I believe the 8044ABM under discussion is NOT a microcontroller; I'm fairly certain is a keyer chip from Curtis Micro Devices. It has been around, is some form or another, since well before the 8051 was around. The 8044ABM is a custom built, CMOS keyer. I think it is MSI, not LSI, too. Curtis sells the chips directly, look in the ham rags (QST, 73) for their address. -- * Dana H.
