| Configurations | It can't be used without a ROM Cartridge. Some sources says that they don't have RAM installed and other sources says that they has 2KB, others 18KB,.... Finally, I find a schematich diagram, and the RAM installed on the motherboard are 2KB. The total RAM amount depend of the BASIC cartridge used. In the list of Sega released cartridges appears 5 BASIC cartridges, although I only have find information about three BASIC cartridges:
BASIC Level IIB: without info. BASIC Level IIIA: 32KB of ROM with the Sega BASIC and 16KB of RAM. BASIC Level IIIB: 32KB of ROM with the Sega BASIC and 32KB of RAM. BASIC SK-III: without info. It appears be the BASIC for the SK-1100 keyboard add-on for the SG-1000/SG-1000 II consolle. Also exist a add-on which adds a 3" floppy disk drive, 64KB of RAM, 8KB of ROM (with the Disk Operating System), a serial RS-232 port, and a parallel Centronics port: the Sega SF-7000. Also include a DISK BASIC floppy. |
