[GreenKeys] Hoping someone can identify this paper tape punch (UJI-400)

[Gary Oliver]

This thing followed me home a few years go...  I am in the process of 
decoding the connections, but decided some of you might actually know 
what this is and if there is a manual available somewhere. I've searched 
but to no avail.

It's a UJI-400 Tape Perforation, an 8 level machine.  The company, 
'Seiscor,' suggests some connection with geological exploration (they 
are/were a seismological instrumentation firm, I believe connected to 
oil and gas exploration.)  Google has turned up nothing useful so far.

What seems unusual to me is what appears to be a 'diode rom' and reader 
built in.  It contains a stepping relay with about 25 contacts that 
sequentially access the contents of the diode board (big board on left 
side of reader in photo #2.)  I've attempted to decode the diode array 
for any identification, but I cannot make sense of the contents - if 
ASCII or EBCDIC, it's random to me.

A link to the photos can be found in my 'Dropbox' at

You do not need a Dropbox account to access this.  Just open the link in 
your browser and you should see the files.

I'll gladly send along pictures to anyone that cannot access the above link.

Thanks,
