tape and the RCA carts were maxed out at 3 minutes. The pictures on  
this website showing the carts side-by-side are not to the same scale.

		I offer:

	The ACR-25 carts could hold up to 6 minutes of tape running at 15ips.
	One of the photos on Labguy's website is of both carts together.   
Kinda hard to show carts as 'not to the same scale' if they are  
together in one picture.  The two carts are not significantly  
different in physical size.  I've worked with both machines.  If  
anything, the Ampex cart is slightly less thick than the RCA cart, but  
wider and higher to allow for more tape.  The RCA cart is a little  
bigger in thickness, possibly to accommodate the mechanism to operate  
the two aluminum doors, but it's not as wide or long as the Ampex cart.
	BTW, not many know that Scotch made a cover for the Ampex cart,  
designed to only protect the tape from dust during storage.  The cover  
must be removed before the cart is placed in the machine.  I own an  
Ampex cart including the cover:
