Indivision ECS V4 A600 Flickerfixer/Scandoubler

Description

Indivision ECS V4 A600 flickerfixer/scandoubler is the successor to the Indivision ECS V3 and is designed for Amiga A600 and requires an A603, A604 or A604n Memory Expansion is installed(*).

All screen modes are converted to frequencies of 60Hz or more (output optionally at 50Hz for compatible monitors), and the S-Hires mode of the ECS chipset is displayed in full resolution and colour depth.

Non-interlaced modes can be ‘downgraded’ with the built-in scanline emulation to achieve the retro feeling that your old 1084 monitor provided over 30 years ago. The effect can be carefully adjusted: Anything from a very soft scanline effect to almost black lines in every other line is possible. Scanline emulation has never been so precise on a flicker fixer before.

Indivision ECS V4 also has built-in Graffiti emulation. Software that makes use of the Graffiti modes can display 256 out of 4096 colours without HAM artefacts. In this 2024 version of the flickerfixer, we have added further heuristics to keep programs from switching to Graffiti mode when the running program isn’t a program that really targets the Graffiti hardware (false-positive avoidance).

An additional adapter for a CIA chip routes keyboard signals to the flicker fixer. This gives way for a huge practical improvement over previous versions of the flicker fixer: You can now make small adjustments to the output picture format, including positioning and resizing of the output picture without the need to load the configuration tool.

Important information

The graphical configuration tool requires Kickstart 2.0 or higher. If you have Kickstart 1.3, you will only be able to upload a configuration (created with a different computer) with a command line tool.

A603, A604 or A604n memory expansion is required for operation. If you only have an A603, you’ll have to remove the floppy drive. To avoid short circuits, the metal shield must either be cut or removed entirely (most Amiga 600 computers were delivered without the shield in the first place, so this is a minor issue). If you have an Apollo accelerator card, you will need an A604 or A604n as carrier card. The A603 will cause a mechanical conflict with the Apollo accelerator. With A604 or A604n, the bottom cover will have to be left open, otherwise the keyboard will not fit.

The however the Indivision ECS V4 at this time is not feature-complete, all new features will be rolled out via flash updates over time. All flash updates will be free. Please note that for using all planned/future features, you may need commercial software that’s separately available. For all current features, the product is self-contained.
