Volume 1 -- Issue 7            April, 1981


As of today the total distribution of the Apple Assembly Line is nearly 350.  Let's shoot for 1000 by the end of 1981!  I will have a full page ad in the next eight issues of NIBBLE, so I think 1000 is a reasonable goal.  Thank you for your support!

Cross Reference (XREF) for S-C ASSEMBLER II

Bob Kovacs has a new product, one which many of you have asked me for.  It enables you to produce a complete cross reference listing of all symbols used in an assembly language program.  See his ad on page 7 for a description and ordering information. 

I am honored to have three companies (Rak-Ware, Decision Systems, and Flatland Software) producing software to complement my assembler!


80 Columns on Your Printer

For some reason unknown to me Apple's Parallel Interface Card comes with at least three different ROM's.  There seems to me no indication on the package which one you are getting, and no listing in the manual of the exact ROM on the board.  This leads to confusion, because some ROM versions will print 80-column assembly listings at the drop of a hat (Just type PR#1 and ASM, and you have it!); but others require you special treatment.

If you have the latter type, I have found that this works:

     :PR#1        (assuming slot # 1)
     :$579:50     ($578 + slot#     )
     :ASM
