Library 9 TDDTEK.CAT CMDS01.TDD [70235,232] 08-Sep-86 9305 A beginning command set to run the TDD from standard BASIC without any special DOS. This is a runnable tutorial program, heavily commented, and includes STATUS, DIRECTORY, OPEN (R W A), CLOSE, GET/PUT DATA and FORMAT. Much more work is needed and all are invited to contribute: messages to Woods Martin 70235,232. While not yet practical, it is fun. CAUTION - the EAT DISK command is bound to exist. DISKIT.100 [73126,1775] 05-Apr-86 615 Designed for users of the Tandy Disk Drive with PWR-DISK and PCSG's Four Bank Ram Upgrade (128K Ram Upgrade). It is a sample program which demonstrates the ram hook pokes necessary to access both disk files and files in other banks within the same program or to run a program directly off disks which then accesses other files in other banks. See DISKIT.DOC DISKIT.DOC [73126,1775] 05-Apr-86 9560 Documentation for DISKIT.100 DOSTIP.001 [75775,1430] 02-Oct-86 750 A short tip on how to use Powr-Dos by Acroatix to load Supera (and, presumably, the PG Ram bank switcher). DOSTIP.002 [75725,1134] 03-Oct-86 680 A second solution to the obviously vexing problem of how to load another LOMEM occupant with Acroatix' Powr-DOS. DOSTIP.003 [71266,125] 11-Oct-86 2465 Discusses the possibility of partitioning TDD sectors by using the DSKO$ command of POWR-DOS. Of interest to current and potential owners of POWR-DOS. DOSTIP.004 [75775,1430] 25-Oct-86 1275 Contains three very short programs allowing Powr-Dos users to peek around individual sectors. Does not require machine-language or hexidecimal knowledge. Also mentions a small conflict with Supera keysets. DOSTIP.005 [75725,1134] 14-Oct-86 875 List of files on the Powr-DOS distribution disk. Provided because there's no such list in the package. DOSTIP.006 [72457,3343] 23-Oct-86 940 Bugfix for the MERGE bug on early versions of POWR-DOS. DOSTIP.007 [75725,1134] 11-Nov-86 780 A safer way to make a program check for the presence of Powr-DOS DOSTIP.008 [75725,1134] 17-Nov-86 2005 Essay on the risks and payoffs involved in PEEKs & POKEs to learn how TDD (and everything else about this computer) works. DOSTIP.009 [75725,1134] 04-Jul-88 4958 Powr_DOS provides TDD1 users the capabiltiy to bypass the TDD file structure and access the disk directly. The most obvious applications for this capability are utility programs and database programs. This file lists all-in-one-place those things someone writing such a program will need to know. This is an advanced and fairly specialized programming tip. TDD2/FLOPY2 users/programmers should read, instead, TD2TIP.009, which covers the same matters. DOSTIP.010 [75725,1134] 02-Aug-88 3027 I've said before that RECOVR is worth the price of admission for Powr-DOS; I'm certainly not going to retract the claim now that the program's "free". Nonetheless, RECOVR has some irritating quirks. The patch enclosed in this file fixes some of them. This file includes the patch, some discusion, and instructions for loading the patch. DOSTIP.011 [75725,1134] 01-Aug-88 1042 The Powr-DOS command set includes the command LFILES MENU. A couple notes on why it's preferable to MENU for a program exit. DOSTIP.ER6 [74756,413] 31-Jan-87 415 Correction to apparent typographical error in DOSTIP.006. Partial fix of MERGE/LOAD [ASCII] bug in POWR-DOS. DPTIP.000 [73327,2262] 30-Jul-86 600 Introduction to the DISK POWER DPTIP.xxx series, placed on Compuserve by Ultrasoft Innovations Inc. for all users of the Tandy or Brother FB-100 portable disk drive. These tips will help DISK POWER owners to better use their Disk Operating System with various other machine language programs, hardware and peripherals. The series will also address some of the inherant shortcomings of the PDD and will offer solutions at different user levels. DPTIP.001 [73327,2262] 30-Jul-86 2350 First in a series of tips for users of all levels with DISK POWER and the Tandy/Brother Portable Disk Drive. This tip deals with the use of DISK POWER and ACOUSTIC COUPLERS to upload and/or download to disk (indirectly), without the need of any hardware or software modifications, while connected to TELCOM (TERMinal mode) and without losing the carrier or telephone line. DPTIP.002 [73327,2262] 30-Jul-86 1100 The 2nd in a series of tips for users of DISK POWER and Tandy/Brother Portable Disk Drive. In this tip, we will be addressing the problem of the drive to not allow files greater than 64K in length, and some suggestions on how to avoid data loss due to this problem of the drive. DPTIP.003 [73327,2262] 14-Aug-86 2180 Tip number three in the ongoing DPTIP.xxx series, for users of the Tandy/Brother Portable Disk Drive and DISK POWER. This tip deals with user documentation clarifications and additions of some omitted material. (for version one only of the manual, since all new users get the updated manual, version two). DPTIP.004 [72300,3203] 28-Mar-88(28-Mar-88) 5175 For the users of the 100/102, Tandy Disk Drive 100k (TDD1), with DiskPower and SUPERA Version 3.0. It contains information about a patch to enable the two to operate simultaneously without resulting in a cold start. DPTIP.005 [72300,3203] 30-Mar-88 1207 For the users of the 100/102, Tandy Disk Drive 100k (TDD1), with DiskPower and SUPERA Version 3.0. It contains a much shorter version of the program given in DPTIP.004 for a patch to enable the two to operate simultaneously without resulting in a cold start. DPUSER.000 [73327,2262] 19-Aug-86 1125 DPUSER.xxx is a new series of tips, comments and other useful information from USERS of DISK POWER 100/102/200. The files talk about DISK POWER performance under operating conditions never thought of by its' designer. DPUSER.000 explains the philosophy behind the series. For tips fully supported by Ultrasoft Innovations, please see the DPTIP.xxx series. DPUSER.001 [71266,125] 19-Aug-86 3650 Contains some (hopefully) intelligent guesses about how Disk Power 100 is implemented, and some cautionary notes based on these speculations. See DPUSER.002 for some good hints on using other OS's. DPUSER.002 [73537,775] 22-Aug-86 3585 One users opinion of Disk Power after a few weeks use. Includes discussion and program to use other operating systems with Disk Power. DPUSER.003 [70136,1007] 23-Aug-86 2900 The Disk-Power documentation has an "undocumented" explanation of how one can load or save files to/from the TDD while in the F7-called text mode of Telcom -- but only with the acoustic cup connection. This tip reports that the Model 200 supports the direct-connect cable as well -- at least while online to CompuServe and other services that don't shut down after short pauses. MAPTDD.100 [75725,1134] 12-Oct-86 1735 Program uses Powr-DOS's DSKO$ to pull all the file-control information from a TDD diskette. This program is mainly useful as the basis for another. MAPTDD.DOC [75725,1134] 12-Oct-86 4585 Documentation for MAPTDD.100. Powr-DOS required POWR-D.TD2 [71266,125] 19-Jul-87 1942 POWR-DOS is a TDD1 OS which works with the TDD2 in all but its sector access mode (which is a built-in FLOPPY2 feature, anyway). But Powr-Dos cannot be booted from the TDD2. This file tells how to make it feasible to load Powr-Dos from the TDD2. An added feature is that you do not need to use your Powr-Dos distribution disk again -- once you have followed the steps here. And the same approach will work for back-up purposes with the TDD1. PWRDSW.100 [74756,413] 27-May-86 1545 A simple approach to memory conflicts between POWR-DISK and ML programs suitable for most purposes. PWRTIP.001 [75725,1134] 16-Jun-88 6193 For the benefit of the uninitiated, a quick description of Powr-DOS and some suggestion of why someone might want to acquire it. PWRTIP.002 [75725,1134] 15-Jun-88 4435 TINY.PWR (one of the POWR-DOS files) is a *very small* file transfer utility for the Model 100/Tandy 102 and the TDD/TDD2. IT DOES *NOT* REQUIRE POWR-DOS OR ANY OTHER OPERATING SYSTEM. If that's what you need, this is the program you need. The advantage, of course, is that nearly all of your RAM remains available for other applications. Mostly, this file contains those excerpts from the Powr-DOS manual which pertain to TINY. PWRTIP.003 [75725,1134] 01-Aug-88 1581 Among the Powr-DOS files is a very capable file recovery program. This TIP describes it and tells which files to pick up. SECDOS.TDD [75775,1430] 07-Oct-86 1340 SECTORUse with Powr-Dos by Acroatix. Creates a RAM file with disk directory including file lengths and START and END sectors. Of special interest to those starting to study and use DSKO$. SECTR0.TDD [75725,1134] 15-Nov-86 12040 Map of the Directory Sector (0) of the TDD disk. Also other information about how TDD manages files. This information mostly acquired with the help of the DSKO$ command in Acroatix' Powr-DOS. See DOSTIP.008 for additional discussion. SUPER.PD [71266,125] 10-May-86 1210 A short "how to" file for use of Super ROM with POWR-DISK. Note that the example of use of 'CALL MAXRAM' in a program is only one way to do it. The preferred approach for PDMENU is incorporated in V06 of that program. TD2TIP.001 [70136,1007] 02-Mar-87 2533 New TDD2? Here's two valuable tips -- yes, you can use Disk Power and Power-Disk from your old TDD...with a limit of 40 files. No, you can't power both TDD2 and M100/200 from your old wall transformer without risking a crash. TD2TIP.003 [70506,223] 04-Apr-87 5019 Some of my observations about the TDD2. Backing up TDD1 disks to the TDD2 using Copy.BA. Using Splchk.BA with only one dictionary disk. And a way to load Powr-DOS from the TDD2. TD2TIP.004 [73117,351] 07-Apr-87 1613 Observations and tips on use of new Tandy Portable Disk Drive, the TD2, or PDD-2 TD2TIP.005 [70506,223] 18-Apr-87 714 A breif overview of FLOPY2.CO and CALL 62297,Mode,Adr. The call is used by the basic program BACKUP.BA for the TDD2. TD2TIP.006 [71266,125] 15-Jul-87 1440 Includes a patch to modify the TDD OS for compatibility with Low-RAM resident programs such as 0MENU, SUPERA and Tony's MACRO program. TD2TIP.007 [71266,125] 17-Jul-87 1508 Discusses the use of DSKMGR.100/200 with the TDD2. Capabilities, limitations and cautionary notes are the topics. TD2TIP.008 [71266,125] 19-Jul-87 1683 There is a fair amount of interest in TDD1-TDD2 disk compatibility. This note reports some tests, conducted with DSKMGR.REL, and repeated with two version of TS-DOS with the same results. TD2TIP.009 [75725,1134] 04-Jul-88 10179 FLOPY2 provides TDD2 users the capabiltiy to bypass the TDD file structure and access the disk directly. The most obvious applications for this capability are utility programs and database programs. This file lists all-in-one-place those things someone writing such a program will need to know. This is an advanced and fairly specialized programming tip. TDD1/Powr-DOS users/programmers should read, instead, DOSTIP.009, which covers the same matters. TD2TIP.015 [76703,4062] 03-Oct-89 590 IPL loading instructions for the TDD-2 TDDINF.TIP [76703,4062] 03-Oct-89 10210 The TDD-2 (Tandy Portable Disk Drive - version 2) is currently the only disk drive still available for use with the Tandy line of portable computers, the Model 100/102 and Tandy 200. This is a captured message thread discussing some aspects of it's technical capabilities. TDDTIP.002 [75715,100] 24-Oct-85 1830 Use 3.5K of the memory taken up by the DOS .CO file when not in use. Easy to install DOS and to remove DOS. Will not conflict with other M/Language Programs. Also will not "bomb" the computer if Drive is not turned on when DISK.BA is selected. TDDTIP.003 [75776,3061] 27-Oct-85(30-Oct-85) 3010 Identifies the disk controller chip in the new Tandy drive, and speculates about a new operating system which would make the drive more responsive. TDDTIP.005 [73016,1336] 03-Nov-85 1145 This message and short program guide a user in changing the function menu for the new Tandy Portable Disk file manager so that the function key labels are in the expectied locations. TDDTIP.006 [71266,125] 04-Nov-85 2215 Describes how to modify FLOPPY.CO for operation with the PG Designs 64K RAM MENU utility -- and probably with SUPERA, as well. It also describes my approach to using the drive with multiple banks of RAM. TDDTIP.007 [71266,125] 16-Nov-85 2725 Discusses the use of a commercial program, FUTIL (from TMPC package) to make use of FLOPPY.CO in conjunction with other M/L programs more convenient and memory-efficient. TDDTIP.008 [73226,3504] 21-Nov-85 4095 An update to TDDTIP.008, with some added information on formatting the function key labels. It includes all the information in the prior file, and adds the program checksums. TDDTIP.009 [73016,1336] 23-Nov-85(23-Nov-85) 1525 A brief note on labeling and using function keys to CALL the Disk File System and MultiPlan. TDDTIP.010 [72246,355] 21-Dec-85 8225 Recovery of DVI RAM using both DVI & TDD with Model 100. TDDTIP.011 [70235,232] 28-Dec-85 425 TDDTIP.005 includes a short program to modify the Tandy Portable Disk Drive control program FLOPPY.CO to give a more conventional and pleasing Menu display. Ches's fine program is repeated here with the addition of code to automatically load FLOPPY into high memory and to then save the modified program as a RAM file. Ches's program name FXMENU is included in the display. TDDTIP.012 [73016,1336] 11-Feb-86 2865 Short program description and listing for displaying 16 TDD file titles and lengths on the Model 100 screen instead of the usual seven. Differs from other menu approaches in being limited to the displaying of disk contents only. TDDTIP.013 [71266,125] 21-Aug-86 655 How to boot the TDD from Ultimate ROM II, without needing to own TS-DOS. Tested with the Model 100, but should work for the Model 200. TDDTIP.014 [76703,4062] 15-Jul-88 1138 "Truth Table" defines various baud rates and test positions of the four dip switches in the bottom of the Tandy/Brother Portable Disk Drive. (TDD-1 or PDD-1) TDDTIP.015 [76703,4062] 15-Jul-88(02-Oct-88) 1395 Discuss why Tandy's IPL.BA code is not in the forum library, and where you can find a copy; and how to use it to load FLOPPY.CO from the TDD-1 utility disk into the computer. USCTIP.001 [73117,351] 27-Aug-87 878 Using UltraScreen 1.1 from a Tandy disk drive 1 or 2
