209 Started adding in keyboard (not tested).
Added in green-only VGA output thru Pmod port to PmodVGA J2 port.
Started working on HDMI output		 davidgb 1106d 23h /System09/
208 swapped 32k and 16k ram to use block_spram. davidgb 1151d 00h /System09/
207 Updated design to pick up vdu8_spram (which uses parameterized ram for video memory instead of hard macros) davidgb 1151d 01h /System09/
206 Update comment/cleanup davidgb 1151d 01h /System09/
205 A new version of VDU8 that uses the parameterized xilinx ram "block_spram" for the video memory. davidgb 1151d 01h /System09/
204 patched up ram for zybo use davidgb 1151d 01h /System09/
203 Added a parameterized ram model. davidgb 1151d 01h /System09/
202 Updated Zybo design to reintroduce VDU8 driving the PmodVGA on pmod connectors JC+JD.
This version also uses PmodUSBUART on JE. To use PmodRS232 you must edit the .ucf file and select the appropriate pin LOCs.		 davidgb 1151d 02h /System09/
201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1157d 21h /System09/
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1164d 18h /System09/
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1165d 19h /System09/
198 Update UCF file to select Pmod pinout compatible with the PmodUSBUART.
To use, make sure PmodUSBUART has JP1 as "LCL". Connect the usb to the uart and open the terminal program. Test the transmission via the LED on the Pmod. Then (carefully) plug into Pmod port on Zybo.		 davidgb 1165d 21h /System09/
197 Updates from John Kent:
-- 4.5 John Kent 2012-02-04 Re-arranged Rx & Tx Baud clock edge detect.
-- 4.6 John Kent 3021-01-30 Double sample RxC, TxC, and RxD with cpu_clk
-- for 125MHz Clock on Zybo Z7 board.		 davidgb 1172d 18h /System09/
196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1172d 18h /System09/
195 Switched to using the UART over usb for the console port. davidgb 1172d 19h /System09/
194 Finally have a working board. davidgb 1172d 19h /System09/
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 1172d 23h /System09/
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 23h /System09/
191 check in file so that you do not need to generate it when running ISE in gui davidgb 1173d 20h /System09/
190 check in file so that you do not need to generate it when running ISE in gui davidgb 1173d 20h /System09/
