   APPLE IIC MOTHERBOARD UPGRADE: CHEERFULLY HONORED AT LOCAL APPLE DEALER
   .......................................................................


I brought one of my IIc Apples to a local dealer who did the motherboard
upgrade without charge --- the computer now has 32K ROM, has the power-up
self-test, and can operate the Unidisk 3.5" drive.  Previously it was the
"original IIC," and now it is the "middle IIC, known also as the
"Unidisk IIc."

I also dropped off three more "original IIc" computers for their upgrades.
These were IIc's that are owned by my college.  I felt they should be
upgraded because our college is being fully wired with fiber-optics data
lines which eliminate the need for modems, and which can operate at the
highest speed of the serial port: 9600 baud in the case of the IIc.  Students
are signing on quickly to the internet access, and, eventually, the college's
IIc's will be connected to the net.

The upshot of all this is that owners of the "original IIc" model can still
get the free motherboard upgrade by asking for it.  You should be prepared
to show that you own a high-speed modem (e.g., 2400 baud or faster) that
does not work with the IIc, or alternatively, show that you own a Unidisk
3.5" drive that does not work with the computer.

The eligible IIc computers are the early models with serial numbers on
the bottom-casing which are BELOW D50000 (letters are mixed into this
sequence).
If the first two characters of your serial number are D4----, then you are
likely eligible for the upgrade.   Another way to tell whether your IIc is
eligible for upgrade is to hold down the two "Apple" keys at power-up.  If the
IIe-style "checkerboard" self-test pattern appears, then you are already
at the middle- or late-model motherboard.  But if you see instead a weird
progressively moving wavy line pattern, then you have the upgradable older
version of the motherboard.                   sebugg
