>> Chips:
6809, 6821, 6850, 6264, 27128 and 27256.
I was programming these parts as far back as 1979 [Ok I was using eproms, but the 27128/27256 are not that much newer].
I am surprised that these parts are still in production..
That was the main motivation for the move to the 6809, which has much
broader availability than the 6802.
My main question, however, is that since this is
intended (I believe) for
long term use, is this the best hardware to base a design on. What are the
chances of getting spares for these components in 2014?
I believe that this is a problem with virtually *any* component you could
choose. The newer stuff seems to generally have shorter lifespans. I
believe this is an outcome of having more choices -- none of the "newer"
chips (with perhaps some exceptions from Intel) has enough of a following to
be readily available down the road.
At least these old-time components have a following that has kept them
around this long...
I'm curious what everyone thinks of this issue, and what *are* the better
choices?
