; ; M7RA-1.ASM This overlay has been adapted for the Royal Alphatronic. ; The Royal uses a 8251-A USART which can be software defined except for ; baud rate which must be hardware selected inside the machine. ; ; Port 41H can be programmed with the proper mode and control commands. ; The chip select command is MVI A,0CH, the internal reset command is ; MVI A,40H, the mode command is MVI A,4EH for 8 data bits, no parity, 1 ; stop bit. The command instruction is MVI A,37H (all out MODCTL2) ; ; M7DP-1.ASM -- Datapoint 1560 overlay file for MDMxx2. 11/11/83 ; ; You will want to look this file over carefully.
