The Fireball is a full length Zorro II SCSI card with enough space to mount a hard drive onto the card, however there is no power connector on the card so you must use one from the PSU. It claims a sustained rate of 650K/sec using DMA, however to me that seems very slow, even compared to other cards of the same vintage. The card contains status LED's and a switch to enable of disable autobooting as well as two onboard 50pin SCSI connectors and an external DB25 SCSI connector.
