RE: HP41C with Rp Pico attached
Thanks for the update Meindert!

I'm following your progress on the PIO with interest!

The disassembler works very well now, so I can trace execution (without missing any lines) without any problems.
All is still done in the Pico, but I think I will move the disassembler to a PC application instead so I could add eg. symbols support and add some filtering in the Pico instead (eg support for start and stop addresses).
I noticed that if I load the Pico with that as well, I start to get buffer overruns and start to drop instructions.

I will also try to drive FI as well, that way I could emulate peripherals, ie indicating that there is data available, and then provide data that could be received by the HP41.
I started to look at this, and emulating the Wand (data available flag and data buffer) looks manageable, so that it should be possible to easy send a Focal program over USB, which is then stored directly into the 41 RAM.

This would make it very easy to transfer a program from a PC directly into the 41 without going through eg. a HPIL drive.

Let's see if I can find time for all of this ... Wink

Cheers,
Thomas
