N* BASIC running on CP/M. It's been done already by InfoSoft Systems
in 1981. I found it on a Lifeboat CP/M disk I downloaded from the
web. The file is NS5BAS.COM. It says "N* Basic revision 5.2 for CP/M
By InfoSoft" when run. Also included on the same disk is a program
to copy N* basic programs from an N* disk to a CP/M disk. That file
is called NSDD.COM. It says "N*DOS -> CP/M File Transfer (NSDD
01.00) (c) 1981 InfoSoft Systems" when run. I have used both
programs and they seem to work fine.

I have been going through the disk images I have downloaded from the
web and found Mbasic ver 4.51 and Mbasic 5.1. I copied them to a new
disk image. Mbasic 5.1 I renamed Mbasic5 because I wanted both
versions on the same disk and both files were named MBASIC.COM. I
think mbasic 5.1 is the same as Basic-80. Not sure though. Mbasic
4.51 is the same or very close to Altair Disk BASIC. I run a copy of
Star Trek written for the Altair on it. This version of star trek
will not work on Mbasic 5.1 without modification. I can't remember
exactly which disks I found these programs on. I would copy them as
I found them to my own disks. I can post a disk image with the files
on it if anyone would like them. So you don't need to go looking for
them. Everything on the image is already on disks available on the
net. Nothing is new except Altair Star Trek and even that is
available with the Altair simulator.
