[Simh] Modifying SimH kit

[Jason Stevens]

On windows I presume, what part of SIMH? the MicroVAX? 11/780? (I'm assuming
VAX because of what was mentioned way below..)
 
I can whip up something, the patch looks trivial but I'd need to know which
thing you want and if you need networking....

Hi Sergio,

I just wanted to change the c sim_fio.c file as Matt told me to do, but
unfortunately I don't know how to rebuild the kit :-(

Hope I'm more clear :-)))

Thanks for your answer anyway.

Patrick.

Pardon me, Patrick, but reading your first message I am not sure about your
problem with SIMH. 


Regards.

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.
