[comp.sys.amiga.tech] A2000 card slots

c8625863@cc.nu.oz.au (11/09/90)

I am currently at University designing a piece of hardware for a university
project which uses an AT-compatible computer.  The hardware will use the AT slot
for talking to the card from a computer.  My question is... is the "AT slot" in
the Amiga 2000 the same as an IBM-compatible AT slot???  All I will be using
the slot for is the 8 address lines and the 8 data lines and maybe the power
lines.  I may also need to use an interrupt line of some sort.

If the slots are the same,  it will enable me to program an Amiga to perform
the required task and might place the Amigas in industrial applications.  I
would really like to see Amigas being used like this if possible.

I haven't made the final design layout yet, so I would appreciate it if I could
know in advance.

		Thanks in advance,

IBM???  Are they AMIGA-compatible???

The slots are identical to an AT, BUT: They aren't connected to the main
Amiga processor at all! They live in free air, until a Bridgeboard or
some other intelligent device connects them to the Amiga world. The only
thing provided is electrical power. I heard, though, that are said to
exist boards similar to the bridgeboards, but without the PC on them,
that connect the PC/AT address and data lines to the Amiga bus. But I
don't know anything about the product name or the manufacturer.

	Yes, but realise that these lines are not in any way connected to the
Amiga bus. You need some sort of 'dumb' bridge board to access them.

	What you'll want to do is design a simple bridge that lets you access
the ISA slots via an Amiga autoconfig board. Then you can access any PC type
peripherals you want, by simply mapping them into the Amiga space and writing
a device driver or two... :-)

	Commercial plug time... :-)
	
	NES, Inc. makes a prototyping board specifically designed for this type
of project. Our AM-200A board has both the Zorro II/III connector and the ISA
connector. It also has a fairly decent ground and power plane, with a couple of
15x15 grids for PLCC or PGA packages. Retail price is $49.95 and can be bought
through better Amiga dealers or direct from our marketing people. Call Software
Technology, Inc. at (503) 653-2090 or write 10610 SE McLoughlin Blvd., Portland
Oregon 97222. I don't know what they change for shipping, but I'm sure Randy
or Bill could tell you. :-)
