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.

201 A copy of XSA-3S1000.ucf and System09_Xess_XSA-3S1000.vhd that have dual serial ports with no handshake. davidgb 1252d 02h /System09
200 Started adding back in video support - VDU8 instantiated and RGBHV bits sent to Pmod JE port. davidgb 1258d 23h /System09
199 Add in full RS-232 handshake for PmodUSBUART. davidgb 1260d 00h /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.

196 Working system boots to SBUG. Uses RS232 Pmod (no handshake) and 57600,8,N,1 (no handshake) hyperterm. davidgb 1266d 23h /System09
195 Switched to using the UART over usb for the console port. davidgb 1267d 00h /System09
194 Finally have a working board. davidgb 1267d 00h /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 1267d 04h /System09
