[comp.sys.ibm.pc] VME <=> PC bus

mac3n@babbage.acc.virginia.edu (Alex Colvin) (10/04/88)

Is there a device available to link a PC bus to a VME bus?
I have a PC that I'd like to make a peripheral on the VME bus.

If I can't share memory among the machines, is there a fast, simple,
short-haul link?  I'd rather not use a 2.5 meter ethernet.

	There are several manufacturers of PCbus to VME bus adapters, generally
designed to allow a PC/AT computer to driver VME bus peripherals. I believe
Bit 3 is one such company. There are several others. Image Technology uses such
an adapter to have a PC/AT use their VME-based image processing box. Let me know
if you're interested further and need phone numbers, etc.

Ajida Technologies make a unit that gives the PC a lot of control of the
VME bus -- you can watch the bus lines, do all the funny transfers, etc.
The drawback is that as far as I know they make just a MASTER-ONLY
version, not a slave version, so your PC cannot be addressed by a VME
master.  You can detect interrupts and "DMA" out of memory on the VME
bus.  Their address is:

	Ajida Technologies, Inc.
	613 Fourth Street
	Santa Rosa, CA 95404
	PH: (707) 545-7777

If that fails to suit, we make 386 PC-compatables that plug into VME and/or
VXI buses and do both master and slave.  Send me email for more info.

I believe one answer would be Radix Microsystems PC hw/sw on VME boards.

A company called Bit 3 makes a Model 403 IBM PC/AT to VME adapter which is
fairly sophisticated.  It will allow the VME bus to use the AT as a
peripheral and visa-versa.

The board is available with either an 8 foot or 25 foot interconnecting
cable.

The cost of the link is $1280.00  --  not cheap, but what is these days?

Bit 3 is located in Minneapolis -- phone # (612) 881-6955.
