CAT 2 on a HP-71B?

[Matthias Wehrli]

Hi. does anybody know, if there is a command like the HP41 "Cat 2" on a HP71B? I have a lot of Modules and EMROMS where I do not know the functions... I only need the topic....

Use function CAT:PORT(n)

Your HP-71B has more than 16K RAM which port number is 0.
You can generate four 4K 'modules' inside:
FREEPORT(0)
FREEPORT(0.01)
FREEPORT(0.02)
FREEPORT(0.03)
Each front port has its own number:
1, 2, 3 or 4
Card reader port number is 5.
For instance in order to read the ROM cat of an HHP 32K Eprom module plugged instead of the card reader:
CAT:PORT(5)
or to display the cat of a 32K ROM in the first left front port:
CAT:PORT(1)
and so on ...
