[GreenKeys] KS7470 oil

[COURYHOUSE at aol.com]

Right on Doug!
you  have  managed to solve the riddle of the   'match'  to the classic  
old  oil it   seems!
seems like a good  project for Don's  group to buy the 5  gallon  pail ?
 
A nice  Teletype repairman   that  fixed us up   with  zillions of keyboard 
and printer springs and tools and the magic  gold oil can  told me about 
adding STP  to  the stock oil.
 
Would  anyone   comment on the 'science' behind  why  and  if there  is any 
detriment to the STP? 
<aside  from  wanting to stick racing decals on  your  28>
 
The oil question was  appearing so much I always thought it might be  good 
to add the solve to the signmature block for the  list

Climbing  around on the web, I have found the specs for KS7470 oil,
and I have found  the specs for a number of other oils with which
to compare it.

The  results of my exploration are here
--  http://www.cs.uiowa.edu/~jones/pdp8/UI-8/ks7470oil.shtml

In conclusion,  Starrett 1620 Tool and Instrument oil is almost
certainly the exact same  thing.  $6.94 per 4oz. bottle

Several other highly refined white  mineral oils are every close
matches.  Lubriplate FMO-AW 200, for  example, is available for
about $139 for 5 gallons or $1,466.38 for a 55  gallon drum.
bulk discounts are nice, but I don't need that  much.
