This is the EMDP3 adaptors section of the
EMDP3 project and it is currently a
work in progress.
EMDP3 Adaptors
There is basically one adaptor for each different
kind of deviced package out there.
-
DIP48Z (DIP 64 - ZIF)
-
This is the work horse adaptor for the EMDP3
system. This one can support 40 and 48
pin ZIF (Zero Insertion Force) DIP sockets.
Many people will choose to buy a less expensive
40 pin ZIF socket instead of the more expensive
48 pin ZIF sockets to save money.
-
PLCC84S (PLCC 84 - Socket)
-
Since a good PLCC ZIF socket is quite
expensive, this adaptor board avoids the
problem by using a standard PLCC socket
instead. Since the PLCC socket is not really
rated for as many insertions and removals
as a ZIF socket, the adaptor will wear out
faster. When a socket wears out, the
owner has the option of removing the
current socket and replacing it with
a new one, or simply purchasing a whole
new adaptor. The board has a 7 sockets
on it, one for PLCC20, PLCC28, PLCC32,
PLCC44, PLCC52, PLCC68, and PLCC84.
-
PLCC84Z (PLCC 84 - ZIF)
-
This adaptor uses an expensive zero
insertion force socket for programming
PLCC chips of size 20, 28, 32, 44, 52,
68, and 84. It is unlikely that this
adaptor will ever wear out. It is based
on the Aries 537 "Live Bug" PLQCC adaptor.

-
SOIC44Z (SOIC 44 - ZIF)
-
This adaptor uses SOIC ZIF socket (base
on the Aries 339 ZIF socket.) This
supports SOIC with leads on a .050 inch
pitch.
-
PGA441Z (PGA 441 - ZIF)
-
This an adaptor that uses a 21×21
pin grid array zero insertion force
socket. Smaller chips can be plugged
into the upper left corner. The printed
circuit board for this adaptor must be
multiple layers in order to get access
to all of the pins.
