I don't remember any such thing. Perhaps people would do basic
operations from the console switches -- see if memory appears to
exist, that sort of thing.
Here's a quick memory test: load address 157776, deposit 014747, load
address 157776, start. Result is that all of memory (the lower 28 KW
that is) will be filled with 014747. It will probably stop with PC =
0, but I'm not sure of that.
