Help categorize the TRS-80 software archive
Nearly 30,000 programs, and almost none of them say what kind of program they are. Mark whatever you recognize. Pick as many words as fit — a game that teaches arithmetic is Game, Math, Education — then send the page. Everything is reviewed by hand before it goes anywhere near the archive, so a best guess is worth more than a blank.
Important Note: Do not do multiple entries of the same program. If you flag Super Nova by Big Five once, all Super Nova by Big Five entries will get updated. No need to waste your time flagging each Super Nova

LDOS Utility Pack with Source CodeMISSING
LDOS Users! A special utility package just for YOU: DRIVE-5 Four drives not enough? DRIVE-5 is a memory based disk emulator which allows you to configure a fifth drive IN MEMORY! No moving parts, so access is FAST! In a two drive system, FORMAT and BACKUP can be placed on DRIVE-5 (with /SYS modules) to allow multiple backups with less disk swapping. LOWDUMP LOWDUMP allows you to DUMP files from anywhere in memory, including ROM and video RAM! LOWDUMP allows all parameters as the LDOS DUMP command, including ASCII, for dumping files without loader information present. SYSGEN SYSGEN/CMD allows you to save one or more SYSGEN files as normal /CMD files. Keep several configurations on the same disk and reload as necessary by simply typing the filename. Especially useful when the preferred configuration consumes so much memory that large programs will not execute properly. SYSGEN/CMD may also be executed from a running BASIC program. When the resultant /CMD file is executed, the BASIC program will continue with the next statement, all program variables intact! UNREPAIR Model I TRSDOS cannot read LDOS disks due to the F8 DAM used for directory sectors. UNREPAIR will rewrite the directory track of a single density disk using the FA DAM that will be recognized by Model I TRSDOS. UNREPAIR should run with any Model I DOS and the Radio Shack E/I. An extra BONUS! The TAS LDOS Utility pack includes Z80 source code (on disk) of most of the above utilities (the most informative). The LDOS Utility Pak is $49.95. This package was written by Les Mikesell.

JUST ANOTHER PRETTY DOS? If new LDOS were just another disk operating system (DOS), we would not recommend it to you. However, two differences make this system unique and important: customer support and user benefits. When you buy any DOS, you need service for programming assistance, updates and tips on how best to use its features. This is part of what you buy with LDOS. First, you will be supported by a toll-free phone line listed on your registration card. Second, you will be promptly notified of all updates and may send your original diskette to a service center for updating. You pay only the cost of return mail -- you can do it every week if you like. Third, a regular newsletter will inform you of any updates and provide tips on using some of LDOS's many special features. With LDOS you get a well documented, thoroughly tested, and powerful DOS. The publisher is committed to a professionally written and detailed users' manual. Besides contracting with some of the best microcomputer systems houses for technical and customer support, a highly regarded technical writing firm is doing the manual. The power of LDOS is its ease of operation, its independence of hardware configuration, and its device independence. You can make selected backups; chain together a series of programs and operations, and operate several different types of drives from the computer. LDOS has all the features of VTOS 4.0, fully implemented and working. There are hundreds of features which we do not have room to mention, but the best features are its ease of use for the new disk owner combined with its sheer power potential for the expert. We will gladly send you more information on LDOS if you just call our toll free number. LDOS with Manual $139

LDOS v5.1.2 [Sole Double Density]
ld1512m1.zip
45 LSI Catalog L-10-010 / L-10-030 LDOS 5.1 8970 North 55th Street/P.O. Box 23956/Milwaukee, WI 53223/(414) 355-5454 1984 LDOS 5.1 is the latest generation operating system for the TRS-80 computers. LDOS supports single and double density, single and double sided disk drives. All disk drive parameters may be adjusted to optimize performance on almost any given hardware. Both the PERCOM and Radio Shack types of double density adapters are supported on the Model 1. Disk formats are directly interchangeable between versions of LDOS 5.1, so files may be easily transported from one machine to another. The documentation for LDOS is both extensive and complete. The (over) 350 page manual covers almost every phase of daily operation, and comes with complete technical information. Many examples are given for almost all library commands and utilities. All the features of the LDOS system could not possibly be covered in this small space, but some of the highlights are: a complete RS-232 communications package, user-definable keys, 'Date-stamped' files, Job Control Language, Print Spooler, Print formatter, keyboard Type-Ahead and much, much more. The disk BASIC supplied with LDOS is designed for fast operation, and includes many features that will appeal to both the experienced programmer and the novice. Single-keystroke commands and a cross reference utility provide for fast program editing and debugging. A fast machine-language sort is included. For any specific questions, or more information, please contact us here at LSI. Order L-10-010 for the Model 1, and L-10-030 for the Model 3, or operation on the Model 4 or 4P in the Model 3 mode. Model 3 LDOS will take advantage of the faster clock speed of the Model 4 when running in the Model 3 mode.

LDOS supports single and double density, single and double sided disk drives. All disk drive parameters may be adjusted to optimize performance on almost any given hardware. Both the PERCOM and Radio Shack types of double density adapters are supported on the Model 1. Disk formats are directly interchangeable between versions of LDOS 5.1, so files may be easily transported from one machine to another. The documentation for LDOS is both extensive and complete. The (over) 350 page manual covers almost every phase of daily operation, and comes with complete technical information. Many examples are given for almost all library commands and utilities. All the features of the LDOS system could not possibly be covered in this small space, but some of the highlights are: a complete RS-232 communications package, user-definable keys, 'Date-stamped' files, Job Control Language, Print Spooler, Print formatter, keyboard Type-Ahead and much, much more. The disk BASIC supplied with LDOS is designed for fast operation, and includes many features that will appeal to both the experienced programmer and the novice. Single-keystroke commands and a cross reference utility provide for fast program editing and debugging. A fast machine-language sort is included. For any specific questions, or more information, please contact us here at LSI. Order L-10-010 for the Model 1, and L-10-030 for the Model 3, or operation on the Model 4 or 4P in the Model 3 mode. Model 3 LDOS will take advantage of the faster clock speed of the Model 4 when running in the Model 3 mode.

LDOS supports single and double density, single and double sided disk drives. All disk drive parameters may be adjusted to optimize performance on almost any given hardware. Both the PERCOM and Radio Shack types of double density adapters are supported on the Model 1. Disk formats are directly interchangeable between versions of LDOS 5.1, so files may be easily transported from one machine to another. The documentation for LDOS is both extensive and complete. The (over) 350 page manual covers almost every phase of daily operation, and comes with complete technical information. Many examples are given for almost all library commands and utilities. All the features of the LDOS system could not possibly be covered in this small space, but some of the highlights are: a complete RS-232 communications package, user-definable keys, 'Date-stamped' files, Job Control Language, Print Spooler, Print formatter, keyboard Type-Ahead and much, much more. The disk BASIC supplied with LDOS is designed for fast operation, and includes many features that will appeal to both the experienced programmer and the novice. Single-keystroke commands and a cross reference utility provide for fast program editing and debugging. A fast machine-language sort is included. For any specific questions, or more information, please contact us here at LSI. Order L-10-010 for the Model 1, and L-10-030 for the Model 3, or operation on the Model 4 or 4P in the Model 3 mode. Model 3 LDOS will take advantage of the faster clock speed of the Model 4 when running in the Model 3 mode.
