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 1172d 10h /
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1173d 07h /

187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1179d 07h /
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1179d 10h /
185 Reverted back to the single-step version - something was broken davidgb 1179d 11h /
184 update files to correctly produce flex9ram.vhd davidgb 1179d 11h /

180 removed xdc file since ISE 14.7 does not support XDC davidgb 1179d 12h /
179 Zybo port done to the same point as the Atlys port. The hardware appears to work but the ACIA is not communicating properly. davidgb 1179d 12h /

System boots but the baud clock must be wrong - get garbage on hyperterm.		 davidgb 1180d 01h /
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 1180d 05h /
