The Casio FP-1000 and FP-1100 were essentially the same machine, except that the 1100 had colour capabilities, 48 KB VRAM and enhanced graphic mode (640 x 400).

The FP-1100 came with either a monochrome (green) monitor which would display colour as shades, or the colour monitor. The cable feeding the video to the monitor was a simple 2 core unsheilded RCA cable. The mono minitor had a switch at the back so that one could swap foreground and background (green on black or black on green)

Both the FP-1000 and FP-1100 had a built in OS called C82 BASIC. To run CP/M, you had to insert your systems diskette and reboot the computer, or if the program diskette had it's own boot strap, you could issue a "mount \[1,2\]" command where the number \[1/2\] indicated the diskette drive you wanted to use.

You could run multiple console sessions on the FP-1000/1100 toggling between them with the blue function keyboard keys that can be seen on the image. Some programs (eg SuperCalc) ussurped these keys and you were stuck in the console session until you stopped the program.

Thanks to **Zieg Nielsen** for the info.
