+===== Training Sessions =====
+Discussion about the CPLD6502 trainer can be found [[http://forum.6502.org/viewtopic.php?f=10&t=6974|here]]. The sessions were done with [[:builderpages:plasmo:6502:cpld6502:cpld6502r0|rev0]] of CPLD trainer; because of small differences between rev0 and rev1 design, some CPLD design files are updated to work with rev1 design.
