This is a Dell Optiplex 330. It has a new solid state power supply, 1TB hard drive, running Windows XP. I used this for 12 years to drive my JV3-130SP.
It worked perfect, never an issue, can't say that about the printer. The box is RasterLink 2, but the computer has the ultimate version upgrade of RasterLink Pro 3.
Selling just the computer and software with dongle and the power cord and cord that connects the PC to your JV3. (No monitor or keyboard)
If your looking at a used Mimaki JV3, this is plug and play for that printer.
