IDS is three volumes of Internal Design Specifications.

All about the hardware and software, including the OS listing.

>What would you be needing this for?

The HP71 processor is used on other calcs, like the HP48, and I'am
developing a multitasking OS for this calc.

I think there was some interesting software in the HP71, the Fort/Assembler
pack for example.

This can be a great help.

Thanks for your reply.
