do you need a plugin to work with +3 dos images?
ZXNet echo conference «zxnet.pc»
Hello, ng_dead
ng_> this plugin will work not only for Spec’s +3DOS disks, but also for
ng_>CPCshnyh
only theoretically, because if I understand correctly, the CPC has a different dos and
most likely a different layout of file/disk information
len> and I would like it to be possible to throw into using the tr-dos plugin
len> +3 and back
is there any format similar to HoBeta for storing ONE file
without losing the title? if not, then the plugin is in serious question...
Hello elf/2
such a thing, of course, is not an essential thing... but useful.
Moreover, as I understand it, this plugin will work not only for Spec disks
+3DOS, but also for CPC ones. So not only spec users will say “thank you”...
Hello, ng_dead
I'm glad you suggested!!!

very very!
and I would like to be able to use the tr-dos plugin to throw at +3 and
back! :v2_clapp; :v2_clapp:; :v2_clapp;
If; will it be possible, then my project will develop, without this it will be
difficult!
Hello, All
We're actually collecting signatures...

If I understood this, I would have done it myself, that’s why I turned to the one who
At least I did it for tr-dos and type. It would be a big deal for me to make such a plugin
feat, I will have to deal with the headlights and tr-dos and +3 dos.
Request! If at first glance it seems impossible, then please don’t
abandon this idea, maybe the info will come up later and everything will be okay. to me
It seems that it should work out and there should be information.
There is a library for the emulator, maybe something can be pulled out of it.
I proposed to Kladov in a personal message, he didn’t respond, I don’t remember, maybe he wanted to offer
didn't offer...
In principle, if he connected this library to the emulator, then it would be possible through the emulsion
could be copied.

on SRS there is really a different DOS, but it was written by the same Locomotive Software office.
the file system of both is cpm compatible. accordingly, among themselves they
compatible.
later...
which is what needed to be proven :) the CPC emulsion perfectly swallows dsk files +3DOS and
shows the disk directory...

I'm waiting for information :) for now and where it is on the disk is not clear. but there's already a bunch
questions:
1. most of the disks on WOS have one or another protection system (SpeedLock,
ThreeInchLoader...). You can't do anything with them at all.
2. As I understand it, 11 bit attributes for a file are supported. what's wrong with them
do?
3. The file can have a header of 128 bytes. Where should he go?
len> There is a library for the emulator
The library allows you to read/write at the sector level. the plugin works for more
high level
ng_> the CPC emulsion perfectly swallows +3DOS dsk files and shows the directory
ng_> disk..
not bad anymore. I really don’t really understand what CPC is :)
In any case, there is not enough information yet.
We need detailed information about the disk structure, i.e. where is the root directory, in which
it contains information about the files, why the files need a 128-byte header, etc.
well, I still can’t imagine how to “transparently” throw files between
trdos and +3dos

As the owner of the UKNC, I also support such an initiative... But in principle I understand

Hello, Error404
Err> Are there such plugins for CP/M?
No they don't exist. There is a slight complication: CP/M does not have an identifier for
which can determine whether the disk belongs to this OS.

I had to write my own utility to work with CP/M (tested on an emulator
Orion) - wcx plugin for TotalCommander / Far. If anyone is interested,

Hello, Alexandr Medvedev
Ale> But this utility does not work with Spectrum CP/M images.
Where can I see what this image looks like?
I remember exactly that, for example, the Pro had the same format as the Corvette (i.e.
and on Orion/Specialist), only without boot-sector. Just burned it to disk from
Pro standard boot and worked. Perhaps the file format itself is not simple
sequential sector-by-sector copy of the entire floppy disk, and with some packaging or
additional information?
Hello, Error404
Err> Where can you see what such an image is like?
As far as I know, Spectrum has 2 versions of CP/M
For ATM look here http://atmturbo.nedopc.com/
For the Pros, right here is an example of a disk.

In fact, boot comes right after the directory, only it has neither a header nor
signatures, that’s the whole difficulty. I can write the plugin myself, but...
It is impossible to uniquely identify the file.

There are different formats, I specifically for the example removed all the headers and left
only the sectors themselves.
I specifically changed the extension to .odi.

Both formats work - I just added a line for Pro to the inishka. :v2_cheer;

I had to change the extension to PRO, because... for ODI I already had the format set up
"Orion without DPB" (similar, but 4 system tracks, while the Pro has 0 system tracks
tracks)

I did it differently for now. Now I first have on each archive (disk image)
analyze the presence of Disk Parameter Block in the boot sector (1 sector
tracks 0). In the Corvette (and in the Orion CP/M cloned from it) DPB has
checksum and checking its presence is not difficult. If DPB is present then
all settings are taken from it. If missing, then DPB is taken from INI in
depending on the file extension of the disk image, then the DPB is calculated from this
the required (and checked against the input) size of the image file. If it matches, it works with
disk image via DPB from INI.
--
In ini, DPB is configured according to the rules of CP/M 2.2. I have already configured the appropriateDPB for Spectrum CP/M format *.TRD (disk image 655360 bytes, i.e.
16 x 256b sectors, double density, 80 tracks, 4k catalog, 2 system tracks, 16k
extents) and for CP/M images from MSX (disk image 368640 bytes, i.e. 9 x 512b
sectors, double density, 40 tracks, (or 1x80 ???) 4k catalog, 2 system tracks,
32k extents). With all the images already configured (ODI, TRD, DSK, and others
- if configured) the plugin works simultaneously without any additional
switching both under TotalCommander and Far (which is not surprising -
it works farwcx:smile; ).;
--
So here it is. I'll look at the description of the formats using your links, but something already
enthusiasm is fading (supporting at least something Spectrum was a matter of principle
:v2_finge; :smile:; ), especially since it seemed to me that *.TRD is a format
quite common - quite a lot of CP/M software is lying around on the Internet
in it, as it turned out.

Plugin and sources if anyone is interested (so far no one has commented except you
:v2_conf2; ); there - on the page (address in the signature) in the "File" section.
Hello, Error404
clear discs for +3 can be counted on one hand, everything else is in its own format,
Each company did it differently
