VFD interface circuits

[star882]

I want to install a VFD in my old PC.
I will connect the tube filament to 3.3v through a diode(the normal voltage is 3v, the diode trick gives 2.6v, which is close enough).
The serial connector on my PC's motherboard provides a way to control it with software.
I can use 12v to drive the grids and anodes(a PNP transistor, a NPN transistor, and 4 resistors makes a simple driver).
Does anyone have a way to do this?
Any schematics and block diagrams are helpful.
Of course, I know there are some store bought displays, but at $100 for one of these, I would rather buy a fast cd burner.

I was thinking about using a microcontroller from radio shack to translate the serial signals to the VFD signals.
How do use a microcontroller?

"How do use a microcontroller?"

Simply write the operating system/application, then program the uP, or an eeprom, if the uP doesn't have any on board.
I'd use a development system to save time though.
What uP are you using?

I will use an AT90S8515 Flash Microcontroller from radio shack.
By the way, once I get it working, I will put the program for the microcontroller and the display daemon(a daemon is a windows background task) on my website.
Here is the price for parts.
MCU:$9.99
VFD:unknown as I found the one I want to use for free in a parts box.
diode:$0.59
driver circuit:$7 for 20 channel driver using LM324s
RS232 driver:$1.55
PCB:$3.99

I have Futaba VFD code for the 8515.
The displays I have are two line, clocked serial interface. Very nice appearance.

Radio Shack is selling AVRS?
