[GreenKeys] French barn find

[Thierry Stora]

Hi fellows vintage technologies addicts,

being many things but not a novice in restoration and collecting of 
electronic and electro-mechanical devices such as boatanchors, test 
equipment, pre-eighties computer systems and peripherals, a dozen of 
pinball machines, ..., I've had the opportunity to put my hands on an 
unknown (by me) teletype / tape reader and puncher set.

It's branded by SAGEM, a company that many know today for other activities.

I had already seen a "fully electronic" model of Sagem teletype of the 
end of the seventies which included a crt display and a printer but 
never anything like this before.

Some (very poor quality) photos:

Of course I've Googled it, without any sucess.

Willing to restore it to working condition to hook it to my Motorola 
Exorciser clone of the seventies I would be glad to get as much 
technical information on it as possible.

Maybe this particular tty says something to someone here, or maybe the 
mechanical part is a licensed copy of an American system as this kind of 
technology transfer was common in those times.... I sincerely hope so, 
as it could be an easy way to have some data about the adjustments / 
mechanical settings.

So does it looks (at least its mechanical parts) visually familiar to 
the experts around?

The teletype / keyboard part seems to be a rather ancient design, it's 
of the fully E.M. kind. A gearbox located close to the front left of the 
machine and driven by a motor located behind the paper tray seems to 
power the whole thing.

A lot of state display lights/ function keys are visible on the front 
panel. They suggest (their naming) that some kind of communication stuff 
is embedded in the beast.

A quick spin around it shown three large dual-sided printed circuit 
boards populated with a mix of standard TTL chips plus apparently some 
linear I.Cs. and discrete components stacked in the base of the machine, 
under the typing unit.

It seems to be in very good condition and absolutely complete (with the 
exception of 1 key cap and the usual absence of the drawer collecting 
the confetti from the puncher) and untouched, but extremely dirty as all 
true barn found items are. It will need a complete strip down to be 
cleaned correctly and restored to working condition, which is the golal. 
This has been worsened by the removal of the keyboard cover during a 
long period (I put it back before to take the photos).

If unfortunately I can't get any help / documentation I'll of course 
however restore it, but... I'm sure that everybody here understand my 
thoughts.

Thanks for looking to this, and by advance many thanks for any comment 
on this Sagem. I'll not start to work on it quickly as the bench is 
already crowded by other works in progress which must be completed 
first, especially my beloved RCA AR88. I plan to put some pages online 
about the restoration when I'll have started to work on it, a job for 
the next winter I think and hope.

Hope also that I've not bothered too much people with this tale.
