The VDA2001 is a full length Zorro II digitizer. The only connector on the back is a female 25pin Sub-D connector. The card also contains a potentiometer, probably to help fine tune the image quality. The VDA 2001 was supplied with an additional component which had FBAS and Y/C video connectors. Without this external unit, the card is completely useless. It uses a Texas Instruments 34061 chipset with 1MB of RAM and is capable of capturing at up to 512 x 580 in 24bit.
