HP41 Mcode: SELPF arguments Message #1 Posted by Meindert Kuipers on 27 Jan 2010, 12:11 p.m. While working on my disassembler I decided to add some comments to the SELPF instrcution, but I could not find any substantial info about the meaning of the arguments. 9 seems to be the printer, and anything below 9 belongs to HP-IL. Does anyone have more info about this instruction? Thanks, Meindert

Re: HP41 Mcode: SELPF arguments Message #2 Posted by Raymond Del Tondo on 27 Jan 2010, 12:56 p.m., in response to message #1 by Meindert Kuipers Hi Meindert, please take a look into the Zenrom manual;-) IIRC the SELPF argument addresses the peripheral, and may be followed by data word(s) . The data word LSB indicates the end of the data sequence, which means control will be passed back to the mainframe. HTH Raymond
