8 Line Asynchronous Multiplexer for PDP-8 and/or CESI Omnipac Computers

This data sheet describes the Computer Extension Systems, Inc. (CESI) SLZ8, a single-slot, hex-width asynchronous multiplexer board designed for DEC PDP8-A and CESI OMNIPAC computers. Key features include:

• Performance: Provides eight channels with RS-232-C compatible serial I/O and a 64-character "silo" buffer to manage data reception. It supports 16 switch-selectable baud rates (50 to 19.2 Kbaud) and programmable character formats.
• Modem Support: Offers varying levels of modem control across the eight lines (full control on line 3, partial on lines 0-2, and limited on lines 4-7) and supports several Bell-series modems.
• System Integration: It is designed to work with the DP8E 16-channel distribution panel via a CC05W cable.
• Maintenance: Includes internal loopback capabilities for testing control boards and UARTs.
• General: The product comes with a one-year warranty and requires +5V, -15V, and +15V power supplies.
