ripsaw8080 and I were having a discussion about another issue and he mentioned that in DOSBox 0.74, the base amount of free RAM in the Tandy machine type (conventional memory - the amount used by the video buffer) was 608KB. In DOSBox SVN, the base amount of RAM is 624KB. This change fixed several games and reflects the default base RAM available in a 640KB Tandy 1000. Unfortunately, one game it breaks is Might and Magic III with its Tandy graphics mode. MM3 refuses to work on a real Tandy with the Tandy graphics mode selected and 640KB of base memory. Increasing the RAM in the real Tandy to 768KB allows the game to work. The extra RAM is used solely for video and there will be 640KB base memory available. Apparently MM3 requires the base memory to be a multiple of 32KB. As the color is the same with the EGA mode, which has no such difficulties, this is more of a note for any future compatibility issues.
