Adapter for LSI 11 and Unibus allows remote Drintina

MDB Systems has developed the MDB/ MLSI-PLLAI1, a dual- size adapter module for DEC computers. The MDB/ MLSIPLLAI I provides long-line differential capability to MDB's printer controllers for LSI-I I based systems, allowing placement of the printer up to 3000 feet from the computer.

The MDB/ MLSI-PLLAI I converts the TTL signals from the MLSI-LPI I, which operates printers with Centronics or Dataproducts and other interfaces, or from the MLSI-LPI l- A, which operates printers with a Data Printer interface, to RS-422 balanced differential driver/ receiver circuitry. The module can be placed before or after MDB printer controllers or adjacent to them in Q-bus backplanes. If it is placed in Q-bus slots, the incorporated jumper provision allows DMA priority and grant signals to be passed, and the module acts as a bus grant card.

The PLLAI I can also be used with all MDB printer controllers for Unibus and VAX systems to provide long-line capability to these computers. When used with Unibus controllers, the module occupies the A-B connector positions of the Unibus backplane.

The module has five edge-mounted LEDs that instantly indicate data strobe and acknowledge/demand signals and printer status signals such as On-Line, Ready, and Fault.

Two cables are provided to allow connection of the MLSI- PLLA 11 to MDB-manufactured LSI- I I Q-bus and Unibus/VAX printer controllers. The module can also be used with DEC manufactured controllers if the user fabricates his own connection cables.

The MDB/MLSI-PLLAI I costs $300 in single quantities with delivery 30 days ARO.

(Image Omitted: The printer long-line adapter module, MLSIPLLA11, from MDB Systems allows printers for LSI-11 and Unibus systems to be placed up to 3000 feet from the computer.)
