Ok, everyone, do you think it would be possible to control a basic VGA CRT computer monitor using a BASIC Stamp 2's outputs? If so, do you have any advice for me?

The short answer is no, absolutely not. A Basic Stamp is simply not fast enough to do anything like this. Even if it were fast enough, it doesn't have enough memory available to have something to display on the screen.

The closest thing is the Propeller which works very well with a VGA CRT, can display text and some graphics (limited by available memory), but it has 32K of memory including a 32K ROM with a text font included in it and runs at an 80MHz system clock. It has 8 identical processors on the chip and 2 of them are needed to produce the VGA output along with another for the main program.

For $40, you can get a Propeller Protoboard with the Accessory Kit, do a little soldering, download the manual and Propeller Tool, and have a VGA display device that you could use by itself or plug in a BS2 and use the Propeller as a VGA terminal for the Stamp.

Nice serial-command driven VGA video card.· Has some sample BS2 code on the website.
