exorsim does not recognise double sided disk images

[crestr1]

It appears to log them in on mdos startup as only having 2002 sectors not 4004 sectors.

mdos disks have 77 tracks of 26 128 byte sectors on each side

As a warning to users:

it appears that on shutdown auto-save DS images can wind up as SS, loosing half their size if you have used/altered them under mdos during that exorsim session.

Have not yet had time to look at the disk image cluster allocation and lockout tables to see how they are treated when you attempt to read and write files on a DS disk image.

The mdos "DUMP" command "S 1,2" shows the two CAT sectors data

Can you show what it says when you start exorsim with a double-sided disk? For single-sided disks, it prints a line like this: 'mdos.dsk' opened for drive 0 (single sided)

mdos startup and dump DS disk drive 1 sects 1,2

attaching two disk images last data byte is at 0x7D1FF Images.zip the test image was to make formatted but uninitialized disks from

Ah well this EXORwin program is not mine!

When I use exorsim ("exor" command in this repository), I get this:

./exor user1.dsk Load facts file 'facts' Couldn't load 'facts' 'exbug.bin' loaded. 'user1.dsk' opened for drive 0 (double sided) <---- Recognized as double sided Hit Ctrl-C for simulator command line. Starting simulation...

CONT/LOAD/VERF

But also it does not like the CMI Read Test Image, the file is the wrong size:

./exor CMI\ Read\ Test\ Image.img Load facts file 'facts' Couldn't load 'facts' 'exbug.bin' loaded. 'CMI Read Test Image.img' is not a valid disk: it's size must be 512512 or 256256

I think double sided is working with my exorsim program:

 ./exor mdos.dsk user1.dsk 
Load facts file 'facts'
Couldn't load 'facts'
'exbug.bin' loaded.
'mdos.dsk' opened for drive 0 (single sided)
'user1.dsk' opened for drive 1 (double sided)

Hit Ctrl-C for simulator command line.  Starting simulation...

looks like there is a use-by-date problem here: This points to the jhallen source code. The exe file we are using was from their link to the jhallen sandbox windows version.

I downloaded this quite a while ago and it was taken up by our Motorola 68xxx community because it gave us source code compatibility with all the old stuff we needed to move to more modern computers and media for archive and other purposes.

We have even tried running the Motorola PC cross assembler family in DOSBOX but they are not fully source code and directive compatible with the Genuine Exorciser resident software RASMs and linkers

Is a better working version of this one i sent the screen-shot of what we would get if we ran the latest makefile ?

I'm sure a new w10 one in the sandbox would be greatly appreciated, Not all the user community can do the make

Hi Joe

thanks for your very valuable work in making this software

attached is the copy of exorsim/exorwin we are using, we got this years ago.

it has served our community well until we started to get double sided disk images and it started corrupting them

the CMI read test image can be cut down to the size needed using a hex dump program and it provides both SS and DS images of formatted but uninitialised disks.

you get a DS disk by chopping it off at 0x7D200 just after the end indication text in the image.

the extra was put on to allow HXD software to create floppy disk data stream images that can be fed to floppy disk drive interfaces as floppy disk output data streams

cheers, Tony

EXORwin is from here: http://www.exorciser.net/excorciser3_en.htm It's a Windows GUI program. I see he says no more support available for it, and unfortunately, not source code is available.

exorsim is my code, is open source, and is here: https://github.com/jhallen/exorsim But it's a command line program, not GUI. I've used it in Windows under Cygwin and in Linux.

Hi Joe,

finally got around to cygwin tests of exorsim would appreciate some pointers here

attached make of exorsim I think shows a linking error that prevents getting an exe file

it seems that the rest seems to produce .exe files ok

I've checked in a fix for this, all header file issues.

Please "git pull" and try compiling again.

Sorry, I mean "git pull".
