This was way back in 1990(?) or so (memory fails me.. i think I need one of those RAM upgrades for humans) Being a techie, I naturally had to void the warranty and take the thing apart. And, what did I find inside? Sitting pretty right next to the motherboard was a REALLY TINY 2.5 inch HD. And yes, it was SCSI, because it showed up in the SCSI device list control panel. Naturally it needed a special interface (it looked like a really thin ribbon cable) because the drive itself wasn't physically big enough to house a standard 50-pin SCSI connector!
