[net.micro] VIC-1525 printer interface to Macintosh

len@qumix.UUCP (Leonard Labar) (11/03/84)

Does anyone out there know how to interface a VIC-1525 printer to the
Macintosh?  This is a dot matrix printer from commodore and it uses a
non-standard serial type interface.  It connects to a 6522 and has
these signals:
     pin 1  serial srq in
     pin 2  ground
     pin 3  serial atn in  (host signals)
     pin 4  serial clk out/
     pin 5  serial data out/
     pin 6  reset/

Since I already have this printer and $500 is a bit steep for an
imagewriter, I will be eternally grateful if anyone can help.  I assume
that I may need a software driver once I get this figured out.  To my
knowledge the only commercial interface is FROM the CBM host TO an
imagewriter.
