What kind of RGB monitors will work with a IIc and a Laser 128?
I don’t know about the Laser. The IIc doesn’t have built-in RGB output. Its video port provides several low-level timing signals which allow RGB data to be decoded from the composite video signal (which is also provided on the port), but this requires external hardware. The “standard” IIc RGB adapter (assuming there was one) would probably have produced digital RGB output, the same as the Apple III and the Apple IIe memory expansion cards with RGB output. With a digital RGB monitor, standard digital logic levels (TTL) indicate whether a colour (or colour weighting) is present or absent. One wire is required for each bit of each primary colour. The IIgs, on the other hand, produces an analog RGB signal – a voltage on the Red, Green and Blue outputs represents the intensity of each primary colour. Any number of shades of each colour can be supported, by providing a finer resolution digital to analog converter within the computer. The IIgs has 4-bit D-to-A for each primary colour. High-en
