Is that what's called the 'shrink-dip' package in parts of the
industry? I remember years back having to order some special ZIF
sockets to make use of them with an NEC micro we were using. And
just last week I was looking through the detris from the old
electronics lab at work and noticed a fragment of circuit board
designed expressly for mounting one of those chips. It had been
chopped up, though, by some cretin who used a part of the 0.100"
pad layout for some other purpose. So apparently there are
prototyping boards available to adapt that pin spacing for
breadboarding/hand-wiring purposes. Back at the time when we
were dealing with it, I just epoxied one of the (expensive, large
minimum order) ZIF burnin sockets onto a standard 0.100" spacing
header to make an adapter. Awkward but it worked. Search on
'shrink-dip' which I believe is the term for chips with that
spacing.
And I am trying to stick to DIP packages to keep
it easy to build with OTS
parts. Or I could stick a primative ISA slot on it and plug in
one of my spare IBM Serial Adapters and use the current loop
interface. (naw... heh.)
That reminds me of something I was wondering about. I've got one of those
HD64180's in the DIP package with the pins on 0.050" centers. Does anyone
know of a socket that will let me use this thing on 0.100" center proto
board?
