  It's a standalone device.  Well, aside from a terminal. :)  That's  
the main reason I love these Data I/O UniFamily programmers (UniSite,  
2900, 3900, etc).  Also, no PC-proprietary parallel ports...100%  
standard RS232 serial I/O.  You could run this thing from a PDP-11 if  
you wanted to.  Windows is persona non grata here, and I'm certainly  
not going to depend on it for something critical to my work like  
controlling a device programmer.

  You just connect an ASCII ANSI terminal (I use a VT420) or a  
computer running a terminal emulator and interact with it directly.   
The user interface is very good, fast, and easy to use.  If you  
really want to, it does have a mode that you can set which makes it  
communicate using a remote control protocol over the serial port, and  
Data I/O has software for Windows which can control the unit via that  
protocol.

  The 2900 has a floppy drive from which it boots and loads  
programming algorithms when you select a device.  The later models,  
including the UniSite, optionally have a hard drive which stores all  
of that.  My recently-acquired UniSite has a hard drive and two  
floppy drives.  They all read and write FAT-formatted floppies.

  I really can't recommend them highly enough.  I've used a bunch of  
programming systems, and these are, by far, the best I've ever seen  
in every regard.

          -Dave
