The top of those two cards looks exactly like the one I have, but with a 040/40 processor. I also have two of the older 040/25 cards with the 128k L2 cache daughter cards. Thanks for the info.
Jeff wrote; There were two main revisions of the Turbo040. The earlier versions were built out of a bunch of programmable logic device chips (bunch of square chips with 'J' leads). This version has a removable 128K cache daughterboard on the back--or lacks the cache but has a connector at the top back of the card for the cache. The later version, which it sounds like you have, was the "ASIC" version. It has the 128K cache soldered down to the main board, has no daughter board and no connector on the back for a daughterboard. There was a recently completed auction for a pair of the ASIC version here: <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2762078238&ssPageName=AD ME:B:BN:US:1> The two distinguishing features of the ASIC version are the lack of the connector for the cache daughter board on the back, adn the presence of a large square chip in the middle front of the board, in addition to the 68040 CPU. I have several of the 25 MHz Turbo040 in the earlier version and found that they upgrade to 40 MHz just fine, by removing the oscillator and replacing with one that runs it at 40 MHz. Of course, since yours already runs at 40 MHz that doesn't really matter in this case. Jeff Walther -- Compact Macs is sponsored by <http://lowendmac.com/>.
