Hai..
Thanks, Jan I'm looking that open-source and documentation about miniLA. Thanks. Here's in my country..bought electronics parts expensive that outside..meanwhile we only get salaries 2-3US$ a day...Alas. Other countries followed the tax rules...get cheap prices. here's bribe costums to past the import and get below tax accumulation...in the mass quantities... No place for experimenters.. --------------------------------------------------------- I'm replacing the Xilinx XC with my Cypress CPLD. How's about AS7C33128PFS32A,Is there similiar IC replacement? Best Regards JBJ >You may find that the XILINX CPLD is faster than the Cypress >types.

All of my test instruments from homemade..except Digital multimeter which we all knew can reach by common peoples.
