I already asked this on port-VAX, figured I'll try here, too. Can anyone provide one of the following: 1). Confirmation or denial that the address jumpers on the TQK50 (M7546) and the TQK70 (M7559) are laid out in the same pattern, bit-wise? In other words, does each board share the same pattern for setting its address? 2). A jumper chart for the TQK70, or jumper setting info to set it to the primary tape device address. Thanks much. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com // E-mail: kyrrin(a)bluefeathertech.com Amateur Radio: WD6EOS since Dec.
