191 check in file so that you do not need to generate it when running ISE in gui davidgb 1215d 10h /System09/

189 Remove unused file. Created by ISE gui. davidgb 1221d 04h /System09/
188 update options to match what the ISE gui does davidgb 1221d 05h /System09/
187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1221d 10h /System09/
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1221d 13h /System09/
185 Reverted back to the single-step version - something was broken davidgb 1221d 14h /System09/
184 update files to correctly produce flex9ram.vhd davidgb 1221d 14h /System09/
183 update file extensions davidgb 1221d 14h /System09/
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1221d 14h /System09/

180 removed xdc file since ISE 14.7 does not support XDC davidgb 1221d 15h /System09/
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 1221d 15h /System09/
178 work on constraints file davidgb 1222d 03h /System09/
177 work on zybo port davidgb 1222d 03h /System09/

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 1222d 04h /System09/
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 1222d 08h /System09/
173 Add another 16k BRAM for 56K total memory davidgb 1224d 03h /System09/
