[comp.sys.amiga.hardware] A2620 ZIP part number help?

[short question follows long story]

As a registered Canadian Amiga developer, I have call to make purchases
from the parts department at Commodore here in Toronto from time to
time.

In one case a few months ago, I purchased, among other things, some
DIPs for an A2091 and some ZIPs for an A2620.

The parts that I was given as the DIPs were big square chips, that
even a software guy like myself could tell weren't even RAM.  After
showing the gentleman at the parts counter that they wouldn't fit
in the sockets on the A2091, I managed to get him to go find someone
who came back with different (right size package) parts, which I took
away and installed.  4 of the chips failed to work.  On returning
them to C= they determined that these chips were the wrong part number
again, and replaced them.  They've worked ever since.  End of that
story.

When I asked a tech. at a C= dealer to install the ZIPs in the A2620
(without sockets), he refused, saying he thought the chips were the
wrong part.  Given my experience with the DIPs from the same order,
I figure this as a reasonable possibility.

So, armed with the part numbers from the A2620 manual, C= invoice,
and the chips themselves (all different), I called the parts department.
I was told that their inventory computer system was down, and to call
back in a few days.  When I did so, I was passed on to a tech. who
informed me that he couldn't tell me if the chips were the right part,
but said if I tried putting them in an (socketed) A3000, and they worked,
that should indicate that they were in fact the right part.

Now, that is probably correct.	I could do that, or try to get C= to
do that, or install sockets in the A2620 and check them out empirically.
I may end up doing that, but it is somewhat unsatisfying.  I don't know
why the C= parts department is unwilling or unable to check their
inventory system, or chip manufacturers data books to find out just
what the chips they sold me are.

In lieu of help from that quarter, is there a h/w guy out there who
can tell me something usefull from the following part numbers:

On the ZIPs: AAA1M204Z-06 NMBS 4

From the C= invoice: 318099 05	p.m.V44256L80 A3000

From the A2620 manual: 414256-10

Now, I'm pretty sure, that the C= part number is for a compatible
part, but confirmation from someone who knows for *real* *real* sure,
would be nice.

What would make me really happy, is if someone could tell me for
sure that the part number on the ZIPs identifies them as definitely
either compatible or incompatible with the 256 x 4 chips that the
A2620 wants.

Why didn't Monty Python write a sketch entitled "parts department"? :-)

Disclaimer: This is not intended as a public spleen venting against C=.
The comedy above may not represent the whole of C= Toronto's parts
department's typical behavior.  It certainly does not reflect on C=
Canada as a whole, and has nothing whatever to do with C= Intergalactic.

P.S.  This is my first test of a newly installed uucp 1.13 dnews for
posting, so please excuse any silly headers.

Don't apologize for silly headers.  In some cases, they are not at all silly,
and in others, they may be slightly silly, and their full silliness may be
exploited with government grants.
