- Display Media-ID and Geometry info for all SHOW <unit> output when attached
- Use real drive Geometry info for all disk types
- Fix RA80 cylinders copied from RM80
- Fix RZ23 cylinders to reflect disk size
- Return correct cylinder info on MSCP error path
The first ROM included will be defined with names:
BOOT_CODE_SIZE
BOOT_CODE_CHECKSUM
BOOT_CODE_FILENAME
BOOT_CODE_FILEPATH
BOOT_CODE_ARRAY
and BOOT_CODE_URL
That first ROM will also have names:
BOOT_CODE_SIZE_1
BOOT_CODE_CHECKSUM_1
BOOT_CODE_FILENAME_1
BOOT_CODE_FILEPATH_1
BOOT_CODE_ARRAY_1
and BOOT_CODE_URL_1
Subsequent included ROM's will have names
BOOT_CODE_SIZE_n
BOOT_CODE_CHECKSUM_n
BOOT_CODE_FILENAME_n
BOOT_CODE_FILEPATH_n
BOOT_CODE_ARRAY_n
and BOOT_CODE_URL_n
where n is 2 thru the max number of supported ROM includes.
Leverage drive type flag DETAUTO which defers meta data addition to
happen at detach time. This allows pre-existing containers to be attached
to larger drives (with more platters) with autosize disabled and then if
autosizing is subsequently enabled before detaching, will thus add correct
meta data when the unit is detached.
Newly created containers will have meta data added at creation time and
updated to reflect data written beyond the original data in the container.
Note: To avoid potential breakage of existing PDP11 configurations in
the wild, which may expect RP on RHA, TU on RHB and RS on RHC,
RPB is connected to RHD Massbus adapter.
- More robust recovery when Massbus configuration errors occur
- More complete RH{A,B,C,D} help
Peter Allan analyzed the source code for the VAX780 simulator and
came up with a somewhat simple strategy to replicate the RP device
source code and to add another controller on an additional Massbus.
That initial strategy includes: Copying the pdp11_rp.c source module to
pdp11_rpb.c and making almost all global variables static as well as all
internal functions used in the RP device. All but the "DEVICE rp_dev",
that is, which now becomes "DEVICE rpb_dev" with a name of "RPB".
The change process was relatively simple although somewhat tedious and
wouldn't easily lend itself to manage future changes that might happen to
pdp11_rp.c.
The changes in this commit cleanup pdp11_rp.c so that changing it to
pdp11_rpb.c only need to affect 3 lines of code which will simplify
future maintenance of these modules.
In https:://github.com/open-simh/simh PR number 154 nickd4 that 2 argument
floating point instructions were displayed with the wrong argument order.
This change fixes BOTH the instruction display and the input activities for
these floating point instructions.
* VIDEO: Fix bug: vid_ready can be used uninitialized.
* VIDEO: Not all events come with a valid windowID.
* PDP11: Fix NG SET TYPE.
The sense of MATCH_CMD is reversed.
* display: Fix bug in NG display controller.
There should be a separate state for each of the eight displays.
* display: Symbolic constant for number of displays.
Simulators built with DONT_USE_INTERNAL_ROM defined will not have hte
binary of the needed ROM or boot components build into the simulator
binaries. However, they will automatically and transparently fetch the
neeeded ROM or boot code from the web when these binary files aren't
available locally.
- Plan is to avoid "#ifdef DONT_USE_INTERNAL_ROM" in simulator code
and handle builtin or external files in SCP facilities
- Export ROM checksum value and source file path to allow for transparent
dynamic ROM location at run time.
There are a lot of niggling fixes, mostly for incompatibility issues
found by Walter Mueller. Working out the 11/70 behavior is still not
fully done, but it's a lot better than it was, and it passes more of the
11/70 MMU diagnostic.
- Floating point. Now model sensitive in treating MMR1, for 2.11 BSD.
- MMR1 now tracks PC changes on 11/44, 11/45, 11/70, and J11 -(PC) and @-(PC).
- MMR1 is cleared at start of trap sequence on 11/45, 11/70.
- Red stack abort occurs before memory writes on 11/45, 11/70 (no other model has them).
There are 3 variations of RH11:
- 11/70 Massbus adapter AKA RH70.
- All other PDP11 systems had a Massbus adapter known as the RH11.
- Qbus PDP11 systems had a Massbus adapter known as a RH70 emulator.
This commit extends the existing DUP11/DPV11 support to add support for HDLC framing. There
is no requirement to support bit/byte stuffing, so the aim is simply to encapsulate/decapsulate
the datalink frame provided by the host driver.
DDCMP has been regression tested on VMS, RSX and TOPS20, and the HDLC mode was developed
and tested with VAX/VMS DECnet Phase V, only using the HDLC datalink implementation.
In theory this support is sufficient to allow Phase IV/V P.S.I and even VMS/SNA to be used,
but these remain to be demonstrated.
