This is what is needed to use the PIL-Box with an HP-41
Code:
HP-41    -> main calculator/computer
82160A   -> HP-IL interface for HP-41, loop controller
PIL-Box  -> HP-IL to/from USB interface
Emulator -> communicate with PIL-Box and emulates several HP-IL peripherals like: tape drive, floppy drive, video, printer, plotter, etc. (see links from previous post)

I would also suggest to look at the HP-IL Compendium

I don't have Kermit capability on my 41 (not directly at least; maybe it could be done) but I do have the FSI164A HPIL-to-RS232 interface converter which is nearly identical to the HP82164A except that the FSI came with two RS-232 channels standard, and optionally up to eight, and optionally battery-powered. I suppose a module could be written to do the Kermit protocol over serial with the __164A. If you have HPIL, you can interface to nearly anything, one way or another. I also have the HP82165A HPIL-to-parallel interface converter, the HP82169A HPIL-to-IEEE488, and the HP92198 HPIL-to-80-column video. My HPIL module has the Extended I/O module built in, so it's a double module.

I'm only seeing the USB stick. USB is much, much more complicated than SD card. To further simplify things, SD card has an SPI mode.

then you're not looking right: go to minute 3:40, it even says on the screen message " Use a micro SD Card for data transfers"

Ok, my mistake. I took the first post too literally and went to 3:50, but missed the seconds between 3:40 and 3:50 where it shows him inserting the microSD card.

RE: Some questions on HP-41
Hi all.

That topic is almost 11 years old... ;-)

https://www.hpmuseum.org/cgi-sys/cgiwrap...ead=142210

Feasible, but not practical IMHO... ;-/

Cheers!

Well, IMHO not because it's been considered before and not implemented that means it has no value... on the contrary, perhaps it's so due to its complexity or difficulty and not on the grounds of its usefulness.

So I read in that thread the Meindert was suggesting to show you his prototype , did that ever happen? The functionallity shown on that video is absolutely amazing, read and write, RAW file import, etc...

Cheers,
ÁM

RE: Some questions on HP-41
I actually did make some attempts to revive the project, and today I would do it differently. An SD card in not more complex than USB, given the fact that the microcontroller has libraries for both. A few years back I actually bought a new prototyping board based on a totally different FPGA combined with an ARM processor, with all open source tools, even for the FPGA. A busy job and other priorities made me put this on the shelf, but I will not throw it away, maybe I will do another attempt ...

Regards, Meindert

Yes, yes, yes.... what can we do to sway you to do it?? ;-)
