[comp.sys.apple] GS ROM upgrades

TMPLee@DOCKMASTER.ARPA.UUCP (08/12/87)

Following is the text of a postcard received yesterday:

"Dear Apple IIGS Owner:

Apple is pleased to extend to you a FREE chip upgrade that will enhance
the performance of your Apple IIGS(tm) personal computer.

The Video Graphics Controller (VGC) chip -- which generates the video
output for your Apple IIGS -- may occasionally produce some flickering
and pinktones when black-and-white programs are displayed on a color
monitor in double-high-resolution mode.  Also, some rarely used color
combinations may cause characters to flicker in the standard text mode.

Although you may have never noticed these minor problems, Apple would
like to correct them for you, free of charge.

Simply take your Apple IIGS to any authorized Apple dealer*.  He or she
will replace the old VGC chip with a new chip that resolves these
problems.  And, for any inconvenience youmay have experienced, your
Apple dealer will also install, at no charge, a new, enhanced version of
the Apple IIGS ROM chip.

We hope you will enjoy your free Apple IIGS upgrades.

Sincerely,

Apple Computer

*Visit the authorized Apple dealer from whom you purchased your system,
or call, toll free, 800-538-9696 for the name of the dealer nearest
you."

Note two things:  it doesn't say why the ROM is being upgraded (or what
is in it) or anything at all about a new version of the system
disk/ProDos 16.  No hint whether the problems fixed are why Sargon II
and Robot Odyssey I work on my "new" GS but don't work on the "old" one.
Just got in from out of town so haven't had a chance to call my dealer.
