 # tranz330_re
 Partial reverse engineering of an old Z80-based card terminal
+
+This repo is for a reverse engineered schematic and other
+stuff that might be helpful for developing replacement software
+for the Verifone Tranz 330 credit card terminal.
+
+The Tranz 330 has a Z80 microprocessor at its heart and uses
+design conventions and peripherals often found in Z80 based
+computers.  Although it's compact, it has a socketed EPROM and
+DIP packaged components for all but a few logic ICs, making it
+easy to work on.  And since they do not have the security
+features needed for modern credit card processing bureaus, they
+are available cheaply on the used market.
+
+The schematic here is a work in progress.  The logic on the
+mainboard is almost fully mapped.  
+
+I don't plan to map the power supply, modem analog
+section, or all of the logically superfluous discretes (bypass
+caps, battery backup, etc).  At some point I'll make a logical
+schematic of the VFD / keypad board.  I want to end up with a
+reference that's useful for writing software and tacking on
+hardware.
+
+If you want to get started writing for the Tranz 330 now, check out
+Big Mess O' Wires work at
