Hi Tony,
You could find the NEC FIP16A5R datasheet for this component?. If yes,
please can you send by e-mail this datasheet. Also I will like to buy 2 or
3 FIP16A5R. Can you tell me where I can find this one?.
Best regards,
Brice.

Near to the Nec FIP display in the Newbrain computer there is a little
circuit with a componet with 10 pins where you can read:
27
CD-1867N
TDK
JAPAN
I haev the official Newbrain scheamtics here....
That component is probably a transformer. The module it's part of is a
DC-DC converter to run the display. It has, apparently, 7 connections :
1) +5V input
2, 5) linked together, seem to be a -ve output (22uF to ground
3) Output,also -ve (22uF togoround, also goes to Vbb on the DS8881, and
the pull-downs on the segment (anode) leads)
4,6 ) Heater outputs to the display
Somebody know what is this component? I think it is used to control
voltage
supplied to de display.
Somebody have the NEC FIP16A5R datasheet? It is the 16 character display
in
the Newbrain AD
I can at least tell you :
Heater : 1,37
Grids (digit select) : 3,5,7,9,14,16,18,20,22,24,27,29,31,33,35
Anodes (segments) : 4,6,8,10,13,15,17,21,23,25,28,30,32,34
