Vernon B. Hester, author of MultiDOS and other wonderful programs, has provided some additional copies of his DOS’s:

Esoteric DOS v2.11 for Model 4
MultiDOS v4.01 for Model I
MultiDOS v4.01 for Model III
MultiDOS v5.11 for Model 4

ESOTERIC is a Model 4 version of MULTIDOS with two differences: Video (Esoteric is 80×24 vs. MultiDOS which is either 80×24 or 64×16) and ESOTERIC is mapped significantly different than Model 4 MULTIDOS. The mapping of the Model 4 is very similar to the Model I, Model III, and MAX-80 version of MULTIDOS, while ESOTERIC’s mapping difference was desired to keep the DOS in contiguous memory (0000H through 1AFFH) allowing one to ORG applications at 1B00H.
