The I-PLCC28-32 is a Package adapter that provides a way to program chips in PLCC-28 and PLCC-32 pin packages.

The PLCC ADAPTER will work in any programmer that supports 27256-27080 type chips and supports both 28 pin and 32 pin format by use of a daughter board.

When programming the larger (32 pin) devices you need to remove this daughter board. Please remove it carefully.

When programming the smaller (28 pin) devices such as a 29C256 (the PLCC will still have 32 pins) you need to have the daughter board installed.

Using the PLCC Push Button Adapter:

To insert a chip, grab the socket then press down on the sides, while alining pin one on the chip with the arrow pointing to pin one on the socket, drop the chip in. The chip will drop to the bottom of the socket and when you release the sides the chip will be held in place.

To remove the chip, turn the socket upside down and press on the sides of the socket again.
