Since i have had them i had always wondered what the difference was between this version and the 1.0.2 versions that came out later. I upgraded one card myself to 12.5Mhz and 32K cache and that board doesnt have any logic chip sockets at all. My other one I sent of to get upgraded to 12.5Mhz and 64K Cache and i think it came back (was about 5 years ago so not 100%) with logic chip sockets and labels for which chip goes were... I have a picture of the card ftp://drewbie.dyndns.org/UPG_ZIPGS.JPG My question is what did the logic chips do? and is it something i can add to the card to push them to higher speeds/other benefits?Interesting. I just came into possession of Zip GSX 1.01 and noticed the lack of those chips. Wasn't sure if it was practical to upgrade it or not. Can anyone else provide some data points on this? Henry Courbis? What's your experience with v1.01 vs. 1.0.2 Zips?Somehow I doubt it's just a matter of installing the two 74F parts. Somewhere, something else must have changed (jumpers? traces cut?).
Everything listed at ReactiveMicro as an upgrade is more or less a hack to increase speed and cache ram. Store bought 1.01 vs 1.02 is probably a small logic chip change, nothing to be concerned with. Mine is 1.02 and is standard 8 MHz, and 8K cache out of the box. I believe they updated some near the end of production to 10/16 for the sake of sales.
