I have a few MLSI-DZ11 serial multiplexers which I purchased without
documentation. Does anyone know if these boards are 100% compatible
with the DZV11 (except for the additional 8 ports)? Do these boards
provide full 22-bit addressing?
Also, I would appreciate an address for MDB systems if they are still
in business.
Thank you,
Richard

However, the MDB boards are 100% compatible with the DEC boards. (50 to 19.2Kbaud, prog. data and parity). They have a 4 level interrupt. They are not 22-bit devices (only DMA devices (disk, tape, and some serial multiplexors (DHV11) are). This board will work in any Q-BUS system, as long as the operating system supports the device. Sorry, but I don't have the pin-outs for the connector or info on the switches (ADDR and VEC). MDB is (was) located at 1995 North Batavia St., Orange, Calif. 92665, phone (714)998-6900. MDB was also sold in Canada by TRANDUCTION (Toronto). Sorry, no address or phone available (call 416 info). If you have any other questions, feel free to call directly via BITNET, as I'm using a DEMO account to read NEWS. - Mike Marak BITNET MARAK@VAX2.CONCORDIA.CA EMC LAB PHONE (514)848-3118 Concordia University Montreal -
