In this page you can find the images of all eproms used in the computer, the images of system disks and other floppy disks containing programs made by me, and also the images of various tapes.
Floppy disk images files with .DMK extension were created by reading floppies with a normal PC with the Catweasel MK4 interface (actually discontinued and almost impossible to find), using the program cw2dmk.exe by Tim Mann, used usually to read Tandy TRS-80 floppies (infact NE-DOS file system is compatible with NEWDOS file system).
At the moment there no other methods to recreate these floppies starting from images without using this interface card. The reason is that the directory track contains sectors ID there aren't recognizable by floppy disk controller used in a standard PC.
To recreate floppies using the Catweasel MK4 interface you need to download the "Catweasel Floppy Read/Write Tools" by Tim Mann. His web site is http://www.tim-mann.org/trs80.html, while the latest release tools can be downloaded from the address:
https://github.com/qbarnes/cw2dmk/releases/download/v4.10.1/cw2dmk-4.10.1-msdos.tar.gz
or you can download it here.
If needed, an older but functional version can be downloaded here.
Then you need to use this command:
dmk2cw -d1 -s1 -v1 -m1 -k2 IMAGE_FILENAME.DMK
The parameters -d1, -m1 and -k2 can vary depending on the drive you own.
If you are saving on a 3"1/2 floppy the parameters are: -m1 -k2
If you are saving on a 5"1/4 floppy in a 360K drive the parameters are: -m1 -k2
If you are saving on a 5"1/4 floppy in a 1.2M drive the parameters are: -m2 -k1
The "-d" parameter is used to set the drive to use. Write "-d1" if you are saving on the A: drive or write "-d0" if you are saving on the B: drive.
3"1/2 floppies need to be necessarily DD. If you are using a HD drive you can use a HD floppy but you must close the right floppy hole with some insulating tape, so that the drive thinks it's DD.
Floppy images with .IMD extension were created by the program "ImageDisk", that you can download here. NE-DOS floppy disks .IMD images (NE-DOS images ONLY) have translated datamarks, so they need to be converted as shown below.
The only manual parameters to be set when using ImageDisk are drive to be used (A: or B:) and "Double step", that need to be placed "OFF".
If you use 3"1/2 floppy disks they need to be DD. Is you use a HD drive you can use HD floppy disks by closing their right hole by way of plastic tape, so that the drive see them as they are DD.
Floppy disk format is explained in the add-on and researches section.
Finally I found a manner to distribute NE-DOS format floppy images, so that they can be written using a normal PC.
The workaround is to use Z80NE to convert directory track data address mark (track 17) that PCs are not able to read by changing them to data address mark that PCs can read, so that it's possibile to subsequently read and write disks using a normal PC with ImageDisk program.
Conversion is done using Z80 computer and a proper assembler program written by me. This program is stored into a ImageDisk image that can be written to a floppy using a PC. This is an autoboot floppy on Z80 and, thanks to the assembler program, its data address marks don't need to be converted.
WARNING: boot disks that contain this program need "1390" or "2390" eproms (that are the eproms that boot NE-DOS version 1.5 or G.1.0 respectively). They DON'T work with "390" or SONE "683" eproms. This method has to be used only with NE-DOS formatted floppy disks: it doesn't work for SONE or other disk formats.
So, follow this method to recreate NE-DOS format floppy disks starting from .IMD images downloadable from this site:
At this time you can reset the computer and use the converted floppy normally.
In case you have disks and you want to make images then proceed exactly in reverse, so:
Floppy disks with converted data address marks (like images that are downloaded from this site and that are written on a floppy disk with ImageDisk) can be used directly on a PC running David Keil TRS-80 model 1 emulator and its F350_720.dsk driver, after booting it on NewDos 2.1.
Z80 converted floppy disks can't be booted on TRS-80, but they can be read/written by the emulator putting them into the physical PC disk drive: the emulator needs to boot to NewDos 2.1, and you need to put the image of a particular floppy named F350_720.dsk in an emulator virtual disk (this floppy image can be found in the emulator distribution between its utilities). This floppy image has the purpose to tell the emulator to use the physical drive where you will put our converted Z80 floppy disk. This way, when accessing the virtual drive, the emulator will write and read on the physical PC drive and so on our Z80 floppy disk.
I didn't check if converted floppy work on a real TRS-80 yet, but I surely will try in future.
You can download David Keil emulator version 6.21 here also. Into the .zip file there are the needed utilities and NewDos 2.1.
Instead, the audio tapes images were created by reading the original tape with an audio card on a PC and by saving the file in .wav format.
Then the saved audio file has been processed by a program made by me that analyzed its content, corrected imperfections, and converted the audio signal to bytes (so the file originally saved on the tape was recreated). Then this file was read and a new .wav file was generated, with a perfect wave shape because it has been digitally created.
So the tape images you will find here are all with a perfect audio signal and without any errors. I suggest to download and write them on a CD that can be read with a normal CD player connected to the computer tape interface, or connect the PC audio output to the tape interface and use the PC as player with Windows Media Player or WinAmp (warning: if you want to convert the images to MP3 format you need to use a high quality conversion, because MP3 format is "lossy" and it's hard to make them to work properly).
In every .zip file there are three audio files of the same program, recorded at a speed of 300, 600 and 1200 baud. Use the file you need depending on the speed you have setup and calibrated on the tape interface.
The files containing eprom images can be used directly with any eprom programmer to recreate the original eprom. They are in raw binary format, without headers.
In any case, if you need some floppies, tapes or eproms and you aren't able to recreate them starting from images, e-mail me and I'll try to please you and send them to you at the only shipping costs.

These programs manuals are in the magazine number 82/83 (PROGRAMMI NUOVI PER MICRO Z80) and in the manual ISTRUZIONI E COMANDI PER BASIC ASSEMBLER PIU' GRAFICA. This version has been recovered by undeleting some files that were on the original NE-DOS version G.1.0 floppy. Probably, Nuova Elettronica tecnicians saved that files on the master floppy to be distributed, but they deleted them because that files weren't part of the distribution (infact editor assembler/disassembler was sold separately). Anyway, due to the fact that they are recovered files, I cannot guarantee that they are the official version and not a test version instead. However, from the tests I made, they work perfectly. From the NE-DOS version G.1.0 original floppy I was able to undelete and recover the following programs, that I saved on this floppy: Editor assembler, Disassembler, Super Debug, Disk Print and LmOffset. The Super Debug has been announced on the magazine, but it was never released. It's clear that it's a preliminar version, because it's clearly a bad preliminar translation in italian of an english program, probably SuperZap that was made for Tandy TRS-80. The Disk Print is a program never named on the magazine, that dumps floppy contents on video or printer. Then the LmOffset program, also never named on the magazine, it's the same program that can be found on the Tandy TRS-80 |

Following floppy disks are part of Constantinos Haritakis disk library (thanks to Pino Giaquinto that gave them to me for dumping).
Unfortunately some floppy disks aren't completely readable, and some files could be corrupted. In the following table there are disks errors if any.
Almost all these floppy disks where used on both sides by way of a patch made on LX.390 floppy disk interface that let it address the second side of drive 1 as it would be drive 2: the computer saw both sides as two different physical disks with address 1 for side A, and 2 for side B.
To maintain compatibility with original Z80 NE drives and to avoid making the patch on floppy disk interface to read second side, all disks have been converted from double side to single side. So, for example, file name CH06A.IMD mean it's the first side of disk 6, and CH06B.IMD mean it's the second side of disk 6. These disk images must be normally written on different single side physical disks.
