I recently ran into one of the MAME developers, and he was very interested in adding support for the Jornada 720 to MAME.
Specifically the Jornada 720 since MAME already has Intel SA1110 emulation implemented, and there being a lot of documentation for the Jornada 720.

I sent him all data sheets of the components for now.

He asked me to provide him a ROM dump as well. I don't have one right now, and I don't have a CF card to install _dev_null's Devuan right now either and do one myself.

So if anyone has a ROM dump of a Jornada 720 (and ideally also Jornada 728, in case they are slightly different) lying around, please step forward

I'm excited to see what comes of this!

I didn't think there were any in the public domain?
If you get them, shoot them over to me, we can put them on repository.hpcfactor.com

Ok so I'm working on a tool to just create a ROM dump. It's working already, but I'm not sure if I dump the right stuff

So anyone here who knows more than me, are these assumptions correct:

1. Windows CE has no memory protection, so I can just read and part of the ROM anytime, right?
2. The J720 ROM is 24MByte
3. The ROM is mapped from 0x0000000 to 0x0BFFFFFF

(added bonus picture even though there's not much to see)

I've found this online:

https://wwwcip.informatik.uni-erlangen.de/~simigern/jornada-7xx/docs...

According to that, System Flash / ROM is 32MB.
