- This is not the forum for describing specifics about interface designs. Plenty
- of RS-232 interface designs using the Maxim chips have made the rounds. If you
- need step-by-step innstructions, perhaps someone can point you to a file
- available for FTP.
-
- I gave you the source of the chips: Maxim. The orignal was the MAX232 and
- there have been several later ones that even further reduce the need for
- external capacitors and/or include more than the original two drivers and two
- receivers. Their 1993 catalog (last one I have, sorry) is an inch think -- a
- little much to duplicate here. Give them a call at (408) 737-7600 and ask for
- a catalog. (Mine even has free-sample request cards!) Or visit their web site
- at http://www.maxim-ic.com/index.html.
-
- It is your dealer I was considering misinformed. If he really thinks this
- stuff is NEW, he is NOT someone you want to trust to make you an interface. I
- realize many users don't keep up, but a dealer should do better. Nobody uses
- 1488 and 1489 chips for RS-232 interfaces anymore unless they already have the
- +/- 12VDC available (which the C-64 does not).
