TomPhobos suggested the HxC in the Enterprise forum.
When I view it then see no Enterprise Host control tool! Outrageous!
To change this situation I ordered one for can I develop control sw. It is arrived yesterday.
I started testing
Some words about Enterprise disk formats:
Disk format is a MS-DOS compatible FAT12 standard, 40/80 tracks, SS/DS, 8,9 sectors/track. Original EXDOS ROM also handle 10 sector/track disks, but it is soon modified for can handle 11 sectors. Any extra tracks can be used, most common disk format are 840K. With NEC FD1035 drive can be used up to 90 tracks, I have many disks with 990K format.
For the track numbers the ROM limit are 254.
Now I tested 8/9/10/11 sectors format, also with extra tracks, all working!
The 2.50MB DSDD FAT12 from the HxC sw are also working!
Currently two problems found:
For the 40 tracks disk images the double stepping not emulated. It is looks a 80 tracks disk with the first 40 tracks used. For simple load/save this is not problem, but with some programs which directly acces the disk will be a problem, because the drive detected as 80 tracks drive and a disk as 40 tracks disk then double stepping will be used.
Write Track not working, it is totally skiped, sector data bytes not changed!
Because this, formating the emulated disk stopped with verify error. It is can be done without verify or with program which not check sector data only the Data Error flag of WD.
During the formating mystic WEOE displayed on the LCD, I not found in the user manual what is this...
For example the ep128emu (Enterprise emulator program for PC) at this situation detect the sector data bytes in the track writing data stream and write to the proper sectors in the disk image. It is possible implement least this method to the HxC?
I think this man also found same problem: http://torlus.com/floppy/forum/viewtopic.php?f=2&t=447
