- trunk (2015-05-14: svn rev 30(oc) 681(wfjm); untagged w11a_V0.65)  +++++++++

  - Preface

    - With small RK05 or RL02 sized disks only quite reduced OS setups could

      be booted, full featured systems were beyond reach. Now finally large

      disks are available, with a RH70 + RP/RM disk controller emulation. It

      supports up to four disks and allows now to run full featured 211bsd

      or rsx-11mplus systems.

    - to track down issues with ibus devices a 'ibus monitor' was added, it can

      record in the default setup up to 511 ibus transactions. An address filter

      allows to select accesses of one device. The ibd_ibmon tcl package

      contains the appropriate support scripts.

    - several cleanups

      - factor out common blocks on sys_w11a_* systems: the core+rbus+cache

        logic of single cpu systems now contained in pdp11_sys70, and the

        human I/O for digilent boards now in pdp11_hio70.

      - cpu start/stop logic cleanup: new command set with simple commands.

        Add also a new suspend/resume mechanism, which allows to hold the cpu

        without leaving the 'run state'. While suspended all timers are frozen.

        Very helpful when debugging, will be the basis for a hardware break

        point logic in a later release.

      - xon/xoff consolidation: escaping now done in cdata2byte/byte2cdata in

        FPGA and in RlinkPacketBufSnd/RlinkPacketBufRcv in backend. The extra

        escaping level in serport_xonrx/serport_xontx isn't used anymore, the

        special code in RlinkPortTerm has been removed. This allows to use

        xon/xoff flow control also in simulation links via RlinkPortFifo.

      - status check cleanup: it is very helpful to have a default status check

        and an easy way to modify it cases where some error flags are expected

        (e.g. on device polls). In the old logic status and data checks were

        done via RlinkCommandExpect. The new logic reflects that status checks

        are the normal case, and store the status check pattern in RlinkCommand.

        The meaning of expect masks for status and data is inverted, now a '1'

        means that the bit is checked (before it meant the bit is ignored).

        The default status check pattern is still in RlinkContext, but will be

        copied to RlinkCommand when the list is processed. RlinkCommandExpect

        handles now only data checks.

    - and bug fixes

      - rk11 cleanup: since the first days 211bsd autoconfig printed

           rk ? csr 177400 vector 220 didn't interrupt

        for boots from a RK11 it didn't have consequences, but when booted from

        a RL,RP, or RM disk this prevents that the RK11 disks are configured.

        Was caused by a missing interrupt after device reset. Now fixed.

  - Known issues

    - all issues: see README_known_issues.txt

    - resolved issues: -- none --

    - new issues:

      - V0.65-1: ti_rri sometimes crashes in normal rundown (exit or ^D) when

          a cuff: type rlink is active. One gets

            terminate called after throwing an instance of 'Retro::Rexception'

              what():  RlinkPortCuff::Cleanup(): driver thread failed to stop

          doesn't affect normal operation, will be fixed in upcoming release.

      - V0.65-2: some exotic RH70/RP/RM features and conditions not implemented

         - last block transfered flag (in DS)

         - CS2.BAI currently ignored and not handled

         - read or write 'with header' gives currently ILF

         All this isn't used by any OS, so in practice not relevant.
