The "RK11-D and RK11-E moving head disk drive controller manual"
(EK-RK11D-MM-002) states in par. 2.5 (Installation Procedure) that the register
and vector addresses of a RK11-D can be configured by "seven interrupt vector
address jumpers and eight address selection jumpers of the M7257". The manual
however doesn't state the address range that can be configured by these jumpers
and refers to engineering drawing D-CS-M7257-0-1 for that information. I found
these drawings in the RK11-D Engineering Drawings but cannot find information
in them on the valid address ranges. Therefore my question: what is the address
range a RK11 controller can be configured for?
