M868 simple
dectape control $100.00 plus shipping 
 The infamous TD8-E.  Don't use this unless you can't get a "real"
 DECtape control, which would be a TC01 or TC08.  Of course, for use
 on an Omnibus PDP-8 (8/e, 8/f, 8/m, 8/a), those also require the
 positive I/O bus interface, data break interface, and possibly a
 negative bus converter.  So on second thought, if you have an
 Omnibus 8, maybe the TD8-E isn't so bad.
  M8650 console interface $100.00 plus shipping
 Seems rather pricey to me.  Now if I could get the M8655 for this price...
