Mil-spec board......

[kosmokrator]

hello Friends....
recently i buy a board from e-bay ....Actully the seller say its from Military Aircraft (seller says maybe from F15 have also listed some other mechanic parts from aircraft's)

I liked the board the old Sandwitch like early gold-dip's And the Mystery Under this Cyan Hermetic closed box....
no idea what may inside....can u imagine something?
Maybe some little core memory? i see some copper wires starting outside the box and the flatpacks near to this give the feeling of this ...

thnx for looking and for your Time-Ideas

This is a strange board indeed. Looks like an early bubble memory
to me with read/write amps in the small ceramic chips and two coils
(see the four thick copper wires) for the X- and Y-deflection! Would
be awesome! Anyway a very obscure board and great find!

Nice board! I could also be a ferrite core memory.

Is it possible to open the module without damaging it? Perhaps you could try to do an X-ray photograph - if you have somebody with access to such equipment.

well ....the box is hermetic closed As i we see with some kind of strong glue....Around the edges As u see in the 3rd picture....
propably will brake i if i try to open ..im not want something like this.....

As for the X-ray good ideA ......BUT no Access to this Equipment ...

Airports, post offices, access control to official buildings ... they use the equipment. Maybe you have some friend who works at one of those places.

well....i have some Doctor friend's ......may i use some X-ray machine ....but i think themachine must be re-Adjusted to Make a clear imgein this scale.....nd with All this Metal Layers ......May need ovr one hour to Adjust the machine And One hour to Brigback to Human x-Ray settings....... this is time-Money Cost to the Hospital .....
if finally take some pics ill Update the Post for Sure..

A few years ago I worked with a Heimann scanner identical to that used in airports. The pictures only will allow you to see shapes and type of material (plastic or metal) but at least you can know if there are chips inside and the size and shape of these.
It is very possible that in Police Stations have these scanners. You can try and not cost you money.

A plain X-ray may give you a pretty good idea. If there are little ferrite cores (used in Core Memory) in there, they would absorb X-rays much more than the plastic / epoxy enclosure and show up easily. And the package seems reasonably thin so you should get away with a regular x-ray machine (that's used to take body xrays).

Hello,
VERY nice and interesting board. Great! IMHO it's a core memory card (I see a wire that looks like a sense line coming out from the sealed block). The markings on the little daughtercard remember me the "Ampex style".
Core memories have been used in aerospace applications for many years, well after the introduction of solid-state RAMs and EEPROMs, because they were less sensibile to EMP (ElectroMagnetic Pulses) and other interferences.
