CP 450 was a large cabinet containing a floppy disk drive interface for the CP 400, manufactured by Prológica, a computer company located in Brazil.[1][2]
General information
The device was similar to those used by the TRS-80 Color Computer.
The standard operating system is DOS-400,[3] an adapted and renamed copy of disk Extended Color BASIC (DECB or RSDOS). It was also possible to run other operating systems, such as Microware OS-09 and TSC Flex9.[2] Using OS-9 allowed the user to access all 64 KB of RAM available on this particular version of the CP 400.[2]
It used 5¼-inch single sided floppy discs capable of storing around 218 KB.[3]
The CP 450 units stopped being manufactured at the end of 1986, along with other accessories suitable for the CP 400.
