. The SUBMIT function can access a SUB file which is on an alternate drive by preceding the file name by a drive name. Submitted files are only acted upon, however, when they appear on d r i v e A. Thus, it is possible to create a submitted file on drive B which is executed at a later time when it is inserted in drive A. - Page 42 Construct a relocated memory image for an n kilobyte memory system, and leave the memory image in preparation for a SYSGEN operation.

REFORM The REFORM utility prepares a new diskette for use in your TPC-2000 in either IBM standard single density format or TATUNG double density format.

It is strongly recommanded that you make backup copies of all your disks. If a disk becomes damaged or if files are accidentally erased, you will still have all of the information on your backup disk. You can back up disks by using the TATUNG TPC-2000 DCOPY command.
