[munch munch munch munch. Boy, that old mother board sure tasted good]
We have just recently received new XTs from our local Computerland. To make
a long story short, just today we discovered that IBM changed the design of
the XT mother board so that it will no longer work with older versions of
their hard disk controller board or will it work with the short slot OMTI
hard disk controller board. The OMTI controller cards work fine in the older
version mother board, but not in the new layout.
We get our hard disks and controllers from Kamerman Labs. I called them today
and I am the first to report a problem. I gave them the information that I had,
ie, the changes to the boards and the new board part number.
There are two ways you can tell that the board has been changed. One, there
are six colored wires added to the component side of the old version board
to make it new and two, the new layout is not green, but copper colored.
At least my new version was copper colored. The new version now has a 74LS32
in the spare chip spot and gets labeld U90.
So, if you buy third party hard disks, make sure it works on the new layout.
I will put up more news as I find out about it. I will have some kind of
comment from Kamerman Labs in a few days.
