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...

Well, thank you VERY much, Eric!
I didn't spot this page before on Christoph's site.

Finally I've them all. :)
