Bookmark or Share- How big is the screen of the Amstrad CPC 464?The Amstrad CPC 464, released in 1984, was distinctive for, among other things, being the first UK home computer to have a built-in monitor instead of assuming you would use a TV set. How big was the
- Why did the Amstrad CPC use a nonlinear screen memory layout?least significant bit: an internally generated left/right bit, as Amstrad fetches two bytes per CRTC address. So it’s linear across a line, for all supported line lengths (and then some). With a 6845 it is impossible to have a fully linear display unless you can fit the entire buffer with 14 bits of address space.
- Can I connect a Sega Megadrive or Genesis to an Amstrad Cpc monitor ...I have a suspicion that amstrad monitors require the amplitude of R/G/B signals to be significantly more than standard 1.0v peak-to-peak. At least, I've heard complaints from a person who've connected his ZX Spectrum 128k's RGB output to such monitor, that the picture was too much faded.
- Is it possible to use an Amstrad CPC464 with a modern monitor or TVYes, it is possible. There are a number of ways: If your TV has a SCART connector, you need a cable adapter from DIN 6 to SCART, wired like this (the audio is taken from the audio out using a standard stereo 3.5'' jack):
- How long are interrupt requests remembered on the Amstrad CPC?In the CPC the Gate Array generates maskable interrupts, to do this it uses the HSYNC and VSYNC signals from the CRTC, a 6-bit internal counter and monitors the interrupt acknowledge from the Z80. When [counter conditions are met] the Gate-Array will issue a interrupt request to the Z80, the interrupt request remains active until the Z80 ...
