HP-IL Sniffer - Giuseppe Marullo - 11-08-2003 Hi all,
Just wondering which are the "System requirements" to run a HP-IL sniffer on a second calculator. Thanks in advance,
Giuseppe Marullo
Re: HP-IL Sniffer - Raymond Del Tondo - 11-08-2003 Hi,
I think it would be easier to use an HP-71B as the sniffer, However, since it's a loop, your sender gets back what it submits, so your sniffer could be your first HP-41;-) Regards,
Raymond
Re: HP-IL Sniffer - Giuseppe Marullo - 11-08-2003 Raymond, About the HP-71, maybe is cheaper to get a 75, that has a standard hpil port. I don't remember which is best at hpil stuff between the two.

Re: HP-IL Sniffer - Raymond Del Tondo - 11-08-2003 Hi Giuseppe, for HP-IL functionality beyond the standard protocol maybe Christoph Klug and Jean-Francois Garnier are the persons who may have the answers;-) AFAIK the HP-71 has the most advanced HP-IL implementation ever made. Regards,

Re: HP-IL Sniffer - Giusepe Marullo - 11-08-2003 Raymond,
Actually it seems that a HP-71 is rather expensive compared with a 75. Which could be a reasonable price for both? BTW, I have both devilrom and ext i/o rom, so it is natural to place both on different 41 and have one "sniff" the other' operations. They were not cheap by my standard, better use them.

Re: HP-IL Sniffer - Vassilis Prevelakis - 11-09-2003 Yes you can use a second 41 as a sniffer but you need the I have actually used this combination and its very powerful. Having said that, the 71B is the best IL controller made so using this machine is probably a better idea.

Re: HP-IL Sniffer - Giuseppe Marullo - 11-09-2003 Thanks Vassilis, Re: HP-IL Sniffer running on PC - Christoph Klug - 11-10-2003 Dear HP-IL enthusiasts, remember that it is also possible to use a PC with EMU41 or the new EMU71 plus HP-IL/PC interface card for monitoring the interface loop. Using the PC you get one or two virtual handhelds plus much more advanced features....
Best wishes from Germany - Christoph Klug
Re: HP-IL Sniffer running on PC - Giuseppe Marullo - 11-10-2003 Christoph, I am searching for such a board anyway, but a USB porting of the board would be greatly appreciated. Giuseppe Marullo
Re: HP-IL Sniffer - Mike (Stgt) - 11-10-2003 As Vassilis already sayed, an HP-41 (even an old 41C) with a "Devil"-ROM is sufficient as IL-sniffer. Just start MONITOR on it before you switch on an other controler in the loop. That's all. BTW, what are you going to do? Just currious <G>.
Ciao.....Mike
Re: HP-IL Sniffer - Giuseppe Marullo - 11-10-2003 Hi Mike,
Anyway it started as a cool terminal to be used to setup a minisumo robot on the dojo. I don't want to use a laptop, there are a lot of people around and actually *nobody* knows the 41 around the people I know (within my same age). At first, I will try to drive my robot using a HPIL->RS232 interface, then maybe a home made HPIL->GPIO or a HPIL->RS232, but the smallest possible. Another interesting project would it be using a pic to emulate some rom, I have found an interesting kit that is able to read files from a FAT32 SD card, using a pic. I don't have any software to preserve, so my point of view is VERY different from most, if not all of you. Maybe others would build something very different.
Who knows, I am still missing the CX "basic" manuals...go figure. there is no guarantee that I will go much further than 2 ENTER 2 + stuff.
Re: HP-IL Sniffer - Mike (Stgt) - 11-12-2003 2 ENTER 2 + stuff is "User Language", I suppose you go for MCode <G>
Ciao.....Mike
