Windows 3.1 enhanced mode support is wrong

The article claims:

With the exception of the RLX and RSX, the Tandy 1000 machines are XT-class machines, which cannot support extended memory despite some models using 80286 processors. The RLX is an oddity, as it is an XT-class machine that supports 384 KB of extended memory, and the RSX is a fully AT-class machine which can support up to 9 MB of extended memory.

and

Tandy 1000s can work with Windows 1.0, 2.0, and 3.0 but not 3.1, with the exception of the RLX which can run Windows 3.1 in Standard mode, and the RSX which fully supports Windows 3.1 in 386 Enhanced mode.

Windows 3.1 enhanced mode does require a 386 CPU. If the RSX is only AT compatible, like the above text claims, then it has an 80286 CPU and can therefore only run Windows 3.1 in standard mode. The situation is similar with the RLX. If the RLX is only an XT, as the article above claims, then it lacks the 80286 CPU to run Windows 3.1 in standard mode. Windows 3.1 requires at least a 286 for standard mode and a 386 for enhanced mode. The reason why this:

Tandy 1000s can work with Windows 1.0, 2.0, and 3.0 but not 3.1,

is correct for all other machines is. Because Windows 3.0 was the last version of Windows, that can also be run in Real Mode. An 8088 can only run Windows 3.0 in Real Mode, not in Standard Mode. And Windows 3.1 lacks the Real Mode support. 84.158.113.105 (talk) 04:49, 8 June 2024 (UTC)[reply]
