The computer represents a modernized and significantly simplified version of the original TEXT01. From the original model, the TEXT01.M1 retains only the grid (backplane) for the PCB and the PCB bus, while the other PCBs have been redesigned to remove everything superfluous for its operation.
It is a closed system that does not allow adding additional PCBs to expand functions.
Unlike its predecessor, the TEXT01.M1 uses an FDD controller with 8272 and 8257 circuits
The system from TEXT01 cannot be used on TEXT01.M1.
