MS/PCDOS v1 did not have any hard disk support at all. This came with the XT
and v2.0. The diskettes that v1.x cane on were 160k single sided floppies.
There were only 64 entries in the directory. You are thinking of v2.0.

Same here. I got the Microsoft card and had SuperCalc, Word Star, and dbase
II. I am still lokking for an Mbasic compiler converter to Quick Basic. I
have some old programs written in Mbasic that I would like to convert.
I am also looking for a program that will read APPLE ][ DOS 3.xx on an IBM
PC. Everyone says it cannot be done, but I know that it can. I could copy
APPLE ][ diskettes with my IBM PC using the Central Point Deluxe Option
Board. But I cannot just transfer the files for use in an APPLE ][ emulator.
