Photographs from the initial disasembly. There's a lot
of seemingly pointless detail here, but might help solve problems
with broken wires, rebuilding the rotted foam air seals,
etc.

Operator control panel. See Programmers
Manual for details. |

Operator control panel, door
closed. |

Overall view of CPU cabinet, cover removed
(normally tilts forward, removed for examination). Rotating
memory on left, Memory Controller PCB, mounted vertically along
left edge of memory just visible, two 7-pin mini tube
connectors to memory read amps on memory mounting plate. Power
supply lives under the memory, card cage to the
right. |
 |
Overall view of the guts, cover removed,
control panel assembly open showing top of Flex controller
PCB. |
 |
Top view, cover removed. |
 |
Inner control panel assembly, covering top
of card cage, open. |
 |
Rear I/O connectors. |
 |
Mercury tilt switch under thermistor mount,
wired to; presumably disables overheat when cover
open? |
 |

panel. |

Inside of cabinet showing foam air
seals. |

Foam air seals inside cabinet. |
 |
Cards installed in cage, connectors
attached. May or may not be correct configuration (but
backplane is a plain buss). |
 |
Overall view, right side, cover
removed. |
 |
View of backplane, power supply below,
memory removed. Mercury electro-chemical elapsed-time meter
visible; seems unreadable, maybe exceeded
full-scale? |
 |
Backplane detail. |
 |
A "field ECO", where ECO is "Engineering
Change Order". In other words, a factory screwup; the
thermistor meant to monitor card cage temperature is shielded
from some hotspot on the Flex controller PCB by this taped-on
piece of teletype paper. |
 |
Rear view, rear panel dropped
down. |
 |
Inside rear panel, connector
wiring. |

Bottom of main chassis. |

Rotating memory, overall top

Rotating memory, head-mounted diode
switches. |

Memory controller unfastened, showing
connectoring. Big caps are power supply; contactor and AC
capacitor are for memory motor, barely visible as black
vertical cylinder behind other components. |
 |
Memory controller, detail. |
 |
Memory motor wiring detail
(disassembly). |
 |
Side view of memory assembly. Memory
(platter) is enclosed, but not sealed/gasketed, so I ahve to
assume dust/grit infiltration. Will be restored by professional
disk-data-recovery people. |
 |
Memory assembly, detail. Unfortunately out
of focus, but there are plexiglas-head assemblies placed around
the axis, each shifted to cover the 64 tracks. |

Memory assembly, detail. Bad

Memory assembly, detail, clearly showing
head assemblies and read amps. |
