Description
Digital Equipment DEC BA213 VAX 650 Chassis 70-24227-03 KA650 TK70 RA70 Cards
The Digital Equipment Corporation BA213 is a floor-standing tower chassis from DEC's VAX 650 midrange computer line. This unit (part number 70-24227-03) is loaded with a full complement of DEC Q-bus and BI-bus modules, a KA650-AA VAX CPU, a TK70 streaming tape drive, and an RA70 fixed disk drive. One of the two installed H7868-A power supplies is faulty and will need to be repaired or replaced before the system can be brought to power — this is a known defect clearly disclosed in the condition notes.

Applications
The DEC BA213 chassis is part of Digital Equipment Corporation's VAX 6000 / VAX 650 midrange computing line, introduced in the mid-to-late 1980s. The KA650-AA processor (also known as the CVAX chip) powered VAXstation and VAXserver configurations running VMS (later OpenVMS) and Ultrix. These systems were widely deployed in scientific research, engineering workgroups, university computing centers, and commercial data centers throughout the late 1980s and 1990s. The BA213 backplane accommodates a mix of Q-bus and BI-bus modules, making it a flexible platform for storage, communications, and networking expansion. The TK70 tape drive uses CompacTape II cartridges (296 MB native capacity) and was the standard DEC backup medium of the era. The RA70 is a 280 MB SMD-interface fixed disk commonly paired with VAX 650 systems. Today, BA213 chassis with full card complements are sought by VAX enthusiasts, retrocomputing collectors, and organizations maintaining legacy VMS environments.
This Digital Equipment DEC BA213 VAX 650 chassis (70-24227-03) is being sold in used condition. It comes fully loaded with all the cards and drives listed in the specifications — KA650-AA CPU, TK70 tape drive, RA70 disk, dual MS650-BA memory boards, KDA50 SCSI controller, KFQSA SCSI adapter, TQK70 tape controller, CXY08-M async comm, DSV11-SA sync comm, and OELQA-SA Ethernet module. However, one of the two DEC H7868-A power supplies is faulty and will need to be repaired or replaced before the system can be powered on. The second H7868-A unit appears intact. The chassis itself shows normal wear consistent with former professional use. Please review all photos carefully and contact us with any questions before purchasing.
