Since it appears that a real HP-IL + PIL-box is outside my price range I thought I might try the next best thing, and use V41 with Virtual HP-IL. Is there any way to get V41 to communicate through virtual HP-IL to the software here: https://hp.giesselink.com/hpil.htm ? If so, how might I go about configuring the systems?

Thanks!

After some digging, I finally understand the HP-IL concept and Virtual HP-IL makes much more sense. I was able to get it all hooked up and functional. There must be a loop back to the in port on the HP-41. For those new to Virtual HP-IL,
1) ALT + SPACE to get the menu for the ports
2) each ILxxx interface must port must be sequential for instance
Device (OUT PORT NUMBER / IN PORT NUMBER / (if applicable Printer Port))
HP-41 (60001/60000)
ILScope (60002/60001)
ILBlinky (60000/60002/62000)
HP82240B (62000)

|->HP-41-(60001)->ILSCOPE-(60002)->ILBlinky|->(62000)->HP82240B
|-----------------------------------(60000)<-|

Most of us have been there at some point, and then when you once again see it's called the HP-IL Interface LOOP, we casually look around to see if anyone noticed that we hadn't noticed the... well you understand I'm sure.

This diagram is misleading because there are 2 computers in the same loop.
Not that it's impossible if you master the concepts of active and system controllers, but it's not the simplest HP-IL configuration example...

Well, the above one came from HP. Is this one better ? Wink

I also came across a program called PyILPER which has an integrated plotter. which is very neat

And a new one with the PIL-Box ...

Am I the only one who can't see these tiff images in Firefox/W10 ?
Here are links to download them:
HP-IL_Diagram_v6.tiff
HP-IL_Diagram_v8.tiff

Anyway, great diagrams, Sylvain, thanks!

An other interesting HP-IL configuration use case is with the HP82169 HPIL/HPIB interface in translator mode.

Actually, the 82169 translator mode was a model for the development of the PIL-Box: messages passing in both directions, controller on either side. The PIL-Box core was first called "HP-IL to serial translator".

No, I cannot see them in FF either. Must be a Mac thing... Wink

Thanks for posting the images as attachments. Indeed nice images to explain HP-IL, and also emphasize that more than 1 or 2 devices on the loop are supported and work fine, a common misconception

I don't see the tiff images inline on Mac/Firefox, and when I download using the links it pops up a warning dialog about possible security problems and you have to force it to complete the download. Sheesh.

I am seeing the images just fine.

Safari 15.3 and Firefox 97.0.1
Mac OS 21.2.1

That is just Firefox being parental this will happen when you try to download anything that is not coming from a secure ie HTTPS protocol server, it would seem that these days Firefox assumes that if the server is not using a secure protocol it must certainly be a threat to the entire internet. Chrome on Linux does not seem to have any issue with opening those links. You will also have trouble with links that use the old unsecure ftp protocol.

I was not aware of the issue, changed to jpeg.

For some reaseon, the link was set to HTTP instead of HTTPS, changed.
