Anyone know more about this? So far I have only found references to Rayethon Computers in
old trade mags.

The rack is as stout as it gets.
BTW if anyone wants a nice RXO2 (auction ending in 6 hours), bidding starts at $1:

Hi Justin,
I could use another RX02. I know someone going to Denver for the DG event.
Anyway you could get it up there? What do you think shipping would be to
IL? I'd put $50 into it and another $50 into shipping.
Thanks, Paul

Hi Paul, shipping is automatically calculated by ebay, there should be a
small calculator icon by the shipping info on that listing. Since it's
up for auction, I cant gurantee you will win, but best of luck! I am
happy to ship to any address the winner provides, and I take great care
to pack things properly.

It looks like a Raytheon 706 without the front covers.

A complete general-purpose system complete with asr33 and XRAY compatible
papertapes would be awesome and pretty rare. Are there any complete 706 or
703s out there I wonder.

These are all pretty boring--8-bit multiple word size, etc.
How about some 22-bit or 13 bit architectures?

Nicolet 1080 is 20 bit data but has 16 bit address space. No stack functions. It has a
register called link but that is only a single bit carry. Subroutines use the first
address to store the return, meaning they were not recursive without something to save the
returns ( I think dec did this too but I'm not a dec person ).
20 bits was considered enough noise level to do ffts for NMR chemical analysis. The
machine typically came with 12Kx20 core but one could add on another 12Kx20 unit, even
though the address size could access 64K. There were special DMA operations that only ran
on the lower memory.

While we're throwing around bits, here's one - the 1960 ISI 609 Information
and Computer System runs
4096 Words of 39 bits plus a parity bit
OR
8192 Words of 19 bits plus a parity bit
OR
12288 Words of 13 bits each.
...but the basic machine operates upon 39 bit words with the instructions.
The 19 bit is for progrmmed features and the 13-bit word is used to store
data constants. ISI Information Systems was out of Skokie Illinois, they
used to be called Panascan Division Panellit, Inc.

Aw, come on, you could know it better. We also have a 704 since many
years, including software and documentation. You have mirrored my scans

I have a copy of the February 1970 Raytheon 706 Computer User's Manual.
Basically it's a 16-bit mini computer. The system monitor is a program
called X-RAY (theon) and the 706 was paired with an ASR 33.

AN/FYK means fixed installation, data processing, computing,
which doesn't tell a whole lot.
I couldn't get any hits on the FYK-9.
In the contract number, it indicates the contract was let in
1967. I see IC's on the boards and what looks like a core
plane in the middle. In fact, from the card type
designators, I'm guessing that module at the top is JUST a
core memory system. It is also possible the core memory has
nothing at all to do with the label on the rack, and was
just swapped into the rack for storage.
The core memory system seems to be made by Data Products /
Cambridge Memories Inc.

Thanks everyone.
Here is a pic of the back: http://v6y.net/IMG_20180924_183318.jpg
I will keep my eyes out, there is a small chance I will find the computer this memory went
to.
The bottom item in the rack is also labeled Rayethon, it's a power supply.
