My colleague Steve Wilson is running MAPLE  on
his  3B1 with the  67 MByte disk and 4M RAM,
and increased his swap space to 1.5 Mbyte (?) after
consultation with the HOT-LINE folk.

According to Wilson, there is a secret non-publicized
entry into the Rel 3.5 Diagnostic disk that enables
one to do wondrous things.  I have not tried this,
but he has and it works;

To change swap space, with the 3.5 Diagnostic disk
in, when the menu shows up, don't type 1-7, but type
 
	s4test <return>
	31	"
	i	"
	drive i	"
	sb 0	"
	wr 0	"
	q	"
	2	"

and then answer the questions.

Other options,  to get disk data:

	expert > 6,12
	expert > U	(to exit)

Does anybody know of others?

Incidentally, there is a maximum size to the
swap space that can be allocated that is surprisingly
less than what I had expected -- I don't recall the
figure, unfortunately.
