HP41 Port to HP-IL Adapter - Mawora - 01-23-2021 09:14 AM Hi there, I do have a HP82143 printer and a HP82153 wand, both with connectors fitting in one of the HP41s' port. I do also own a HP71 with IL module. Now I'm wondering if there's an adapter which enables me to use both units with my HP71. Maybe at least somebody knows, which of the pins in the HP41 connector translates to each of the four HP-IL connections (RX/GND, TX/GND). Somehow hard to believe that I should be the first and only with this kind of need, but I can't find anything anywhere. Any hint will be highly appreciated. Kind regards Matthias[attachment=9042][attachment=9043] RE: HP41 Port to HP-IL Adapter - cruff - 01-23-2021 01:46 PM The HP-41 ports are the HP-41's Nut CPU's bus signals, which do not correspond to the HP-IL signals. Thus you can not use those peripherals as HP-IL devices unless you were to program an HP-41 to act as an interface box between them and an HP-IL module plugged into the HP-41. RE: HP41 Port to HP-IL Adapter - Mawora - 01-23-2021 02:34 PM Hi cruff, thanks for your swift response. Well, this is somewhat disappointing. The HP82143 and the HP82162 look so pretty much the same apart from the connectors, that I hopped even HP was greedy enough not to make too many tailor made solutions and at some point standard interfaces were available (maybe pins at the printers electronics?).

So, a few options less to play around with and fortunately for me it's but playing around with my childhood dreams. RE: HP41 Port to HP-IL Adapter - Gene - 01-24-2021 07:35 PM Don't forget the roughly 3 years between the introduction of the HP-41 and HP-IL. Might not have been as feasible to build it in from the start. Might have delayed the HP-41 project that HP wanted to get introduced as soon as possible. Don't know. Gene |
