reference the to first location of the EPROM.
I think a 2716 is a 2K EPROM (8 x 2 = 16 hence 2716), 2K = $0000 thru $07FF
: +-> ERPOM Sits here ($0000 - $07FF offset $E000)
$0000 - $FFFF 64K address space of the Z80/8080/8085 processor

Thanks. I have among other projects been working to use a North* MDS
controller operate within an Altair system. I also have a working
Northstar Horizon system that runs N* and N* CP/M. On my Altair I am
using a 2SIO card. I have found indirect docs on how to personalize
N* DOS for the Altair 2SIO card, but so far I have not been able to
make it work. Any details of your version of N* DOS would be useful,
and/or a few representative disks.
If you were looking for a home for some of/all of the disks, I would
work with our club members to get CBBS running again.
