I also have an Arduino based "Red Eye" to USB serial converter which I may be able to use to receive the ROM dumps straight from the HP-42S or HP-27S to the PC after a bit of experimentation.

The images in this page might be of interest to you. Don't ask questions; just think and experiment...

Hi,

I might have arrived to the party late, but I reaally want to understand giesselink's art exhibition, but I'm bad at understanding modern art

Can anybody PM'me and give me some hints?

Thanks!
