Is there anyone on this list who is into z80 vhdl and crypto?

I am looking at porting pgp onto a z80 with some hardware
acelleration for the crypto.

I am good with z80 asm, good with logic, an amature with vhdl and
while I understand crypto I am not a guru. Anyone able to help?

Also I have some timing issues with zxgate using external rom and ram
for the video, I seem to be grabing the wrong pixel data, values of
pullups or even touching the data bus seems to affect it. Anyone
else had this? I am using 2s300e 3.3v output with 150ohm series and
4.7k pullup to cmos rom/ram at 5v

cya, Andrew...
