CQV1 Real Time Digitizer – A Review

The CQVI video digitizer package consists of the CQV1 hardware, a 3.5″ disk and an 8 page manual. The CQV1 electronics are installed in a black plastic case, measuring 7″(18cm)x4-1/4″ (11cm)x2″(5.5cm). A male edge connector extends out of the front of the case to mate with the ROM Port at the rear of the QL. On the opposite side of the case is a black control shaft for black-level adjustment and next to the control is a phono jack for video input. There are four plastic feet secured to the bottom of the case which levels the digitizer at the approximate height to mate with a OL resting flat on a desk. I found this arrangement awkward for my purposes as my QL is installed in a PC XT case and it was difficult to perform black-level adjustments when nec eQVi now rests upside down on top of the XT case, providing ready access to the black-level control. I installed a small knob to the shaft of the black-level control, providing precise adjustment.
