VME? related to College search.

Certain Sun products also used it but I defere to those experts for further Sun comment. VMEbus was invented by John Black and others at Motorola in 1983. Came from the now-obsolete VersaModule bus structure Moto had since I think the mid-70's. Basic form factor was the Eurocard with DIN 46xxx connector (can't recall DIN number at moment). Hence, VMEbus = VersaModule Eurocard bus. Quickly became a standardized bus protocol worldwide. Moto, Mostek and Philips were earliest suppliers of hardware. Others followed. Still somewhat popular and well supported today. The 68k processor family was the most used uP. However, Intel uP's, Moto's 88000 RISC uP, some Transputer devices and other uP's were also used in VMEbus module designs. A fairly recent extension of the VMEbus protocol, VME64, extends the bus to 64 bits. The physics community is a major user of VME64 nowadays. Start by looking at this URL from eg3 which has a good list of VMEbus resources: http://www.eg3.com/indc/indcxvme.htm. VITA - The VMEBus International Trade Association, has a URL: http://www.vita.com/ . You could find more info and links there. Should be as common as it was in the States as it was found usually in embedded industrial control and data collection systems in factories, etc. Of course, the PeeCee stuff replaced some installations if the user wanted to move to or start his/her design using the Intel processor or go for a design 'on the cheap and dirty' as VMEbus products and s/w could be a bit pricey. Multibus I and II and, to a smaller extent, STDbus and G64 were competition to VMEbus. I agree. Algonquin is fine with including VMEbus and other industrial busses in their course structure. PeeCee could be included but for critical real time apps it should be stated that VMEbus and its board products and OS's are one the several non-PeeCee systems which really shine. Yeah, well the on topic ones are fine from us, but . . . ;) Regards, Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.ggw.org/awa
