Hi,

apart from the standard MARK 3A US Navy plotting board and the E6B types, what computers were used by USN aircrew during WW2?

Was the MARK 8 ‘prayer wheel’ used during the war or was it post was issue?

 

I have the black AN5835-1 type marked US NAVY and a round MARK 8 (but it looks too modern), I almost purchased an older MARK 8 made from what looked like cardboard of some sort but wasn’t sure what era it was.

thanks in advance for your help,

 

cheers, John

From what I remember the Mark 8-a was also used in WW2 Mark 3a and 5a plotting board, It should have a contract. But this is a integrated part of the board. The separately Mark 8-a computer is useless I guess...

 

Here is a photo of Mark 8-a computer on Mark 3a plotting board: http://www.usmilitar...ttach_id=777991

Thanks,
I forgot that the MARK 8A was used on the plotting board.
I wonder what the earliest MARK 8 not mounted on the plotting board was.
Cheers, John

I checked my MK3a board and it got a Mark 8 computer attached. But saw a example with Mark 8-a also.

 

Im not if they used a separately Mark 8 or Mark 8a computer? Maybe in a multi-engines aircraft, for sure not in the single engine aircraft!

 

Cheers,

Jerry

Hi,

I finally found the MARK 8 that I had seen on the net, seems to be made of card of some sort and quite old looking, the only MARK 8 I have seen not on a plotting board.....lots of later MARK 8A metal computers about, with and without the tabs around the edge.
