Sorry Tony,
I guess one passable reason is that I don't want to use 8k for a
monitor, although I could always program alternative monitors in 1 or 2k
segments and select with a switch.
So whilst 4 x 2716 chips are sufficient, allowing for spares etc, I
wasn't intending to use them all on the same board.

P.S. on checking on E-Bay UK 2764s seem quite expensive compared to
2732's...
I am
collecting bits to build a 6809 machine and I wanted some EPROMS
for the monitor. I found I found 4 x NECD2716Ds which I am sure these
will do fine for that. I and also I think they can be programmed in a
Willem.
Given that uyou only need an 8 bit databus on a 6809 system, is there a
goodreson not to use a 27(C)64 for the monitor? Point being that those
ave very easy to get, every programemr will supprot them and it's only
one 28 pin chip to wire up.
