I just successfully modified my "Type III" 2400C for CardBus (the newest Comet motherboard with no yellow jumpers). I used the MCE technique and hacked Apple USB drivers from Andrew Kershaw's AlkSoft site after an evening of frustration trying to find stock Apple USB software that would load on a 2400C. I must say that this operation is not for the sqeamish. Also, OS8.6 is much more stable and forgiving for CardBus than OS 9. If any listers would like me to perform the surgery, I'll be happy to do so for $100 plus shipping. I can also perform other surgery (like fuse diagnoisis and replacement) and software upgrades as well (by quotation). Here's the software link. THANKS ANDREW!!! <http://homepage.mac.com/alk/personal/stuff.html> -- Greg G 2400C at retrotechpost.com
