Resent-To: backmod Resent-Date: Wed, 27 Oct 1993 18:56:02 PDT Resent-From: Info-Mac Moderator <macmod@camis.Stanford.EDU> The summary that I posted posted in Info-Mac and comp.sys.mac.hardware a few days ago ("SUMMARY: Is the Apple 8*24 GC video display board worth something?") stirred a few more comments that relativize the very negative opinions that were expressed. In short: The card can be used as a good non accelerated 24 bits color card if it is used with the proper drivers (8*24GC 7.0.1 driver and "Cache On" extensions). The possibility of extending its GWorld memory (with the same SIMMS as for a MacIIfx) makes it useful for some applications. Newer versions work with a 832x764 pixels 16" monitor. As the price that I was quoted (400$ second hand) is still more than the standard 24 bits card (330$ list price in Switzerland), I won't buy it. Here are the comments I received. Many thanks to their authors who took the time to write to me! For those who missed it, the first summary is available by FTP on sumex-aim.stanford.edu in the file /info-mac/info/hdwr/worth-of-8-24-gc-card.txt [Note to the Info-Mac moderator: could you please append this second summary to that file? Thanks!] ================================================================ From: (Bailey Szeto) <bszeto@netcom.com> Here's some additional info/clearification on the 8.24GC board. I recently was employed by Apple to do some compatibility testing and got the chance to play with the 8.24GC a bit.

This was the last change to the card, in fact the code name for this project was "Cheap Date". : - video: RS-343 and RS-170 (NTSC, interlaced); only 256 colors with "Apple : convolution" for flicker free display. : - extensibility: : 2 SIMMS slots to add up to 8 MB extra memory for "processing : large off screen graphics" (retranslated back from French :-), : notice that it won't let you use a larger monitor). The extra Simm slots are for a expanded "GWorld". It is indeed for processing large off screen graphics, but not many programs take advantage of this. : Facts from Larry Pina's book "MacIntosh Repair and Upgrade Secret…
