new user 41C memory

[institches]

Hi all,

I'm fairly new to the 41C and I am having trouble with memory allocation.
When I check the default registers, after a reset, I see 00 REG 46 which is correct.

After running SIZE 000 I see 00 REG 191, where I expect to see 063. There are no modules plugged in at all, although I have had some plugged in prior.
This made me wonder if it was mislabelled and it was actually a 41CV but I think I proved it is not a CV by trying to run the EMDIR command and it returned NONEXISTENT.
Now i'm starting to wonder if it is faulty or if this is normal behaviour?

Any help would be appreciated.

Kind regards,
Gary
