194 Finally have a working board. davidgb 1227d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
192 Fixed part of the ACIA problem - the polarity of the NMI was wrong. Now get clean output but input to the ACIA is not working. davidgb 1228d 00h /System09/trunk/rtl/System09_Digilent_Atlys/
189 Remove unused file. Created by ISE gui. davidgb 1234d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
188 update options to match what the ISE gui does davidgb 1234d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1235d 00h /System09/trunk/rtl/System09_Digilent_Atlys/
185 Reverted back to the single-step version - something was broken davidgb 1235d 01h /System09/trunk/rtl/System09_Digilent_Atlys/
176 Don't delete system09_impact.cmd on 'clean' davidgb 1235d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
175 Corrected RS-232 pin connections. Cleaned up code. Removed debug code.
System boots but the baud clock must be wrong - get garbage on hyperterm.
davidgb 1235d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
174 Added button debounce. Single-step button. multiplex LED to show nibbles of addr and data for debug. Confirmed that CPU is reading from sys09swt.vhd SBug ROM correctly. Still need to debug ACIA output. davidgb 1235d 19h /System09/trunk/rtl/System09_Digilent_Atlys/
173 Add another 16k BRAM for 56K total memory davidgb 1237d 14h /System09/trunk/rtl/System09_Digilent_Atlys/
171 remove old Xess files davidgb 1237d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.
davidgb 1237d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 1238d 01h /System09/trunk/rtl/System09_Digilent_Atlys/
168 Added more pinloc info. Switched RS-232 to use PMOD connector for more h/w debug visibility. davidgb 1238d 01h /System09/trunk/rtl/System09_Digilent_Atlys/
163 more directory cleanup davidgb 1238d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
162 stripped down to most basic system (no vdu, keyboard, sdram, ide, etc). davidgb 1238d 15h /System09/trunk/rtl/System09_Digilent_Atlys/
161 more work on makefile for atlys davidgb 1238d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
160 impact command file for atlys davidgb 1238d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
159 remove Xess tool references. davidgb 1238d 20h /System09/trunk/rtl/System09_Digilent_Atlys/
