One is already reserved for you.
How many more do you want?
I have PCBs only for further 4pcs.

Received, but I burned it! 
works perfectly with all my NSC800 but after I try a military chip it stopped to work
8080 board and other two expansions still work perfectly
may be it's the rom?
... but it's better if I order another board, I'll take it with the next your project.
another question: there is the manual for this NSC800 expansion?
thanks! |

Maybe the PLA went wrong. That can be changed. It's worth a try. I'll send a replacement to you.
The address latch can be wrong too, but that's more difficult to change.
Do the studs of the ZIF socket look good?
Unfortunately, there isn't manual for NSC800 expansion yet.
It can be used similar to other expansions, except that the CPU external clock can be selected by the jumper.
Default is 2.2MHz and can be slow down to 1.1MHz for slow CPU that does not support internal clock higher than 1MHz. Note that the external clock is divided by two by the CPU for internal clock.
