33 - major release w11a_V0.70 (tagged) wfjm 3292d 10h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
30 - added RH70/RP/RM big disk support
- many cleanups		 wfjm 3330d 09h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
29 - added support for Vivado
- added support for Nexys4 and Basys3 boards
- added RL11 disk support
- lots of documentation updated		 wfjm 3396d 06h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
28 - the w11a rbus interface used so far a narrow dynamically adjusted
rbus->ibus window. Replaces with a 4k word window for whole IO page.
- utilize rlink protocol version 4 features in w11a backend
- use attn notifies to dispatch attn handlers
- use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
- use labo and merge csr updates with last block transfer
- this combined reduces the number of round trips by a factor 2 to 3,
and in some cases the throughput accordingly.		 wfjm 3460d 06h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
27 - migrate to rlink protocol version 4
- Goals for rlink v4
- 16 bit addresses (instead of 8 bit)
- more robust encoding, support for error recovery at transport level
- add features to reduce round trips
- improved attention handling
- new 'list abort' command
- For further details see README_Rlink_V4.txt
- use own C++ based tcl shell tclshcpp instead of tclsh		 wfjm 3475d 09h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
22 - interim release w11a_V0.581 (untagged)
- new reference system
- switched from ISE 13.3 to 14.7.
- map/par behaviour changed, unfortunately unfavorably for w11a.
On Nexys3 no timing closure anymore for 80 MHz, only 72 MHz can
be achieved now.
- new man pages (in doc/man/man1/)
- support for Spartan-6 CMTs in PLL and DCM mode		 wfjm 3680d 04h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
13 - interim release w11a_V0.532 (untagged)
- re-organize modules 'human I/O' interface on Digilent boards
- add test designs for 'human I/O' interface for atlys,nexys2, and s3board
- small updates in crc8 and dcm areas
- with one exception all vhdl sources use now numeric_std		 wfjm 4601d 13h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
9 - interim release w11a_V0.52 (untagged)
- migrate to rbus protocol verion 3
- reorganize rbus and rlink modules, many renames		 wfjm 4923d 12h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
8 - interim release w11a_V0.51 (untagged)
- migrate to ibus protocol verion 2
- nexys2 systems now with DCM derived system clock supported
- sys_w11a_n2 now runs with 58 MHz clksys		 wfjm 4959d 02h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
2 initial source upload (no docs yet) wfjm 5100d 07h /w11/tags/w11a_V0.7/rtl/w11a/pdp11_core_rbus.vhd
