This avoids a potential invalid pointer dereference when formatting
the return value from sim_instr() if it is < SCPE_BASE but greater
than the previously defined static array size.sizeof
Update simh.doc to reflect this generic change.
This implements the principle of "least surprise", in that users won't
normally expect to start overwriting an existing file on these devices.
Real hardware didn't behave that way. A new (empty) file can always
be created with the -N switch on the ATTACH.

Removed DEV_NET and fixed DEV_type on various devices.
Support for 64 lines on KL10 FE by default.
Fixed support for 32 lines on DC10.
Support for TYPE 340 Display undocumented functions.
- Make all PDP11, VAX RP and RQ devices autosizing behave similarly
- Generalize the attach help to be specific to the device/system being
attached
- Remove the sim_disk_pdp10_* calls which weren't correct or needed
since sim_disk_attach_ex provides sector size which is used correctly
The sim_disk_pdp10_... API's specifically provide 1024 byte sector
interfaces for 64bit data.
Customize the attach help output to be more appropriate for the devices
in the running simulator and the device who's help is being displayed.
This allows the underlying disk container formats that that sim_disk supports
(VHD, SIMH or RAW) to be accessed from the PDP10 KS10 simulator, and later
on to Rich Cornwell's PDP10-KA, PDP10-KI, and PDP10-KL simulators.
Although these devices interpret a -A switch at attach time, they are not
sequential output devices and thus don't have an ambiguous interpretation
of the switch.
Incorrectly mentioned in #821
The -A attach time switch implicitly means to open files in append
mode.
Some devices used -A to indicate ASCII data or AUTOSIZE of disk or
fixed size tapes - DECtape. These devices are either read only devices
(Paper tape readers or card readers), so explicit forcing of the attach
to be -R avoids unexpected positioning errors. The random access
Disk and fixed sized tapes buffer the container contents in memory
so append mode isn't relevant, but care must be taken to assure that
the buffer reading starts at the beginning of the file without regard
to the explicit open mode.
As reported in #821
Added BASE option to auxcpu to move memory region.
Fix errors in Card Reader/Card Punch translation and operation.
Fixed problems with ITS quantum timer.
Added support for System Concepts DC10 disk controller (Lars).
Fixed errors in Line Printer control codes.
Added support for Lines per page to LP10.
Fixed issues with 7 track tapes on TM10.
Updated user guides
This will not change much, but it may be useful for sane idling depending
on the way the running OS actually uses the interval timer for clock ticks.
Some discussion about this in #713
Avoid the common situation on with this simulator whereby the programmatic
interval timer is being used for intervals which change often. The internal
calibrated timing routines depend on consistent rate for the calibrated device.
As discussed in #699
