Also a CPLD (maybe a 9536XL) is about as cheap as
a
GAL now ($1.00 or so),
much more capable, and programmable with nothing but
a parallel port (JEDEC
ISP)
Well not just the parallel port I'm sure. Hope
someone posts the url that has plans for that...
Well yes, pretty much just a parallel port:
TDI to DUT
TDO from DUT
TCLK to DUT
TMS to DUR
4 signals, all TTL level, no special timing...
