same as a 16 pin IC). Meanwhile the CPU board
keyboard connector (and
corresponding schematic) is numbered in a more conventional pattern with
odd pins on one side and even on the other.
I thought IC connections were always numbered down one side then back up
the other one? I've not seen any that are numbered across the chip?
Yes, but header plugs rarely are.
IC :
1 16
2 15
3 14

8 9
Header
1 2
3 4
5 6

15 16
Well the Nascom 2 keyboard seems to be very
similar to the Nascom 1,
except that (as others have noted) it has an extra scan row so uses 7
data bits rather than 6.
I can scan the relevant pages in the hardware manual; I've got the full
Does your Nascom 2 manual contain a keyboard schemmatic? I thought mine
was complete, but that's one thing that's definitely missing. I do have
scheamtics for the mainboard, 16K RAM board, 3A PSU, 3rd party EPROM
programmer, etc.
