Running a MacroSystems Warp Engine '40 in my A3000D. The int2 is not needed with this card as I understand. Comes with a jumper wire. Limited to 64 meg ram onboard with the A3000 model of the card because of C= brilliant case size reduction idea. I'd imagine with enough modification, the A4000 model with 128mb ram of the Warp'40 could be fitted. I've made some vent holes in the drive tray to help the cpu fan breath. The onboard scsi II header [strike]is[/strike] would be nice if I could get it to function properly...
