Thanks to everyone.. I called MFJ and they didn't have a replacement
chip... This is for a 422 keyer I bought off E-Bay Of course, it was
suppose to be working .. But it had a blown keyer chip.. It's on it's way
back for a refund.. shrug

Yeah, I used the K-10 chip in a QRP rig a while ago. They have a nice
product and it's small.. Actually I have the battery version of the K-12,
(using a watch battery) mounted in a mouse that I use for QRP.. Talk about
cool and easy to do!...

Well MFJ did not tell you the whole story (typical of them BTW)

They do have the Curtis 8045ABM (28-pin chip) that can be adopted to the
product. Some older 8044 chips (14-pin) do appear from time to time.
