VGC and ROM Upgrade for the IIgs
--------------------------------
===============================================================================
Beginning August 1, 1987 TWO FREE CUSTOMER COMPONENT UPGRADES will be available
for the Apple IIgs from Apple Service.
The new ROM corrects minor bugs and provides enhancements for future software
releases.
A new VIDEO GRAPHICS CONTROLLER CHIP (VGC) corrects video display problems
that may occur in double hi-res and standard text mode.
To determine if you need either the VGC or ROM upgrade, check the first three
digits of the serial number on the bottom of your IIgs and use the chart below
to determine what upgrade, if any is required:
Units with numbers 704 or lower require both the new VGC and ROM
Units with numbers 705 - 724 (inclusive) require only the new ROM
Units with numbers 725 or higher do NOT require any upgrade
However, since some systems may have had logic board swaps since date of
purchase, it is useful to to check the individual VGC and ROM numbers on the
main logic board to insure that an upgrade is indeed required. Please refer to
the chart below:
_______________________________________________________________________________
Old ROM: ends in "A" New Replacement ROM: ends in "B"
_______________________________________________________________________________
Defective VGC's: AMI 344SOO46-1 Good VGC's: AMI 344SOO46-2
AMI 344SOO46-A AMI 344SOO46-B
Replacement VGC numbers are: AMI 344SOO46-3
IMP 344SOO46
IMP 344S0056
All registered GS owners should have received a postcard from Apple announcing
the upgrade. If you have not received a postcard, you may have forgotten to
send it in, or your notification may have gotten lost in the shuffle of mail.
Don't worry about it. You do NOT need the postcard in order to get the upgrade
.
CALL your dealer and give him your serial number and ask him to order the VGC
and/or ROM upgrade for you. Your dealer has to order the parts for you, and
he may place you on a waiting list. This is normal.
You will not be able to keep your old ROM. The dealer has to return it to
Apple in order to get his credit and payment. Please don't ask him to allow
you to keep it. He can't.
At this time, we have not received any information on what bugs were fixed in
the ROM and what changes have been made for future software compatibility.
When the list becomes available, and I receive permission to post it, I will do
so.
The dealers also do not have this information.
If your dealer has not heard of the program, please ask him to call his
regional Technical Support Group for information.
