PDSK01.200 Copyright 1988 Tony B. Anderson All Rights Reserved This is the first of a series of files which contain POWR-DISK.200, a DOS (Disk Operating System) for the TDD-1 (100K version), and the Tandy 200 computer; and the necessary documentation and instruction manual for the software. POWR-DISK, and all it's related programs and files are copyrighted by Acroatix Incorporated, and all the programs and files are so marked. They have released this series of programs for public access exclusively on the CompuServe Model 100 Forum for the exclusive use of its members. All other Rights are Reserved. POWR-DISK is a transparent DOS that loads into high memory, and moves MAXRAM down to protect itself from other machine language programs, and becomes trans- parent to the user. The basic "kernal" of the program, POWR-D.CO, provides access to disk files from BASIC and TEXT, and via POWR-DISK routines, to other machine language programs. It is also relocatable to accomodate other machine language programs that may cause machine language conflicts. Five of the files contain hex datafiles which must be converted into standard .CO files with the HXFER program (HXFER.200 in Library 10), or with a relocated version (HXFER.REL). See the instructions for HXFER use in the file HXFER.DOC. All related files in the forum library may be listed with any form of the SCAN or BROwse commands using "PDSK*" as the filename. SCA PDSK* or BRO PDSK*. Following is a list of the files available, listed in the order in which they should be read and/or downloaded. 1. PDSK01.200: This file; describes POWR-DISK.200, the files that are part of the system, and the release conditions by the copyright holder. 2. PDSK02.200: The complete manual for POWR-DISK.200. The file contains embedded Top-of-Form commands for proper paging, and should be echoed to a printer to obtain a complete copy of the manual. The file is 63K bytes, and will print on approximately 28 pages. Echoing to your printer at 300 baud should take about 45 minutes. If you have a desktop computer, or one with more RAM space available, you can download the file for later reference or printing. You can also read, echo or download the manual in seven segments of 11K or less, so they will fit in RAM. They can then be saved to an external device or printed as part of a complete manual. The segmented manual is contained in the seven files PDSKM1.DOC to PDSKM7.DOC. These files contain the same information that is contained in PDSK02.200. 3. PDSK03.200: This file contains all you really need to get the basic POWR- DISK operational in a Tandy 200. It contains a hex datafile of the machine language routines in POWR-D.CO, and a BASIC loader and start-up program called START.BA. Convert the hex datafile into a .CO file with HXFER, and run START to load and execute POWR-DISK. THE REST OF THE FILES LISTED BELOW ARE OPTIONAL, DEPENDING ON WHAT OPTIONS YOU CHOOSE; RELOCATED VERSIONS, BASIC LOADERS, AND A MAP OF THE DOS ROUTINES. 4. PDSK04.200: This file contains an expanded version of START.BA, with all the bells and whistles of the original version on the release disk. It is not necessary that you download or read this file if you elect to use the shortened version in the PDSK03 file. 5. PDSK05.200: This file contains the hex datafile which is converted into POWR-D.CO by HXFER. It is the same version found in the PDSK03 file, and if you elect to use the short method of getting started (in PDSK03), you will not need to download or read this file. 6. PDSK06.200: This file contains the POWR-DISK menu program, MENU.BA, which provides a menu access system to disk files. It uses 3.5K of RAM, and is not necessary to use the POWR-DISK system. Most of the functions of the program can be duplicated from BASIC or TEXT with direct commands. 7. PDSK07.200: This file contains a program called FLOPPY.BA which will run a copy of FLOPPY.CO directly from a pre-saved copy on disk. It clears RAM space, loads a relocated version of POWR-DISK, which can them be used to load FLOPPY.CO into it's normal executing position. The relocated code is stored in the PDSK09 file. 8. PDSK08.200: This file contains MPLAN.BA which is not documented in the POWR-DISK manual. It's apparent purpose is to run a relocated version of POWR- DISK which does not conflict with the Tandy 200's version of MSPLAN. The relo- cated code is stored in the PDSK10 file. 9. PDSK09.200: This file contains a hex datafile which becomes PD-FLP.CO after conversion by HXFER. This file is a companion to PDSK07. 10. PDSK10.200: This file contains a hex datafile which becomes PD-MPL.CO after conversion by HXFER. This file is a companion to PDSK08. 11. PDSK11.200: This file contains a BASIC relocator program, which can create a relocated version of POWR-DISK at any location in RAM. The program name is RELOC.BA. It's two companion files are RELO.DO in PDSK12, and POWR.CO in PDSK15. 12. PDSK12.200: This file contains a copy of RELO.DO, a file which is required by the RELOC.BA relocating loader. 13. PDSK13.200: This file contains a copy of RESTOR.BA, a program which will "Restore" a normal version of POWR-DISK after running a relocated version at another address. 14. PDSK14.200: This file contains a map of the POWR-DISK routines which may be "called" by other machine language programs, thus providing disk access from those programs. 15. PDSK15.200: This file contains a hex datafile of POWR.CO, the relocatable version of POWR-DISK. After converting with HXFER, this file, along with RELO.DO (PDSK12), is used by RELOC.BA (PDSK11) to create a relocated version at any address you choose. The complete version of POWR-DISK.200 is contained in these 22 files. For those forum members who have Model 100's or 102's, we suggest they use the POWR-DOS system, which is an upgraded version of POWR-DISK, with additional capabilities and functions. Those files, in Library 9 of this forum, can be located by scanning for files with the keyword P-DOS. The command SCA KEY=P-DOS will provide a list of the relevant files. On this forum, POWR-DISK is only available for the 200, while POWR-DOS is only available for the 100/102. While POWR-DOS is a superior version of POWR-DISK, we were unable to obtain a copy from Acroatix Inc. to release into the public domain.
