194 Finally have a working board. davidgb 1225d 23h /System09/trunk/rtl
193 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. Also fixed the 32k addressing davidgb 1226d 03h /System09/trunk/rtl
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 1226d 03h /System09/trunk/rtl
189 Remove unused file. Created by ISE gui. davidgb 1232d 18h /System09/trunk/rtl
188 update options to match what the ISE gui does davidgb 1232d 18h /System09/trunk/rtl
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1232d 23h /System09/trunk/rtl
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1233d 02h /System09/trunk/rtl
185 Reverted back to the single-step version - something was broken davidgb 1233d 04h /System09/trunk/rtl
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1233d 05h /System09/trunk/rtl

177 work on zybo port davidgb 1233d 16h /System09/trunk/rtl
176 Don't delete system09_impact.cmd on 'clean' davidgb 1233d 18h /System09/trunk/rtl
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 1233d 18h /System09/trunk/rtl
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 1233d 21h /System09/trunk/rtl
173 Add another 16k BRAM for 56K total memory davidgb 1235d 17h /System09/trunk/rtl
172 Add 16k RAM davidgb 1235d 17h /System09/trunk/rtl
171 remove old Xess files davidgb 1235d 22h /System09/trunk/rtl
