Re: Does anybody knows what is 3421 Control module (HP #82500B-A24) for HP-41 Message #5 Posted by Christoph Klug on 15 Mar 2004, 5:06 a.m., in response to message #4 by Garth Wilson
Dear HP41 & HP3421 enthusiasts,
Controlling the HP3421 with HP41 needs the EXT-I/O Module or the 3421 DAC module. The last includes some special keyboard assignments - than the HP41 acts as an remote keyboard for the HP3421.
Usigng CLONIX you are able to programm the 3421DAC rom plus some other roms plus your individual user code software application inside an advanced one port solution...
Alternatively to HP3421 you can use me I/O-Board or the IL2000 System, which includes some more fardware features...
Regards from Germany - Christoph Klug
