-
- 2013-12-01 Driver for Cromemco MCB-216 SCC (Single Card Computer),
- and also the earlier CB-308.
-
- The driver is working, just missing some hardware info (see ToDo).
-
- TODO:
- - Find out cpu clock speed
- - Find out what UART type is used
-
- Memory allocation
- - 0000 to 0FFF - standard roms
- - 1000 to 1FFF - optional roms or ram (expect roms)
- - 2000 to 23FF - standard ram
- - 2400 to FFFF - optional whatever the user wants (expect ram)
-
- MCB-216:
- Press Enter twice. You will see the Basic OK prompt. To get into the
- monitor, use the QUIT command, and to return use the B command.
-
- The mcb216 can use an optional floppy-disk-drive unit. The only other
- storage is paper-tape, which is expected to be attached to the terminal.
-
- CB-308:
- Press Enter twice. You will see the Monitor logo. To get into the BASIC,
- enter GE400. To return to the monitor, use the QUIT command followed by
- pressing Enter twice. All monitor commands must be in uppercase. The
- only storage is paper-tape.
