The Barkovitch Utilities

Did you notice Dave Barkovitch's ad last month?  He has written a very handy set of utilities for us serious Applers, and sells 'em cheap!  Be prepared to puzzle your way through his admittedly skimpy documentation, but it is all there.

The I/O Tracer comes in EPROM on a little card that plugs into any slot 1-7  for only $40.50 (including shipping).  I/O Tracer is essentially a powerful disk ZAP utility, allowing you to read/write/edit any DOS 3.3 sector.  You see an entire sector at once on the screen, in either hex or ASCII, along with all status information.

Dave's Single-Step Trace program will help you debug assembly language.  He likes it better than the other commercial varieties of debuggers, and sells it for only $35.

Any questions, call Dave at (201) 499-0636.
