I'm trying to identify an industrial computer bus type -- probably 80's era. Typical plug-in static memory card (AYCAD CMS 04 256BH) measures 12" x 6-1/2" (not including edge card contacts -- 6-3/4 deep with them). The 12" long edge shows two sets of edge card contacts: One is 86 contacts with spacing of 0.15", and the second is 60 contacts with a spacing of .010" Any ideas what bus this is? Andrew? :scratch: |

Picture Steve would help. Sure those are 0.15 and not 0.156 spacing? |

Nope, not sure at all, Andrew. Brought neither my specs, nor a camera to work today. Getting forgetful and still refuse to carry a phone in the pocket. So, yup probably .156! More info: 1.) The motherboard backplane connector has only the 86 contacts. The 60 contact strip on the card goes to a separate board, so the 86 contact bus is the one of interest. Ignore the 60 contact mis-info. 2.) AYCAD seems to be a French brand name. |

The only bus I can find which matches that spec is the Intel Multibus 1; 43/86 edge contacts @ 0.156" spacing. Spec: http://bitsavers.trailing-edge.com/pdf/intel/_busSpec/9800683D_Intel_Multibus_Specification%20Jun82.pdf (see page 4.4, aka p40 in the PDF) Wikipedia's sparse page on it: https://en.wikipedia.org/wiki/Multibus HTH! |

It was Multibus that I had in mind but I was fairly certain it was 0.156 pitch. So we need that pitch confirming Steve :thumbup: |
