Loading ROMs in DM-41L? - toml_12953 - 12-22-2015 01:06 PM

I have a SwissMicros DM-41L and would like to add HP-41 ROMs (such as the printer ROM) is it possible to do? If so how?

TIA

Alas, you cannot. Sorry.

Maybe in a future update?

You mention wanting to add the "Printer ROM". Although it's not currently possible to add a ROM, that could change. Still, this suggestion raises some questions: which printer ROM are you referring to? The 82143 dedicated 41 Printer? That ROM is useful only for that printer itself, which could not be connected. The other possibility is the HP-IL ROM, again which cannot be connected. Curious what are thinking of doing?

The DM-41L offers the same USB socket as the PIL-Box does. It should be possible, at least with some effort, to implement the same HP-IL over USB protocol in order to talk to IL-Per on the PC.

That would be a very great and cool feature!
When dreams come true ...

Well, I suppose anything is possible, but doing this would require not only re-implementing the PIL-Box, but also hacking the 41 HP-IL ROM to work with the peripherals on that new loop. I'll stick with 'cannot be connected'...

Would I love this? Sure, and would buy one in an instant. But I can't imagine there are enough wackos like me for SM to justify such an investment. But as noted above, we can continue dreaming...

With a bit of luck, it is possible to intercept the IL hardware access and translate it to the serial protocol the PIL-Box uses.

Another attempt could be to re-implement the user visible commands natively in the emulator with only a very thin Nut layer.

Emu41 was doing it with an integrated virtual HPIL loop... and was even supporting the PIL-Box, not to talk to ILPer but to control real HPIL hardware.

The DM-71L should sport this feature as well.

DM-71L ?? Did I read correctly ?

A subtle suggestion.

A subtle suggestion attached to the end of a sledge hammer!

How cool would it be to have a SwissMicros version of the 71B with FRAM71 capabilities and a built-in PIL-Box?


RE: Loading ROMs in DM-41L? - TASP - 12-25-2015 12:28 AM

and the 71-41 emulator

WAY COOL?

RE: Loading ROMs in DM-41L? - Geoff Quickfall - 12-25-2015 12:34 AM

But give me 41 with printer IR,

Almost as cool!
