[Simh] Modifying SimH kit

[Patrick Renouvel]

Hi All,

I received a precious help from Matt (thanks a lot Matt)

Unfortunately I'm really bad with make, compiling and linking kits

Could someone help me in this way ?

Thanks a lot by advance .

Kind regards.

Patrick.

This configuration works fine, I've used it several times before. Under 
Linux no changes should be needed to the Simh code but under Windows you 
will need to change sim_fio.c as follows:

#include "sim_defs.h"

change to:

#include <share.h>
#include "sim_defs.h"

---

return fopen64 (file, mode);
#else
return fopen (file, mode);
#endif

change to:

return fopen64 (file, mode);
#else
return _fsopen (file, mode, _SH_DENYNO);
#endif

This will prevent exclusive locking on the image file. I don't know if 
any changes are needed to the other supported platforms.

I also did a demo last year with storageworks disks on a shared SCSI bus 
between a PC and a VAX 4000-200 (with a CMD MSCP/SCSI card). The system 
disk was a host based shadow set made up from two of the SCSI disks, 
maintained by Simh and the real VAX.
