187 Partially works. Garbage on the ACIA due to baud clock problems. davidgb 1405d 17h /
186 Somewhat functional boot to SBUG. ACIA freq is wrong but sometimes works if hyperterm set to 115kBps davidgb 1405d 21h /
185 Reverted back to the single-step version - something was broken davidgb 1405d 22h /
184 update files to correctly produce flex9ram.vhd davidgb 1405d 22h /
183 update file extensions davidgb 1405d 22h /
182 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1405d 22h /
181 Add a copy of the derived ROM contents so that you can go directly to ISE GUI without having to 'make roms' davidgb 1405d 22h /
180 removed xdc file since ISE 14.7 does not support XDC davidgb 1405d 23h /
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 1405d 23h /

177 work on zybo port davidgb 1406d 11h /

System boots but the baud clock must be wrong - get garbage on hyperterm.		 davidgb 1406d 12h /
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 1406d 16h /
173 Add another 16k BRAM for 56K total memory davidgb 1408d 11h /
172 Add 16k RAM davidgb 1408d 11h /

170 More debugging. Can now see cpu_addr incrementing correctly.
Added 32k BRAM 0000-7FFF.		 davidgb 1408d 17h /
169 Fixed clock connection and reset button polarity. Debug LED counting and cpu_clk now indicates some activity. davidgb 1408d 22h /
