 I think they came from ITT 3287 terminals (or ITT Courier, or Courier
 Terminal Systems). I have several boards from those terminals (all
 from around 1976-77), they used the i8008 as processor (see picture).
 The unknown AMI IC is found on a board labelled CURSOR/BUFFER. I have
 boards with that IC as only LSI chip, or along with a Signetics 2650. 
A 2650 is a microprocessor.  I don't recognise the 1315.  Henk's
recollection of the AY-xxxx UART may be a little off, I think -- I
believe he's thinking of an AY-3-1015 or AY-5-1013, both of which are
UARTs very like the standard Intersil 6402 UART (in fact the 6402 is
almost identical, but with slightly different electrical
characteristics).  The AY- series were made by General Instrument
Corporation and included things like keyboard encoders, UARTs, sound
generators, etc.

...
  So my question is, what is that AMI chip? Has anyone a
datasheet?
 Oh, and I have some NatSemi 1409, 40 pins, as found on the TIMING
 board (which also contains 16 i1404 1kBit MOS shift registers as display
...
  memory), what is that? 
Dunno about that either, sorry.
