If I understand your question, the VMEbus is a 32-bit microcomputer bus
which is used primarily in industrial computers. 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.

>Don't anyone have graphics of VME stuff like cages, cards, VME
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.
>equipments? And how common is this out in that canadian field?
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 . . . ;)
