As previously noted, these use 5V XC9636 Xilinx CPLDs, no current 
limiting resistors or voltage shifters.  The unit should be easily able 
to sink as much current as the C64 PLA.  As noted, I tweaked the 
equations to create similar delays, but they could be further tweaked if 
needed.  I don't have the problematic mobo version that needs the delay 
on the RAS or CAS line (have to go search for the number again), but for 
those who know what I am talking about, it'd be nice to test on that 
board version.

Free to a few folks who are willing to abuse them.

Email me off list with an address.  If someone has a scope and wants to 
make some comparison plots, even better.
