HP41 Mcode: SELPF arguments - Meindert Kuipers - 01-27-2010 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 - Raymond Del Tondo - 01-27-2010 Hi Meindert, please take a look into the Zenrom manual;-)
IIRC the SELPF argument addresses the peripheral,
The data word LSB indicates the end of the data sequence, HTH

Re: HP41 Mcode: SELPF arguments - PeterP - 01-28-2010 i think one of the most complete list of SELPF is part of the HEPAX manual which can be found on this dvd as well as on TOS I believe. Cheers
