HP65 Vintage Calculator - First programmable in space

Recently I found this gem on local classifieds, it was advertised as dead, but in excellent condition :)
After I got it i recharged the batteries and she still worked!

Next I need to make a power supply for it and some PAC programmable magnetic cards.

Great site with emulator and some technical details. http://www.teenix.org/

 

Deckel FP2 Horizontal Spindle 1967

Three manuals three stories. I am writing this post to help me make sense of the the information I have at hand, and after reading up on practical machinist forums. There are various tidbits floating around but nothing concise. 

The German manual I have, resembling an old book depicts a spindle very similar in design and layout as seen in the English manual version from 1974. The 1974 manual describes a machine with single wheel speed and feed dials, and external motor. Where the other two manuals describe the two wheel machines with internal motors. However the older English Manual title page has the distinct 70's look seen on other NC Machines, and the font used looks modern compared to the German version. This makes me believe the German version describes the 60's models, the English version describes the early 70's models and the second English version describes later 70's models?

The main differences I can spot are what looks like a second set of needle roller bearings closer behind the first set on the older versions. The English 2 Wheel Manual with 70's font, actually describes these as "loosen 6 tighten 7 to adjust the front roller bearing" further the roller bearing clearance should be a maximum of  .0004"/.01mm. The clearance of the rear roller bearing, is determined by the dimensions of ring 9..." So in this version the needle bearings can be adjusted, implying them to run on tapered sections, which correlates with some information on practical machinist forums. The older German manual does not make reference to this, but the features exist on the drawing. What makes it more confusing is that 6,7 are referring to adjustment rings in the other two manuals, used for adjusting axial clearance on the spindle.

Now the question, what spindle does my FP2 have? The spindle, quill and head bear the engraving 137/137 A with -1.0, which was later 'erased'. This makes me think the parts where custom fit for each machine. With initial test results engraved on the parts, for easier fitting to final machines.

Are some spindles adjustable radially? or is this an error in the manual, introduced by translation/ draftsman in the middle?

Bearing grease to use original KLUBER ISOFLEX SUPER TEL or Franz Singer recommends LDS18

 

If you have more information on the spindle serial numbers, or spindle versions, please leave a comment.

The entire machine is marked with what looks like a smiley with long eyes  =) anybody know what this symbol represents?

-1.0 Engraved on side of slot, not sure what this means since it was erased afterwards
