The BA123 Enclosure is a QBUS mounting box from DEC which is available a caster-mounted single-cabinet form. It is the 'bigger brother' to the BA23 Enclosure, and the sibling to the BA213 Enclosure.
It contains a single, 13-slot, quad-height backplane; the first 4 slots are Q/CD slots, the next 8 are Q/Q; the final slot is for a signal distribution board, for the connection of mass storage peripherals. That backplane cannot be expanded.
