I will pass on 8 and 14 inchers....(:+}}... But I was figuring
1 or 2 gig drives would be what I have plenty of to install.
The controller is the dilogic controller.
Are there any tape support bits for dilogic controllers that I
should find, things like formatters, etc?
Anyone have a spare copy or xerox of a dilogic controller manual?
I have essentially nil DEC docs, so am shooting from the hip on

I could not get it to recognize a pair of added in RZ56's.
Is there something strange like special formatting or such that
I need to do to get it to recognize more drives?

OK, now we are getting to the nittygritty. What are the switch settings
to use a TK50 as a secondary controller?

OK, I have heard of this infamous tape, and I thought I had one in my
tape collection, but I can't seem to find it.
What is needed for dilogic controller formatting?
