Apple /// : Diags?

[travis@cluracan.remove-this-part.org (Ward C. Travis)]

I have an Apple /// here that I think is a 256kb machine, but which has a
sticker on it marking it as a 128kb system. I've opened it; there's a long
card in there fully populated with two rows of DRAM DIPs. The memory card
art declares it to be the five-volt Apple /// memory card.

I know that, somewhere in the ROMs, there's a diagnostic I can run. What
is it's address and will it confirm the amount of memory in the system for
me?

The only system disks I have for it are the Pascal (UCSD) system, and I
haven't tricked that into revealing the amount of memory in there yet.

Any tips are welcome!

Thanks,
