According to the _Microcomputer Buyers Guide_ (c) 1984, Byte books: "NNC offers two systems - the 80 and 80W. Basic features of the model 80 are: Z-80A processor (4MHz); 64kB RAM memory; two RS-232-C serial ports; three 8-bit parallel ports; and two Shugart 801R 8" floppy disks. The 80W offers different storage capability with one 8" floppy disk combined with one 8.4MB Winchester hard disk. The basic Model 80 and Model 80W systems are single-user in operation but can be expanded with additional terminals and printers for up to six users. A maximum of 256kb RAM memory is accomodated." The entry goes on to say that it came with CP/M standard, but you could also get OASIS from Phase One Systems "for multiuser applications". The listed address (for what it's worth) for NNC is: NNC Electronics, 15631 Computer Lane Huntington Beach, CA. 92649 Sounds like a pretty stock CP/M machine, typical of the era . . . Jeff

Marvin, I believe the 1st edition was released in 1981. The one I have is dated 1983. I Also have an 'update' dated May, 1993. I'm not sure if any subsequent updates were published. I have had these books for probly 10 or more years, and I used to take it with me when 'On the hunt'. Oh yes, it does have pictures, although they're not always accurate. It has lots of good information on machines of the era. Jeff P.S. I'd probly commit a murder for a 1st edition };^) (I've never actually seen one, though).
