I could still use a couple more NS MM5740AAE/N keyboard encoders. These are in a 40-pin dip package. They can probably be found in old 1970s keyboards. I'd be interested in buying either just the chip or the whole keyboard if you happen to find one surplus in your parts bin. If you've got one, please contact me for sale/trade info.
