. The keyboard on my Apple II+ is acting funny. I type characters, and the wrong characters come out. It looks like the decoder is messed up. Do I need a new ROM of some sort, or completely new keyboard circuitry? If anyone has a spare keyboard (not necessarily the keys; all I need is the circuitry, or possible just a new decoder), please contact me. Thanks. -drew arpa: MOORE%MIT-EECS@MIT-MC.ARPA uucp: ...mit-eddie!moore us: Box 121, North Quincy, MA 02171

There are two basically different II+ keyboards - the old original and the so-called "two-piece" keyboard. The latter has all the logic chips on a small second pc board which is attached loosely to the back of the pc board on which the keys are mounted. If you have the old one-piece keyboard, forget it. The decoder chip is long out of production and is no longer available unless you are lucky and find one in somebody's bottom drawer. for a while, Apple was offering a good trade-in deal in which authorized dealers would swap a new keyboard for an old for about $40. this was a couple of years ago, but you might ask some questions and see if you can talk someone into this. The newer keyboard has a more conventional decoder and you might actually be able to buy a replacement chip. Call a couple of apple repair shops, get connected to their head repair person, and ask some questions. I don't think it is a unique apple part, and one of the hardware gurus may know where you can buy it cheaper from a parts distributor. /Dave

It seems to work fine and was $49.95 with 6.00 for shipping/handling.
