The compaq system I talked about repairing will go into the old case. It's a far cry better than the original case, and this new cooler master is a better replacement to the other beige box :) Mon, 08 Jan 2007 22:41:37 -0800 http://www.applefritter.com/node/20000 This is the ohio scientific challenger from 1978 - the 8k microsoft interpreter in ROM was written by Bill Gates.

It was purchased by my employer back in 1989 or 1990, reportedly for around $40,000 (though I never saw the purchase order.) It is essentially a modded IIfx in a giant steel case with oodles of space for disk drives and cooling gear. I haven't weighed it, but it must tip the scales at well over 50lbs. The case is all steel; the front panel has a key lock, is hinged, & pops off quick as a wink. Behind the front door is a reset switch, a programmer's switch, and an ADB lock switch. With the front door open, remove a couple of screws & the top slides forward a smidge, then lifts off to reveal the I/O ports and a row of 6 NuBus slots. With the door open and the top removed, you loosen a row of screws down the left side and the side panel swings back to reveal the interior. Inside the case, the first thing you notice is a huge cooling duct; it pulls air across the RAM modules. The RAM that's in the thing is unlike anything I've seen elsewhere; 64 pin SIMM's that are as tall as they are wide. Huge. I snapped a few photos this afternoon, but the lighting was poor and a lot of them came out fuzzy. I'll take some more later (using a tripod!) and will post them later for your drooling pleasure!

And plastic simply isn't good enough for the army. The TPI-863, made by Techmatics Technologies, Inc., solved this problem for the military by recasing the Macintosh Plus in a steel case. This machine was built to meet Tempest standards. "Tempest is a term given to computers that were shielded from electromagnetic energy escaping into the rest of the world. The purpose was to keep someone from being able to read what was being displayed on the screen, which is apparently readable from some distance away. Lots of government computers were rated tempest to protect our national secrets."

Unlike the Techmatics unit, Systematics chose to leave the Mac in its original case. While Techmatics changed the case, but left the actual Macintosh untouched, Systematics did the opposite, removing connectors and changing switches. [center][image:3335][/center] Front of the machine. Nothing unusual except for the square slot cutout where the keyboard RJ14 connector used to be. [center][image:3336][/center] Back of the machine. The brightness nob, power switch, and power cable have all been replaced with componets meeting TEMPEST standards. Also note that many of the ports have been removed, particularly that for the floppy drive. [center][image:3337][/center] The backside label. The manufacturer (or rather re-manufacturer) is Systematics General Corporation of Sterling,Virginia (a wholly owned subsidiary of Atlantic Research Corporation). [center][image:3338][/center] Guess what? That slot is another Sony 3.5" floppy that has been installed internally. The slot has been manually cut out. [center][image:3339][/center] A close-up of the keyboard connector. It attaches to the unit via the modular plug. Then the panel screws on to the front of the machine. The duct tape looking piece of material is a metallic mesh that prevents leakage of emissions. Note the brass gasket attaching the shielded cable to the keyboard housing. The metal box on the back covers the old keyboard connector.
