AH!  the  Honeywell 316 &  516 wish I had  saved  ours...  We need one  for 
a museum display..  ours were  partials  looked ok but  missing some  cards 
 I let my  friends over at California Department of water resources have 
them to use   for spare boards.  We supplied the  majority  of HP spares  to 
them.  Darn! I let them have my HP 2114  computers   too...  We  need   2114 
HP computer   for a  display too.

The Series 16 computers were originally designed by Computer Control  
Company, which was then bought by Honeywell in 1966

at the time of  mini computers there was a high  speed paper tape  
reader made by FACIT in SWEDEN
not photoelectic  or pin in hole device the reading was electrostatic  
by measurement  of capacity
between 8 sets of electrodes
driving the tape by a capstan  system the speed was 1000 characters per  
second.could aso be  switched for half speed
also it could read and stop before the next  character(that is stoping  
in less than 0.001second
as it was a  long time ago maybe this start stop possibility was only  
at half  speed
I used it for loading pogramm
s in a honeywell DDP416 16 bits  mini
FACIT also had a nice 150 character per second punch
so you could  read any tape black,white,oiled or not with no error

by the way the  fastest photoelectric reader was used during WW2 by the  
COLLOSSUS  conputer used to decode
secret transmision at bletchly-park   UK
running at least 5000 characters per second.

nice pieces of  equipment have also been made in europe my pet  
teleprinter i the  T68d by Siemens which could punch and pint on two
different tapes  or  punch and print on 11/16 inch between the feed holes

very few OM's use  teleprinters now but for me it is a lot more   
interesting to  make a small QSO using my small Siemens
