Workbench 2.1 Upgrade Notes
The AmigaOS 2.1 package was only available as an upgrade. It
differs from almost every other version by consisting only of the
Workbench disks. It still used the Kickstart 2.04/2.05 ROM found in
the A500+ and A600. This means that it is a very simple to install
with no fiddly ROM chips to stick in your machine or software
incompatibilities with 2.04 software.
ECS features
The ECS was a second-generation custom Amiga chipset. It was a vast
improvement over the OCS (Original Chipset) by increasing the
amount of chip memory that could be accessed to two megabytes and
could handle a greater variety of resolutions. ECS can be found in
the A3000, A500+, and A600. The Enhanced Chip Set was required to
use these functions.
- 640x480 non-interlaced Productivity Mode (requires 31
kHz-capable monitor)
- 1280x200 and 1280x400 Super-hires Modes
