Hmmm. We do it all the time in Dell as well as other machines. "mkdev tape"
should look like:

	Tape Parameters		Values	Comments
	---------------         ------	--------
	1. Controller Type	3	1 = type A, 3 = type W, 4 = type E,
					5 = type M, 6 = type T or 7 = type X
	2. DMA Channel		1	1 or 3
	3. Interrupt Vector	5	logical vector number
	4. Base Address		0338H	i/o addresses start here
	
	Zero Values Imply Auto-Configuration

Maybe there is something special about the 0x338 address. I recall some 
difficulty trying to use 0x300.

Oh. Now that I think about it, if the pins on the bus card point up
(as opposed to out), you have the "Wangtek/Tecmar Single-Chip Tape Controller"
and will need to either XNX155B or XNX149 your XENIX.
