Subject: Re: What would it take...
that's all relevant of course, if it's a big
production house, producing thousand or millions
of
boards. But the outifits that make these
retro-fits
(LOL LOL no pun intended) are done in a garage
more
then likely. So that being said, just use
individual
ic's. Or perhaps it's alot about
protecting their
investment. But I would also have to say a
considerable amount of development time goes into
designing something that way.
Why doesn't someone just draw up PLANS to build
this
stuff, and sell that? I'd buy it for sure
(well,
if it
was for something groovy I owned...).
Well even if you only make 50, a GAL may save a lot
of after the fact PCB
editing with an X-acto knife... 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...
