So far I've only run the external SCSI ZIP drive but that has worked fine so far. It's a shame to have to hang slow devices like ZIPs, CDRs, Scanners, etc. Of more concern is cable lenght. No bent pins in any connectors anywhere. The old saying 'Buy in Haste, Repent in Leisure' comes to mind.
Early buyers get to find out where all the initial problems are.
I'm confident most will be worked out in the future but as mentioned here early on, this is one thing to be aware of when making a upgrade vs a new model system purchase decision. Guess it was lost in the mail. A talk with Orange Micro's tech suuport revealed that their emulation layer cannot deal with Apple's new Apple Enet extension. Frank Bernier wrote that to his recollection tomorrow will be the 15th Anniversary of the Mac. So the problem I see is not due to a 3dfx card.
