Black Mac manufacturer found! Candes Systems of Harleysville PA

		MacIntosh SE 30 1891T This very odd MacIntosh is a fine specimen of a Tempest shielded (hence the "T" in the model number 1891T) MacIntosh SE 30 computer made by Candes Systems of Harleyville PA. Made of metal (the case) and with a handle to be more easily carried (we suspect by an officer or other operative) the interior of this Mac was designed to foil any snoops. More information will be provided here, kindly given to use by Candes Systems
	Perhaps the most striking feature of the "Black Mac" is the flop down front, revealing an opening for a removable hard drive (Syquest drive we are told).
		This cover is in turn studded with copper coils indicative of the famous "tempest" shielding used by government agencies and others to prohibit electromagnetic impulses from exiting a device and to thereby be detected. You would be surprised how much can be sensed from a distance from common devices (the LEDs in your router, they produce a discharge that can be read from some distance by sensitive devices).
	Around the back is this weird bulge serving what purpose we do not know. The faceplate is missing. There is a label naming the manufacturer of this case. We have been assured by Apple folks that based on the properly designated model number on the front that this is a "real" MacIntosh model. So did this "black Mac" fight Star Wars for Ronald Regan back in '87-88? Anybody out there have any more information about this rare and precious piece of MacIntosh history? Please, please contact us!

The black mac, the se/30t with the flip down front. I looked closely at your photos and the black drive in the front is not a bernouli drive. It is a syquest drive, original 40 meg cartridge. My father ran a graphics business and i have sen literally hundreds of the disks for those and we owned quite literally 25-26 drives that used those cartridges. Later models of the drive supported 80 meg and were silver instead of black. Just thought you would like a little more fact on this machine =)
