Reading/Writing TRS-80 Disk Media on an IBM
If you have a 5.25" drive hooked up to your IBM PC, the following programs can be used to read TRS-80 disks into the DMK/DSK format. If you want to read Model 1/3/4 disks and have a Catweasel card, use Tim Mann's CW2DMK utility. If you want to read Model 1/3/4 disks and do not have a Catweasel card, use Matt Read's READDISK utility. If you want to read COCO disks, use Jeff Vavasour's RETRIEVE utility.

Documentation
READDISK transfers files from a TRS-80 Diskette to an IBM .DSK file without special equipment. This version can also read Tandy 1000 disks.

READDISK is an MS-DOS program that will run on an IBM PC compatible computer. Obviously, the PC must have the proper size disk drive. (In other words, to read 5 1/4" TRS-80 disks, your PC must have a 5 1/4" disk drive.) READDISK will not work under Windows NT, Windows 2000, or Windows XP.

Please note that not all PC disk controllers are capable of reading TRS-80 disks. This is a limitation of the disk controller, not READDISK. If you have trouble, try running READDISK on other PC's until you find one that can read your disks. Remember, you only need to read your TRS-80 disks once to convert them to disk images, so be sure to use the "Retry" command heavily.

(NOT A TYPO)		 Jeff Vavasour Home Site
The TRS-80 Model 4 Emulator's virtual disk utilities have been provided free for download in order to allow you to determine whether your PC has the features necessary to read and write TRS-80 floppies directly. The emulator can either access your TRS-80 floppies directly in its floppy drive, or as images copied to your hard drive. Either way, you need to be able to determine whether the PC hardware can read the floppies.

DOS WAV to CAS Utility v2.0.0.2 (Bug Fix 2)
 February 4, 2008 Knut Roll-Lund Home Site
Wav2cas is a Windows program, run in a DOS window (or you can use drag'n'drop, dropping the wav file onto the wav2cas desktop shortcut icon), which takes an uncompressed Windows wav file (made from a Model I Level II (500 Baud), Model I Level 1 (250 baud), or Model III (1500 Baud) cassette tapes) and generates a cas file for use by TRS-80 emulators. Silent bits doesn't matter, so an entire tape can be converted (but header synchronization is only done once, so this is risky).

DOS High/Low Cassette Converter None April 28, 2005 Knut Roll-Lund Home Site
Highlow is a small utility for converting CAS files between Highspeed (1500 Baud) and Lowspeed (500 Baud). Since 1500 Baud includes a startbit, making the file contents unreadbale, it is useful for viewing the contents of a highspeed CAS file after a wav2cas_h conversion, to do a preliminary check for success or to get the name from a system tape. It can convert both ways and does so automatically. It can't handle multiple files in a CAS file so only single content CAS files may be used, and it must detect the header so it can't deal with fragments.

DOS ACAS CAS Analyzer None Knut Roll-Lund Home Site
ACAS is another small utility, this time for checking the cas files. Actually it is a beta as it will be incorporated in another program but I decided that I would release this standalone version anyway. As it is now it will scan through a cas file and find out what it can about it and output what it thinks to a txt file with the same path and name.
ACAS will read model I and III type of CAS files, it will attempt to decode the first program it finds, if there are data after what it perceives as a program these will be listed as hexcodes. For highspeed it will check that the startbit is ok. It does SYSTEM tapes, reporting the blocks, does the checksum, looks for gaps. It does BASIC, listing the program detokenizing all except what is in quotes or behind a REM, checks the embedded addresses, reports any codes in quotes or behind REM.
